Twenty-one members of the Laurasian ,group of Therevinae (Diptera: Therevidae) are compared using 65 adult morphological characters. Cladistic analysis using parsimony on the 17 ingroup and 4 outgroup taxa provides a well-supported hJpothesis of relationships among taxa within the Cyclotelini, tribe nov. The Cyclotelini is a monophyletic assemblage of mostly New World genera, including Atiolitga, gen. nov., Brtoiprrna Irwin, Coltiana, gen. nov., Crebraxta, gen. nov., Cyclotelus M'alker, .&Jonana, gen.nov., and Oeodireronlyia Bigot. In addition, three Old World genera, dtnniotherem Lyneborg, Bugulaverpa, gen. nov., and Aocyrlotelus Nagatomi & Lyneborg, are included in the tribe. These ten genera are divided into two monophyletic genus-groups, the Breoipenia-group and the Qclotelus-group. Keys are provided for the genera of Cyclotelini. The tribe, the two informal genus-groups, and all genera are diagnosed; five new genera and six new species are proposed. The biogeographical histories of the genera are discussed in terms of their cladistic relationships using methods of cladistic biogeography. Two major vicariant events account for the current distribution of the tribe. The first relates to the Beringian land bridge connecting western North America and eastern Asia. Second, New World cyclotelines were profoundly affected by the Early Eocene breakup of the archipelagic bridge between North and South America, and the distributions support the hypotheses favouring the continental origin of the Greater Antilles.

Macquart and Agapophytus GuCrin-Menkville; Cyclotelini lack, or have a small, inner gonocoxal process); male distiphallus often curved, extending posteroventrally beyond gonocoxites (widespread in Therevidae). Lyneborg (1984) suggested that attention be paid to the possible relationship of

Ammothereva Lyneborg to Ozodiceromyia, due to many species sharing a combination Downloaded from https://academic.oup.com/zoolinnean/article-abstract/129/2/129/2682484 by guest on 24 June 2020 of male genitalic characteristics, e.g. aedeagus attached to subepandrial plate; aedeagus not attached to gonocoxal apodeme or ventral section of gonocoxite; gonocoxite without a free distal inner gonocoxal process; and ventral lobe strongly sclerotized and in an upright position, forming a guide for the distiphallus (an aedeagal guide, in this case). Although his assessment of the relationships of Ammothereva is consistent with the current analysis, in effect placing the genus within the Cyclotelini, most of the characters he used are not synapomorphic for the inclusive group, except for the lack of a free, distal inner gonocoxal process. In the description of Procyclotelus elegans Nagatomi & Lyneborg (1 987), the new genus ProgJclotelus Nagatomi & Lyneborg was suggested to be most closely related to Cyclotelus, a member of the New World group of genera including Cyclotelus, Ozodiceromyia, and Breviperna Irwin. They supported this inclusion based on the following features which they said characterize the group: male genitalia telescopically concealed within the abdomen, and the epandrium consequently shortened and with sharply projecting posterolateral corners; gonocoxites broadly fused ventrally; and midcoxa without pile on posterior surface. Of these characters, the fusion of the gonocoxites and the lack of pile on the posterior surface of the midcoxa proved to be synapomorphic for the Cyclotelini in the current analysis. An epandrium with sharply projecting posterolateral corners is rare in Ozodiceromyia, and is not characteristic of Cyclotelini. Nagatomi & Lyneborg (1989) later state that Procyclotelus has gonocoxites that are divided into two pieces by a median broad ventral ditch and the hypandrium is present, while in Breviperna, Cyclotelus, and Ozodiceromyia the gonocoxites are fused ventrally at least over the anterior third and the hypandrium is absent or is part of the ‘ventral synsclerite’. Our examination of three males of Procyclotelus elegans suggests that the gonocoxites are truly fused and are not divided into two pieces. The degree of gonocoxal fusion within Cyclotelus and Ozodiceromyia is highly variable among species, and there are many species of both genera that match the degree of fusion found in Procyclotelus elegans. In addition, cyclotelines rarely have the hypandrium so fully fused with the gonocoxites as to be visibly absent, and the level of hypandrial fusion with the gonocoxites found in Proyclotelus elegans is similar to that found in all other members. Lyneborg (1989) also suggested that the genus Iberotelus Lyneborg from Spain may be closely related to Cyclotelus and Ozodiceromyia. However, he acknowledged that the characteristic used in implying this relationship, the presence of a sclerotized ‘parameral-aedeagal bridge,’ is likely a part of the groundplan for the family. He noted that Iberotelus is the only therevine genus possessing this characteristic in the Palearctic, Afrotropical, and Oriental Regions. It should also be noted that not all members of Cyclotelus or Ozodiceromyia (or the other cycloteline genera) possess this plesiomorphic condition, and, in fact, Lyneborg (1984) considers the lack of this bridge a synapomorphy that aligns Ammothereva with Ozodiceromyia. Superficial resemblances among different therevid groups seem somewhat com- mon, despite very distant relationships. For example, three genera of Phycinae, Phycus, Pherocera Cole, and Salentia A. Costa, superficially resemble more apomorphic members of the Cyclotelini. In fact, the genus Ozodiceromyia was considered by Becker PHYLOGENY AND BIOGEOGRAPHY OF CYCLOTELINE THEREVINAE 133 (19 12) as a junior synonym of Phycus. Members of other genera of Therevinae can also be easily misplaced into the Cyclotelini due to superficial similarity. For example, species of Euptycus can be confused with members of Orodiceromyia, and one species, Orodiceromyia mexicana Bigot, was also described as Euphycus setosus Krober (19 12g).

Species of Psilocephala such as Psilocephala munda Loew, species of Nebiitus Coquillett Downloaded from https://academic.oup.com/zoolinnean/article-abstract/129/2/129/2682484 by guest on 24 June 2020 such as Nebritus pellucidus Coquillett, and most species of the predominantly African genus Schoutedenomyia Krober, externally appear closely related to Orodiceromyia, with the most obvious similarities being the shiny black frons and abdominal tergites of the females in these genera. In all of these cases, examination of internal male and female genitalia and of informative external characters provides strong evidence that they are not closely related. Lyneborg (1976) noted the superficial similarity between Schoutedenomyia and Furcijira ( = Cyclotelus), pointing to various characteristics held in common, including body shape, antennal shape and vestiture, similar placement and appearance of the antennal style, lack of dorsocentral setae, wings without structural differences, and reddish-brown male terminalia telescoped into the abdomen. However, he also noted numerous fundamental differences, especially in the male genitalia. He noted this as an excellent example of parallelism, with the genera occupying the same ecological niches in tropical and subtropical environments of the Old and New World, respectively. It also seems likely that many of these genera are mimics of sphecoid wasps, further explaining the observed parallelism.

METHODS

Specimens were examined using a Wild/Leica MZ8 binocular dissecting micro- scope with a range of mapification between 6.3 and 50 x . A minimum of two male specimens and two female specimens was examined for each species, except for the single pair (male and female) of Bugulaverpa rebeccae, sp. nov., the single males of Crebraseta crassicornis (Bellardi) and Coleiana nigricopis, sp. nov., and the single specimen (male) of Iberotelus cinereus Lyneborg. Additional specimens were studied for several taxa to clarify states of certain characters. For each species, at least one male abdomen and one female abdomen were macerated in 20% KOH at room temperature for 8 hours. After the initial three hours, most of the pleural membrane of one side of each abdomen was teased apart to allow internal tissues direct contact with KOH. After maceration, the specimens were soaked in distilled water for 10 minutes and placed into 75% ethanol. Male terminalia were placed into glycerin for dissection of genitalia and microscopic examination. Female abdomens were carefully opened laterally by teasing apart all remaining pleural membrane, including that of segment 8. Several drops of a 40% solution of chlorazol black (chlorazol black powder dissolved in 75% ethanol) were introduced into the opened abdomen using the tips of a fine forceps. The abdomens were then rinsed with 75% ethanol and checked to determine if spermathecal ducts and sacs were dyed blue. If not, the specimen was remacerated for several hours or the tissues were teased apart to expose the ducts and sacs, after which another several drops of chlorazol black were placed in the apical part of the abdomen. When the ducts were sufficiently stained, the specimen was rinsed in 75% ethanol and placed into glycerin for microscopic examination. Further dissection of these fragde structures consisted only of teasing tissues with minuten probes and fine Downloaded from https://academic.oup.com/zoolinnean/article-abstract/129/2/129/2682484 by guest on 24 June 2020 Downloaded from https://academic.oup.com/zoolinnean/article-abstract/129/2/129/2682484 by guest on 24 June 2020 I36 S.

CHARACTER DESCRIPTIONS

In this section, we describe the morphology and taxon distribution of states for the 65 characters used in this analysis. Of these, 15 are in the head, 18 are in the thorax, 26 are in the male terminalia, and 6 are in the female terminalia. Most are binary, with few showing three states: 11, 15, 48, 51, 52, and 60, and four states: 8 and 9. Character distributions are discussed relative to the presented cladogram (Fig. 1).

Head

1. Antennal length 0 shorter than or subequal to head length 1 longer than head Antennal length was measured from dorsal view, and the length of the head was measured from lateral view. Plesiomorphically, the antenna is the same length or shorter than the head (e.g. Fig. 33), as is the case for all outgroup taxa and most Therevidae. A specimen with antennae >20% longer than the head (e.g. Fig. 27) was scored as having the apomorphic state. This character and the following two supported no clades in the current analysis. However, the three characters may be useful when considering species level relationships. For example, several species with elongate antennae within Ozodiceromyia are closely related to Ozodiceromyia argenttjra (Gaimari & Irwin, 2000) (e.g. Figs 26 and 27). The same holds true for several species within Qrlotelus being related to Cyclotelus beckeri (e.g. Figs 36 and 37). The apomorphically elongate antenna was only found in these two terminal ingroup taxa, but has arisen independently in many genera of Therevidae.

2. Antennal scape width 0 same thickness or thinner than first flagellomere 1 distinctly thicker than first flagellomere The scape and first flagellomere are measured through their broadest widths in dorsal or lateral view. In the plesiomorphic state, as represented by 3 of 4 outgroup taxa and most other Therevidae, the scape is the same thickness as (e.g. Fig. 29) or thinner than (e.g. Fig. 13) the first flagellomere. To be scored as possessing the apomorphic state, the scape is >20% wider than the first flagellomere (Fig. 23), which is autapomorphic for Crebraseta.

Plesiomorphically, the upper frons of the female has scattered setae, at most with a bare area along the midline (e.g. Figs 8 and 15), as is the case for all outgroup taxa and the Breviperna-group. As a synapomorphy for the Cyclotelus-group, setae are absent or are in defined patches or patterns, usually in one or more vertical lines

(e.g. Fig. 23) or in a small cluster medial to the eye margin (e.g. Fig. 27). Downloaded from https://academic.oup.com/zoolinnean/article-abstract/129/2/129/2682484 by guest on 24 June 2020

11. Setae of 0 lower3ons 0 . scattered 1 in defined patches or patterns 2 absent Usually, the lower frons bulges forward beyond the upper frons in lateral view; otherwise, the lower frons is delimited above by a change in direction of the inner eye margin. This character is scored on the basis of presence of setae just above the antennal base margin. As in character 10, the lower frons of the female has scattered setae (e.g. Figs 15 and 23) plesiomorphically, as is the case for 3 of 4 outgroup taxa. Apomorphically, there are setae in defined patches or patterns (state l), usually a small cluster dorsolateral of the antennal base margin (e.g. Fig. 27), as is synapomorphic for the Ozodicemmyia-subgroup. The lack of setae or pile above the antennal base margin (state 2) (e.g. Figs 8, 19, and 33) is widespread within the Cyclotelini, in both the Breviperna-group and the Cyclotelus-subgroup, and likely arose at the base of the tribe. Brevipenza placida and Crebraseta crassicornis each display scattered setae.

12. Maxillary pa& colour 0 dark brown or black 1 orange Plesiomorphically, the maxillary palp is dark, as is the case for all outgroup taxa and for the Cyclotelus-group. The palp is apomorphically orange, as is synapomorphic for the Breviperna-group. Members of the Cyclotelus-group rarely have an orange palp, including few species of Ozodiceromyia not included in these analyses.

13. Gena 0 not protruding 1 protruding anteriorly beyond edge of eye Plesiomorphically, the gena is not visible from lateral view, as is the case for all outgroup taxa. This character was scored as protruding if the gena was visible below the eye margin from the lateral view as a raised convexity, ranging from small (e.g. Fig. 10) as in Ammothereva to large (e.g. Fig. 23) as in the Ozodiceromyia-group. The protruding gena is synapomorphic for the Cyclotelini, with a subsequent reduction in Coleiana (e.g. Figs 32 and 33).

14. lip ofgena 0 same texture and colour as remainder of gena, postgena, occiput, and parafacial 1 different texture or colour than remainder of gena, postgena, occiput, or parafacial As is the case for all outgroup taxa and most Therevidae, the genal apex is PHYLOGENY AND BIOGEOGRAPHY OF CYCLOTELINE THEREVINAE 141

plesiomorphically of the same texture and colour as the remainder of the gena, postgena, occiput and/or parafacial (e.g. Figs 14 and 15). In the apomorphic state, a patch of different texture or colour (e.g. Fig. 35) is present, usually as distinctly darker pruinescence, but occasionally consisting of velutinous pruinescence. This is

synapomorphic for the Cyclotelus-group, with a subsequent change to state 0 in Downloaded from https://academic.oup.com/zoolinnean/article-abstract/129/2/129/2682484 by guest on 24 June 2020 Coleiana.

15. Pile Ofgenal apex 0 not different from pile of postgena or lower occiput 1 forming distinctive patch of shortened pile 2 absent As is the case for 3 of 4 outgroup taxa, the genal apex plesiomorphically has setae or pile that is similar to that of the postgena or lower occiput. A dense patch of short, darkened setae on the genal apex (state 1) (e.g. Figs 20 and 23) is synapomorphic for the Ozodicmmyia-subgroup and autapomorphic for Anolinga me- lanothrix, while having the apex without pile (state 2) (e.g. Fig. 8) is otherwise synapomorphic for the Cyclotelini.

Thorax

16. Clej ofthe prosternum 0 pilose 1 lacking pile Pile on the cleft of the prosternum has been used as a key character for sorting genera of therevids (Irwin & Lyneborg, 1981a,b). Plesiomorphically, as is the case for 3 of 4 outgroup taxa, the Ozodicmmyia-subgroup, and most of the Brevipaa- group, prosternal pile is present in the cleft. Apomorphically, the prosternum lacks pile in the cleft, as in the Cyclotelus-subgroup, the Ammothreua gussakovs,$+group, and Anolinga psi10jbn.s.

17. Proepimmn 0 pilose 1 lackingpile The upper half of the proepimeron is pilose plesiomorphically, as in 2 of 4 outgroup taxa and many other therevid genera. The lack of pile on the proepimeron (e.g. Figs 40 and 41) occurs throughout the Cyclotelini, except Brevipema, and is herein considered apomorphic.

18. Katepisternum 0 pilose 1 lacking pile As in 3 of 4 outgroup taxa, the katepisternum is pilose plesiomorphically. Apomorphically, this pleurite lacks pile (e.g. Fig. 40), as. is the case for the Cyclotelini, with subsequent changes to state 0 in Brevipaa, part of Anolinga, and the Ozodiceromyia- subgroup. In the Ozodiceromyia-subgroup, this pile is located along the median vertical convex crest of the pleurite (e.g. Fig. 41).

D. GAIMARI AND M. E. IRWIN pale macrosetae is synapomorphic for Ammothereva, although a few species within the genus, such as Ammothereva mongolica (Zaitsev) and Ammothereva splendida (Krober), have darker, nearly black macrosetae. In addition, a few species of Ozodiceromyia that were not included in the analyses also have pale macrosetae, as do other unrelated

genera, such as Arenigena Irwin & Lyneborg and Ammonaios Irwin & Lyneborg. This Downloaded from https://academic.oup.com/zoolinnean/article-abstract/129/2/129/2682484 by guest on 24 June 2020 state is quite uncommon among therevids, and is certainly apomorphic within specific groups.

28. .Notal texture 0 fully pruinose 1 with reduced pruinescence As is found in all outgroup taxa and the Breviperna-group, the notum is plesio- morphically fully pruinose, with no areas that are reduced to the point of exposing ground colour. Apomorphically, a reduction of pruinescence on the notum exposes some ground colour. Most often, the lateral notum or the postpronotal lobe displays this reduced pruinescence, although the reduction can be much more extensive. This is a synapomorphy for the Cvclotelus-group.

29. Patches of matte pruinescence on notum 0 absent 1 present As is found in all outgroup taxa and most Therevidae, the notum plesiomorphically lacks patches of matte pruinescence. There are patches of matte pruinescence on the notum as a synapomorphy for Coleiana+ Cyclotelus. These patches are dull black or brown in Cyclotelus and dark brown in Coleiana, and are usually located on the mesonotum between the midline and lateral edge.

30. Scutellar setae 0 2 pairs 1 0-1 pair As in all outgroup taxa and most Cyclotelini, two pairs of scutellar setae are present plesiomorphically. Apomophically, 0-1 (usually 1) pair of scutellar setae are present, as is autapomorphic for Bugulaverpa. In addition, the South American clade of Cyclotelus beckeri+ Cyclotelus kroeberi is supported by the apomorphic condition, and this may be an important state in the generic revision of Cyclotelus underway.

31. Supra-alar setae 0 2 pairs 1 1 pair As is found in all outgroup taxa and most Cyclotelini, two pairs of supra-alar setae are present. Apomorphically, one pair of supra-alar setae is present, as is autapomorphic for Bugulaverpa. In addition, the South American clade of Cvclotelus beckeri+ Cyclotelus kroeberi is supported by the apomorphic condition, and this may be an important state in the generic revision of Cyclotelus underway.

32. Ventral surface of basal lobe ofcosta 0 with pile over entire ventral surface 1 bare, or with short pile only basally PHIZOGENY AND BIOGEOGRAPHY OF CYCLOTELINE THEREVINAE 145

As is the case for all examined outgroup taxa, the entire ventral surface of the basal lobe of the costa is densely covered with black or white pile (e.g. Fig. 48). Apomorphically, pile is absent or short pile is sparsely distributed only at the base of this lobe (e.g. Fig. 49). All Cyclotelini except Breviperna display this apomorphic

condition, and it is considered a synapomorphy of the tribe. Downloaded from https://academic.oup.com/zoolinnean/article-abstract/129/2/129/2682484 by guest on 24 June 2020

33. Basal lobe of the costa with dorsal setae 0 scattered over entire surface 1 in two distinct rows The dorsal surface of the basal lobe of the costa has short, black setae that extend into the inner and outer rows of costal setae. In the plesiomorphic condition, as is the case for 3 of 4 outgroup taxa and the Breviperna-group, these setae are scattered over the entire dorsal surface (e.g. Fig. 50) and do not form distinct lines leading into the inner and outer setal rows of the costa. In the apomorphic condition, as found in most members of the Cyclotelus-group (except Procyclotelus and Crebraseta), there is an upper row along the outer edge of the lobe that leads to the anterior row of costal setae, and a lower row along the base of the lobe that leads to the posterior row of costal setae (e.g. Fig. 51). A distinct linear bare area exists between these upper and lower rows.

Male teminalia

34. Lateral ejaculatory process 0 incomplete dorsally 1 notched or complete dorsally Plesiomorphically, the lateral ejaculatory process is incomplete dorsally and is composed of two distinct sclerites, as is found in all outgroup taxa. Apomorphically, the process is complete dorsally (e.g. Fig. 135) or is at most notched along the anterior edge (e.g. Fig. 133). This notch can be deep, but the lateral ejaculatory process is distinctly a single structure. This is a synapomorphy for the Cyclotelini, but some members of the Ammothereva poecilopa-group display state 0.

35. Lateral ejaculatory process 0 set into aedeagus 1 separated and external Plesiomorphically, the lateral ejaculatory process is sunken into the aedeagus (e.g. Fig. 132), as in all outgroup taxa. Apomorphically, the lateral ejaculatory process is large and appears completely separated from the aedeagus anteriorly, as in Breviperna (Figs 118 and 1 19), Procyclotelus (Figs 136 and 137), and some Ammothereva such as Ammothereva nigrofmorata (Krober), although it is held in place with muscle and membrane.

36. Relative orientation of lateral margins of dorsal apodme 0 parallel, or slightly convergent anteriorly 1 divergent anteriorly All outgroup taxa display the plesiomorphic condition of having parallel (e.g. Fig. 133) or slightly converging (e.g. Figs 11 1 and 113) lateral margins of the dorsal Downloaded from https://academic.oup.com/zoolinnean/article-abstract/129/2/129/2682484 by guest on 24 June 2020 Downloaded from https://academic.oup.com/zoolinnean/article-abstract/129/2/129/2682484 by guest on 24 June 2020 148 S. D. GAIMARI AND M. E. IRWIN 45. Postemlateral comers of epandrium 0 flange-like and without setae, at least distally 1 flange absent, setose over posterolateral corners As in all outgroup taxa and most genera of Cyclotelini, the epandrium is

plesiomorphically dorsoventrally flattened and flange-like at the posterolateral cor- Downloaded from https://academic.oup.com/zoolinnean/article-abstract/129/2/129/2682484 by guest on 24 June 2020 ners, which lack setae (e.g. Fig. 69). Apomorphically, the posterolateral corners are not flattened flanges, and setae are present over the entire posterior epandrium, including the posterolateral corners (e.g. Fig. 65); this is synapomorphic for the Ozodiceromyia-subgroup. Even when the flange is absent, the posterolateral corners of the epandrium can be pointed (e.g. Fig. 65).

46. Anterior e&e of epandrium 0 emarginate 1 not emarginate According to 3 of 4 outgroup taxa, the plesiomorphic condition is to have an epandrium with an emarginate anterior edge in dorsal view (e.g. Fig. 62). Apomorphically, this anterior edge is not emarginate in dorsal view (e.g. Figs 63 and 68), as is the case for much of the Cyclobhs-group, but notably not for the Old World members.

47. Epandrial setae 0 covering more than two-thirds of epandrium 1 covering only posterior half of epandrium As in all outgroup taxa and most therevids, setae covering more than two-thirds of the epandrium (e.g. Fig. 68) is plesiomorphic. The condition of having setae covering at most the posterior half of the epandrium (e.g. Fig. 64) is a synapomorphy for Ozodicemmyiu.

48. Fusion ofgonocoxites 0 completely free 1 fused by sclerotized membrane between discernible gonocoxites 2 strongly fused Plesiomorphically, the gonocoxites are free in Therevidae, including all outgroup taxa. Although gonocoxal fusion occurs in other groups of Therevidae, this condition is synapomorphic for the Cyclotelini. Most commonly, the gonocoxites are completely fused (state 2) (e.g. Fig. 93). The length of the area of fusion between the two halves ranges from long, as in Coleiana (Fig. 99), to short, as in Aocyclotelus (Fig. 97). The gonocoxites can also be seen as distinct, but with a sclerotized sheet between (state 1) (e.g. Figs 72, 73, and 75), as in Ammotheva.

49. Hypandrium 0 free or absent 1 fused to gonocoxites The plesiomorphic condition, as is found in all outgroup taxa, is for the hypandrium to be free and separate from the gonocoxites or absent. The condition of having the hypandrium fdly fused to the gonocoxites (e.g. Figs 93 and 103)is a synapomorphy for the Cyclotelini. Although the hypandrium is fused to the gonocoxites, it is rarely PHYLOGENY AND BIOGEOGRAPHY OF CYCLOTELINE THEREVINAE 149 indistinguishable. In addition, examination of male genitalic musculature (following terminology of Ovtshinnikova, 1989), and (Ovtshinnikova & Yeates, 1998) of Ozodiceromyia nanella verified that the hypandrial muscle M 18, (and therefore the hypandrium itself) is present despite full fusion with the gonocoxites. In some

Outer gonocoxal process 0 strongly everted 1 small fold, flattened flange, or absent The outer gonocoxal process is considered large and everted if it projects posteriorly by at least half the length of the gonocoxite itself (e.g. Figs 77, 78, 103, and 104). The plesiomorphic condition of having this strongly everted outer gonocoxal process is present in 2 of 4 outgroup taxa and nearly all genera of cyclotelines. The apomorphic state of lacking an outer gonocoxal process or having a small fold or flattened flange (e.g. Figs 91 and 92) is characterized by a more delicate appearance (if present) and a length shorter than half that of the gonocoxite (e.g. Fig. 94). The reduced outer gonocoxal process is synapomorphic for Ozodiceromyia.

51. Set& of the outer gonocoxal process 0 similar to that of gonocoxites 1 reduced density and size, or absent 2 dense and fine The outer gonocoxal process (or the corresponding edge of the gonocoxite in those lacking the process) having setae similar to those of the gonocoxites (e.g. Figs 76, 82, and 104) represents the plesiomorphic condition, which is found in 2 of 4 outgroup taxa and most cycloteline genera. As a synapomorphy for the Ozodiceromyia- subgroup, the process or edge has, at most, only a few short setae that are smaller and finer than other setae of the gonocoxites (state 1) (e.g. Fig. 94). As a synapomorphy for Anolinga, the gonocoxal process is densely covered with fine setae, which are finer and more densely distributed than other gonocoxal setae (state 2) (e.g. Fig. 85).

52. Inner gonocoxal process 0 strongly projecting and articulated 1 strongly projecting and not articulated 2 neither strongly projecting nor articulated The inner gonocoxal process (see Ovtshinnikova & Yeates, 1998) is strongly projecting and articulated in 1 of 4 outgroup taxa and in the Gondwanan Therevinae not included in this analysis (Anabarhyuhus-group and Agapophytus-group). The ar- ticulation is apomorphically lost, but the process is still strongly projecting in 2 other members of the outgroup. The inner gonocoxal process is reduced to a knob (e.g. Fig. 96) or is absent (e.g. Fig. 74) as is the case for the Cyclotelini and for the nearest outgroup taxon, Brachylinga cinerea.

Having the origin of these ducts at the base of the central sac (e.g. Fig. 148) is synapomorphic for Nesonana +Anolinga + Breviperna, and is present within Ozodiceromyia (e.g. Fig. 153).

Basal portion of individual spemnathecal ducts 0 same width as, or narrower than, common spermathecal duct 1 wider than common spermathecal duct As in 3 of 4 outgroup taxa and most Cyclotelini, the basal portion of the spermathecal duct is plesiomorphically the same width or narrower than the common spermathecal duct (e.g. Fig. 153). Apomorphically, the basal portion of the spermathecal duct is wider that the common spermathecal duct (e.g. Fig. 156). This widened spermathecal duct is a synapomorphy for Cyclotelus.

64. Anterior furcal membrane 0 lacking a furcal bulla 1 with a furcal bulla Nearly all Therevidae considered except Cyclotelini plesiomorphically lack a furcal bulla on the anterior part of the furcal membrane, which is instead flattened. The two exceptions (Lysilinga aurantiuca (Coquillett) and an undescribed genus from Mexico) have a dorsal extension of the furca that appears directly associated with a dorsal lobe on the 8 distiphallus. The presence of a furcal bulla is synapomorphic for the Cyclotelini, with a subsequent change to state 0 in Bugulaverpa (Fig. 150). This structure, which can be lightly to heavily sclerotized, ranges in size from large and distinct (e.g. Fig. 148) to a small convexity along the anterior furcal edge (e.g. Fig. 147).

65. Dorsocentral connection oftergite 8 with tergite 9 0 setose 1 lacking setae Among Laurasian Therevinae, the ribbon-like dorsocentral connection between tergites 8 and 9 is plesiomorphically setose, as in 3 of 4 outgroup taxa. These setae are absent, leaving the structure bare, as a synapomorphy for the Cyclotelini. This apomorphy is very consistent within the Cyclotelini, but is widespread in more distantly related therevids, indicating a possible reversed polarity when considering higher level phylogenetic relationships.

CLADISTIC ANALYSIS AND RESULTS

Phylogenetic analyses follow the cladistic philosophy of parsimony promoted by Hennig (1966) and other workers (e.g. Wiley, 198 1; Farris, 1983). Following Kluge (1989), the relative informativeness of characters is not prejudged by excluding characters that seem to be in opposition, and so all evidence available to us was analysed. In addition, following Yeates & Irwin (1996), characters were not excluded due to their perceived level of homoplasy, agreeing that this would amount to an a priori exclusion of evidence for some possible hypotheses of relationship as a method PHYLOGENY AND BIOGEOGRAPHY OF CYCLOTELINE THEREVINAE I53 for protecting a preconceived hypothesis prior to parsimony analysis. Following Yeates (1992), autapomorphies were left in for analyses, as these character states may be found to be more widespread and may support clades in undiscovered or not included relatives of the terminal taxa.

Outgroups were used to determine character polarities (Watrous & Wheeler, Downloaded from https://academic.oup.com/zoolinnean/article-abstract/129/2/129/2682484 by guest on 24 June 2020 1981; Farris, 1982; Maddison, Donoghue & Maddison, 1984; Nixon & Carpenter, 1993). Cladistic analyses were performed using PAUP version 3.1.1 (Swofford, 1993) and HENNIG86 version 1.5 (Farris, 1988) using the data matrix presented in Appendix 2. All characters were treated as non-additive, agreeing with Hauser & Presch (1991) and Hauser (1992) that congruent characters in a matrix are the evidence for the order of transformation series for multistate characters. A priori rejection or down-weighting of other possible transformation series can be used as an ad hoc assumption to protect a preconceived hypothesis, instead of using congruence with other characters to test ordering hypotheses with all possibilities equally available. PAUP analysis followed a random addition sequence order of 100 iterations, utilizing the non-exhaustive (heuristic) tree bisection-reconnection (TBR) branch swapping algorithm. HENNIG86 analysis was performed using the ‘m*; bb*’; commands (i.e. branch breaking algorithm). Cladogram figures displaying character state changes were prepared using CLADOS version 1.6.1 (Nixon, 1998) under ACCTRAN character optimization (Swofford & Maddison, 1987). Although Yeates & Irwin (1 996) considered DELTRAN optimization to be more conservative due to its biases against single origins of characters (Wheeler, Cartwright & Hayashi, 1993), we consider ACCTRAN to be more conservative, based, in part, on the arguments of Pinna (199 1) that primary homologies should be considered valid until parsimony positively falsifies them. Both analyses produced one most parsimonious tree (Figs 1 and 2) of length 166, Consistency Index (Kluge & Farris, 1969) of 0.45 (0.44, excluding autapomorphies), Retention Index (Farris, 1989) of 0.69, and Rescaled CQnsistency Index (Farris, 1989) of 0.3 1. The topology remained stable through succkive weighting (Farris, 1969; Carpenter, 1988) as implemented by HENNIG86 (i.e. m*; bb*; xs w; cc;) and PAUP (by the maximum value of the Rescaled Consistency Index, with a base weight of 1000), levelling out at a single iteration. Because the expected amount of homoplasy increases with the number of taxa in a parsimony analysis, the regression equation of Sanderson & Donoghue (1989: 1785) was used to calculate an expected value for the Consistency Index. The calculated value of 0.53 for 21 taxa is greater than the value indicated in the current analysis (0.45), so there is more homoplasy than expected for an analysis with this number of taxa under the 1989 model. The relatively high Retention Index indicates that a high proportion of the potential synapomorphies in the data matrix are present as homologies on the cladogram.

Xode support

Assessing cladogram or node support is a difficult endeavour, especially with the variety of available, standard methods which do not necessarily reflect cladogram or node support. Of the methods discussed below, only Bremer support (Bremer, 1988, 1994; Donoghue et al., 1992; Kallersjo et al., 1992) (decay index, branch support) is founded upon utilizing the entire original data set throughout, rather Downloaded from https://academic.oup.com/zoolinnean/article-abstract/129/2/129/2682484 by guest on 24 June 2020 Downloaded from https://academic.oup.com/zoolinnean/article-abstract/129/2/129/2682484 by guest on 24 June 2020 156 S. D. GAIMARI AND M. E. IRWIN should provide a better estimate for the amount of additional realistic character data that would be necessary to refute a node on the cladogram.

CLASSIFICATION

The structuring of the internal classification of the Therevidae is in its infancy. Not until recently (Irwin & Lyneborg, 198 1a) was the family even divided into two subfamilies, Therevinae and Phycinae. Irwin & Lyneborg (198 la) also provided the first classification of known Nearctic species, delimiting genera and changing the combinations of species based on putative synapomorphies, but gave no insight into the suprageneric groupings below subfamily. As presented in the historical perspective, other workers have published opinions on relationships of various genera to Ozodicmmyia and Cyclotelus, but have not attempted to reflect these opinions through formal classification. For example, Cole (1923) stated that the genera Furcijira and Epomyia (both currently junior synonyms of Cyclotelus) are very near to Psilocephala. The genus Psilocephala was broadly defined, and prior to Irwin & Lyneborg (1981a), was a polyphyletic assemblage of groups lacking pile on the parafacial. However, the most speciose and abundant group within Psilocephala was Cole’s ‘haemorrhoidalis-group’, all species of which are now members of Orodiceromyia. The fact that Cole formally described this species-group in his treatment of Psilocephala, and included it in his keys, indicated that Cole considered this a monophyletic taxon. However, he had not associated the group with the monotypic Ozodiceromyia and he did not officially separate it from Psilocephala. In addition, Cole (1923) recognized several species of lhereva to appear closer to Psilocephala, but again, did not change their generic status nor recognize the association with Ozodiceromyia, where they are currently placed. Malloch (1932) also had notions of the relationship of “the generally accepted forms of Psilocephala” ( = Ozodiceromyia) with Furcijira ( = Cyclotelus). Cole (1960b) agreed with this assessment and pointed to the possible relationship of Furcfia to Ozodiceromyia in the strict sense. A few recent workers have recognized this group as a distinct entity. Ozodiceromyia, Cyclotelus, and Breviperna were cited as forming a distinct New World group (Nagatomi & Lyneborg, 1987, 1989), with the addition of Procyclotelus from the Far East as a close relative of Cyclotelus itself. Irwin & Lyneborg (1981b) also mentioned the ‘Cyclotelus-group’ as containing Cyclotelus and Ozodiceromyia, but also included Chro- molepida, which the current analysis rejects. They noted that the genera aligned with Cyclotelus have a strong Central American base, with strong ties to genera in North and South America. The hypotheses being formulated in this study are among the first to be rigorously tested in an attempt to reflect the phylogeny of groups within the Therevidae below the subfamilial level, so it is important to erect a phylogenetically-based classification which is more biologically informative than other currently construed classification schemes (Hennig, 1966; Farris, 1979; Wiley, 1980). The classification presented in Appendix 3 follows phyletic sequencing of taxa (Nelson, 1969, 1972, 1973), rather than employing the system of strictly giving sister-groups equivalent ranks. This PHYLOGENY AND BIOGEOGRAPHY OF CYCLOTELINE THEREVINAE 157 study is an attempt to establish a firm foundation for organizing higher-level groupings of Laurasian Therevinae, and to aid further study of genera within the C yclotelini. Downloaded from https://academic.oup.com/zoolinnean/article-abstract/129/2/129/2682484 by guest on 24 June 2020 Cyclotelini, tribe nov.

The resulting cladogram (Figs 1 and 2), the unweighted Bremer support index of 8 additional steps, and the rescaled Bremer support index of 20.3 steps, demonstrate that the Cyclotelini is a monophyletic group supported by synapomorphies. The hypothesized Late Cretaceous origin for this group, as discussed in the bio- geographical section of the current study, justifies the assignment of tribal rank. The two major monophyletic groups within the Cyclotelini are placed into informal genus-groups. These genus-groups are: the Brevipema-group, including Ammothereva, Anolinga, Brevipema, and Nesonana; and the Cyclotelus-group, which is divided into two monophyletic clades, or subgroups, the Cyclotelus-subgroup (Culeiana, Cyclotelus, and Procyclotelus), and the Ozodiceromyia-subgroup (Bugulaverpa, Crebraseta, and Ozodiceromyia). The genus-groups are diagnosed along with the included genera. The formal classification of the Cyclotelini, with the informal groupings included, is presented in Appendix 3. Diagnosis. The Cyclotelini can be recognized using a suite of external and internal characters. Externally the Cyclotelini lack pile on the posterior surface of the midcoxa, although it is present in the poecilupa-group of Ammuthereva, and is sparsely present in some specimens of Breznperna. The gena usually protrudes beyond the edge of the eye, at least slightly, and the gena often has a distinctive patch that differs in texture, colour, or pile from the rest of the lower occiput. Usually, the male ommatidia are larger on the dorsal than the ventral halves of the compound eye. The ventral surface of the basal lobe of the costa usually lacks pile, or has sparse short pile basally. Internally, males of all Cyclotelini have fused gonocoxites, including a fused hypandrium. The gonostylus is hinged on a gonostylar condyle rather than being hinged on the inner edge of the gonocoxite as in other therevids. The inner gonocoxal process is small and nonarticulated. In the female, the anterior portion of the furca is characterized by the presence of a furcal bulla, and the ribbon-like dorsocentral connection between tergites 8 and 9 lacks setae or pile. As in all Therevidae, spermathecae are not sclerotized. Cyclotelines have 2 spermathecae and a central sac. Synapomorphies. 9 lower frons lacking setae (character 11, state 2) (setae present within the Ozodiceromyia-subgroup, and in Brevipema); gena protruding forward beyond lower edge of eye (character 13) (gena not protruding in Coleiana); genal apex bare of setae (character 15, state 2) batch of distinctive setae (state 1) present in Ozodicmmyia-subgroup and in part of Anolinga); posterior surface of midcoxa lacking pile (character 20); ventral surface of basal costal lobe lacking pile, or with sparse short pile basally (character 32) (fully pilose in Brevzpema); lateral ejaculatory process complete or notched dorsally (character 34); ejaculatory apodeme of uniform width in dorsal view (character 40) (expanded anteriorly in part of Ozodicmmyia and in the clade of Coleiuna + Cyclotelus); gonocoxites strongly fused (character 48, state 2) (fused through sclerotized sheet (state 1) in Ammothereva); hypandrium fused to gonocoxites (character 49); gonostylus hinged to gonocoxite on gonostylar condyle (character Downloaded from https://academic.oup.com/zoolinnean/article-abstract/129/2/129/2682484 by guest on 24 June 2020 Downloaded from https://academic.oup.com/zoolinnean/article-abstract/129/2/129/2682484 by guest on 24 June 2020 160 S.

Genus-groups, genera, and specie5

To reflect the two monophyletic clades within the tribe, the genera are divided into two informal genus-groups. Within each genus-group, the genera are presented alphabetically, without regard to subgroup. Species within each genus annotated with ** were used in the phylogenetic analyses of the current study. An exhaustive list of references for each previously described taxon is provided by Gaimari (1998), but only taxonomically relevant references are listed herein. Within species descriptions, values in [ ] represent the values taken from paratypes of the same sex. Abbreviations for repositories follow Arnett, Samuelson & Nishida (1993), and are listed in Appendix 4. This manuscript was prepared and submitted long before the 4th edition of the International Code of Zoological Nomenclature was available (see Art. 86.1). All new nomenclatural acts except the lectotype designations conform to this edition. While each lectotype designation is specific for one nominal taxon, we here state that each and every one of these designations is for the sole purpose of fixing and stabilizing the current concept of the taxon.

Breviperna-group

Diagnosis. Members of this group display full pruinescence on the frons, pleura, and notum, with no areas of shiny black, velutinous, or matte pruinescence. They typically have an antenna1 first flagellomere that is onion-shaped, or bulbous basally, tapering to the tip. In addition, the style is terminal on the first flagellomere. The PHYLOGENY AND BIOGEOGRAPHY OF CYCLOTELINE THEREL’INAE 163 maxillary palps are orange. The 9 upper frons possesses scattered setae, or setae are occasionally in defined patches. The genal apex usually lacks any patch of distinctive colour or texture and usually lacks pile. The foreleg is normal, with no swollen or enlarged parts. On the wings, the setae of the basal lobe of the costa are

scattered over the entire surface, extending into both outer and inner costal rows.

Ammothereva Lyneborg

Ammothereva Lyneborg, 1984: 206 (incl. revision, illust.: numerous, e.g. antennae, heads, 8 genit.). Type species, Psilocephala gussakovskyi Zaitsev, by original designation. Majer, 1997: 522 (key ref., key does not work for Ammothereva), 523 (illust.: 9 head). Diagnosis. The best diagnosis, with the most complete consideration of the species is found in Lyneborg (1984). An attempt to diagnose this genus here, without all of the necessary specimens, would be incomplete, especially when the genus was revised so recently and no new species or combinations have since been recognized. A few comments are in order, however. Within the Cyclotelini, this is the only genus that regularly displays the state of having pale macrosetae of the notum, head, coxae, and legs. Also, the epandrium is consistently longer than wide (e.g. Figs 56 and 57). Interestingly, this genus seems to be variable in certain characters which are not variable in other groups of Cyclotelini. Ammothereva lepida Lyneborg and Ammothereua salentioides Lyneborg have a conical first flagellomere rather than the more typical basally-bulbous first flagellomere. Ammothereva mesasiatica (Zaitsev) and Ammothereva salentioides have males with the eyes separated by a distance greater than the anterior ocellus. Species in the poecilopa-group have a pilose prosternal cleft while others lack pile, and Ammothereva salentioides has pile on the posterior surface of the midcoxa, a state shared by no other member of the tribe except atypical specimens of Breviperna. In the male genitalia, Ammothereva n&gemorata and Ammothereva gussakovskyi have the lateral ejaculatory process enlarged and anteriorly separated from the aedeagus as is found in Breviperna and Procyclotelus. Many of these differences may be attributable 16.1 S. D. GAIMARI AND M. E. IRWIN to the ancient divergence and geographical separation (and therefore open niches available) of this genus from the remainder of the tribe. Synapomorphies. Prosternum lacking pile (character 16) (pile present in poecilopa-group); macrosetae of head, notum, coxae, and/or legs pale (character 27) (dark, or nearly black in few species); epandrium longer than wide (character 44); gonocoxites fused Downloaded from https://academic.oup.com/zoolinnean/article-abstract/129/2/129/2682484 by guest on 24 June 2020 by sclerotized membrane between discernible gonocoxites (character 48, state 1).

This genus was only recently treated by Irwin (1977a) and Irwin & Lyneborg (1981a). Since that time, no new species have become apparent, so we only provide additional morphological and distributional information for the de- scribed species.

PHYLOGENY AND BIOGEOGRAPHY OF CYCLOTELINE THEREVINAE 171 Diagnosis. This large bodied species has an antenna1 scape that tapers distally and is as thick as the first flagellomere. This is one of the few groups known within the Cyclotelini where the male compound eyes are dichoptic, separated by a width greater than the anterior ocellus (Fig. 14) (certain members of Ammothereva also share

this condition). The same is true for the condition of having scattered setae on the Downloaded from https://academic.oup.com/zoolinnean/article-abstract/129/2/129/2682484 by guest on 24 June 2020 female lower frons, which bulges in Brevz$erna placida (Fig. 15). There is one pair of dorsocentral setae. The prosternum has white pile. The proepimeron is pilose on the upper half. The katepisternum is also pilose, as is the case for part of the related genus Anolinga. The posterior surface of the midcoxa occasionally has sparse pile, but this is thought to be an aberration and not a characteristic for the species. On the wing, cell m3 is open, or occasionally closed at the edge of the wing. Of the Cyclotelini, this is the only member with pile covering the ventral surface of the basal lobe of the costa (Fig. 48). The gonostylus lacks a subapical, lateral spur. The aedeagus (Figs 118 and 119) is characterized by having a short dorsal apodeme with a slightly longer ventral apodeme, and an ejaculatory apodeme with a large posterior tip. The lateral ejaculatory process is greatly enlarged and appears separated anteriorly from the remainder of the aedeagus. The furcal bulla in this species is quite large and distinct (Fig. 148), with the long common spermathecal duct originating on the furca basal to the furcal bulla. The spermathecal ducts originate from the base of the large, round, central sac.

Common spermathecal duct 6.60 mm long; wider than spermathecal ducts. Central sac 1.50 mm in diameter; round. Spermathecal ducts originate from base of central sac. Distribution. This species was previously recorded only from the montane regions of the southeastern quarter of Arizona, most extensively collected in the Chiricahua and Santa Rita Mountains. Its known range is extended to include the Pinos Altos Mountains in the Gila National Forest in New Mexico, the southwestern part of the Sierra Madre Occidental mountains in Nayarit, Mexico, and the northwestern part of the Sierra Madre del Sur in Jalisco, Mexico. It seems likely that this species covers the low altitude montane regions throughout this range (Fig. 3A), but is undercollected. Specimens examined.

Nesonana, gen. nov.

7jpe species. Nesonana young, sp. nov. EpmoloQ. Feminine. Gr., f., nesos: island + L., m., nanus: dwarf, referring to the small body size and Antillean island distribution. Diagnosis. These small-bodied have frons with gold pruinescence. This is one of the few cycloteline genera where the 8 ommatidia are of uniform size on the upper and lower halves. The notum is brown with lighter dorsocentral vittae and one pair of dorsocentral setae. The ventral and outer gonocoxal processes are parallel and oriented posteriorly (e.g. Fig. 80). The ventral gonocoxal process is weakly sclerotized and has smaller setae than the remainder of the gonocoxite. A strong sclerotized bridge between the gonocoxal apodeme and the parameral sheath of the aedeagus is present. The lateral edges of the dorsal apodeme of the aedeagus are divergent anteriorly (e.g. Fig. 117). Both ventral and ejaculatory apodemes (e.g. Fig. 117) are distinctly expanded anteriorly. The distiphallus is short. Synapomorphies. 8 ommatidia all the same size (character 7); lateral edges of dorsal apodeme divergent anteriorly (character 36); ventral apodeme expanded into dorso- ventrally flattened bulb anteriorly (character 39). Distribution. This genus is only known from the island of Hispaniola (Fig. 3A). Included species. Nesonana xenoverpa, sp. nov., and Nesonana youngi, sp. nov.

**Nesonana xenoverpa, sp. nov.

Etymology. Gr., m., xenos: stranger + L., f., verpa: penis; to be treated as a noun in apposition. Diagnosis. There is a second row of setae crossing the median occipital sclerite below the row of postocular setae. The epandrium is more or less parallel sided, with the posterolateral flanges folded medially under the hypoproct and cerci, which are both subequal in length. The dorsal apodeme of the aedeagus is longer than the ventral apodeme. The phallus is considerably more complex than in Nesonanayoungi, with dorsolateral wings folding over the top of the distiphallus. In the 0,the central sac is round. Autapomorphy.

Cyclotelus-group

Diagnosis. The female frons usually has reduced or modified pruinescence, ranging from matte or velutinous pruinescence to absence, fully exposing ground colour, as in many Ozodiceromyia. Most members of this group have an antennal first flagellomere that is cylindrical, with a subapical style set into a ventral pit on the first flagellomere. The maxillary palps vary in coloration and vestiture, but are rarely orange. On the upper and lower frons of the 9,setae are usually either lacking or are distributed in defined patches, but are only rarely scattered. The genal apex usually has a patch of different texture or colour from the remainder of the postgena and parafacial. Most members of this group (except Crebraseta and the basal members of Ozodiceromyia) also have a vertical line of reduced pruinescence from the wing base through the meron, encompassing the anepimeron, katepimeron, and meron. In the two largest genera within this group, Ozodiceromyia and Cyclotelus, the foretibia is often swollen relative to the other tibiae, and in Cyclotelus, the forebasitarsus is usually swollen relative the remainder of the foretarsus or other basitarsi. The notum usually has areas of reduced (exposing ground colour) or modified (matte or velutinous) pruinescence, especially on the lateral edges. The basal lobe of the costa usually has two distinct lines of setae on the dorsal surface leading into the inner and outer rows of costal setae, rather than being covered with scattered setae. The epandrium is either only covered with setae on the posterior half (e.g. Cyclotelus and Ozodiceromyia) or is almost entirely covered. The inner gonocoxal process usually (except for Cyclotelus) has apical setae (e.g. Figs 98, 100, and 92). The gonostylus usually lacks a subapical, lateral spur. Synapomorphies. Antenna1 first flagellomere cylindrical (character 4) (onion-shaped in Crebraseta and basal members of Ozodiceromyia); antennal style subapical, set into ventral pit on first flagellomere (character 5) (apical in Coleiana, Crebraseta, and basal members of Ozodiceromyia); 9 upper frons with velutinous pruinescence (character 8, state 3) (shiny black (state 2) in Ozodiceromyia and part of Cyclotelus; with matte pruinescence (state 1) in part of Cyclotelus); ? lower frons shiny black 178 S.

Epmology. L., nigos: black+f., copis: knife, referring to the colour and shape of the body; to be treated as a noun in apposition. Diagnosis. This is one of the few Cyclotelus-subgroup members with an apical antenna1 style set on the first flagellomere. This is the only known member of the tribe with a gena that does not protrude at least slightly in lateral view. The midbasitarsus is longer than tarsomeres 2-5 inclusive. This is the darkest coloured of all known Cyclotelini. The patches of matte pruinescence characteristic of most of the Cyclotelus- subgroup are dark brown in this species. Dorsocentral setae are absent. The wing membrane is darkened. This species is sexually dimorphic, more so than most therevids examined: in 9,the halteres and basal part of the wing are dark, while these are yellow in the d. The setae covering the gonocoxites and outer gonocoxal process are dense and uniform, as are the setae covering the epandrium, sternite 8, and tergite 8. The ventral apodeme of the aedeagus is thinned and sword-like. There is a dorsal, shelf-like projection over the distal distiphallus. Autapomorphies. Antenna1 style apical on first flagellomere (character 5, state 0); 9 lower frons with velutinous pruinescence (character 9, state 3); gena not protruding (character 13, state 0); tip of gena with same texture and colour as remainder of gena, postgena, occiput, and parafacial (character 14, state 0); basal distiphallus with dorsal shelf over distal distiphallus (character 43). 182 S.

Nomenclatural bookkeeping. The species crassicornis Williston ( 1886) was described Downloaded from https://academic.oup.com/zoolinnean/article-abstract/129/2/129/2682484 by guest on 24 June 2020 as a junior, primary homonym of the species of Bellardi (186 1). Cole (1965) erected the new name Dialineura willistoni Cole for the species of Williston, apparently not recognizing the fact that Williston himself (1908) had recognized his own error and erected the new name Thereva pachyceras Williston for his homonymous species. Therefore the name of Cole (1965) is considered an unjustified replacement name (but is the next available name for the species), and the name of Williston (1908) is formally recognized as the valid name, notwithstanding combination changes. Following is the current status for the species. Pallicephala pachyceras (Williston) Thereva crassicornis Williston, 1886: 293 (preoccupied by Thereva crassicornis Bellardi, 186 1: 88).

Diagnosis. The genal apex is enlarged, with a patch of darkened pruinescence, lacking pile (e.g. Fig. 35). The upper frons of the 6 usually has a diamond of brown or black matte pruinescence, and the lower frons is silver pruinose (e.g. Figs 34 and 38). The frons of the 9 usually has a well defined central patch of brown or black matte pruinescence (e.g. Fig. 35), and often has smaller patches laterally. The area Downloaded from https://academic.oup.com/zoolinnean/article-abstract/129/2/129/2682484 by guest on 24 June 2020 above this patch of matte pruinescence and below the ocellar tubercle may be shiny black and without pruinescence (e.g. Fig. 35), or can have matte pruinescence (e.g. Fig. 37). The area below the patch is silver pruinose. Parafacial pile is absent. The cleft of the prosternum lacks pile. The mesonotum usually has patches of black matte pruinescence dorsolaterally. Dorsocentral setae are absent. There are 1 or 2 supra-alar setae and 0-2 scutellar setae. The scutellum often has matte pruinescence. The anterolateral surface of the midcoxa has 1-2 macrosetae, and the lateral surface of the hindcoxa has 0-1 macrosetae. The foretibia is swollen and clavate (e.g. Fig. 45). The forebasitarsus is usually swollen relative to other tarsomeres (e.g. Fig. 45). Setae are widely distributed on tergite 8 (e.g. Fig. 53). This is the only member of the Cyclotelus-group that lacks apical setae on the inner gonocoxal process (e.g. Figs 102 and 106). A strong sclerotized bridge often attaches the gonocoxal apodeme and the parameral sheath of the aedeagus. Aedeagus as in Figures 140, 141, 142, 143, 144, and 145. The lateral edges of the dorsal apodeme of the aedeagus are divergent anteriorly. Synupomorphies. 9 upper frons with matte pruinescence (character 8, state 1); 9 lower frons with matte pruinescence (character 9, state 1); foretibia thickened distally and clavate (character 23); forebasitarsus swollen (character 24); midtarsomere 1 subequal in length to midtarsomeres 2-5 (character 25, state 0); common spermathecal duct <2 furcal lengths long (character 61, state 0); basal spermathecal duct wider than common spermathecal duct (character 63). Synapomorphies for Cyclotelus beckeri + Cyclotelus kroeberi: Midcoxa with one macroseta (character 2 1); hindcoxa lacking macrosetae (character 22); 1 pair of scutellar setae present (character 30); 1 pair of supra-alar setae present (character 3 1); ventral apodeme dorsoventrally flattened distally (character 38, state 0); inner gonocoxal process lacking apical setae (character 53).

The genal apex is enlarged and has a patch of darkened pruinescence and shortened, dark setae (e.g. Figs 25, 26, 27, 28, and 29). The frons, especially that of the 9, usually has some shiny black areas (e.g. Figs 25, 27, 28, and 29), but never has patches of matte pruinescence. The lower frons is sometimes bulging at the antenna1 insertion. Parafacial pile is sometimes present (e.g. Figs 24 and 25). The cleft of the prosternum has white pile. The scutum usually displays at least some ground colour, at least on the lateral edges; often with dorsocentral and/or median vittae. The katepisternum is pilose along the vertical median convex crest of the pleurite (e.g. Fig. 41). The foretibia is occasionally swollen and clavate. The epandrium (e.g. Figs 64,65, and 66) is typically parallel sided and lacks a dorsoventrally flattened posterolateral flange, but may be pointed. Setae cover only the posterior half of the epandrium, including the posterolateral corners. The gonostylus is usually expanded ventrally into a lobe, and the tip is usually curved up by 90’ (e.g. Fig. 109). The inner gonocoxal process is knob-like with distal setae (e.g. Figs 92, 94, and 96). The ventral gonocoxal process and the outer gonocoxal process are often present, and are variably setose or bare. The aedeagus and distiphallus are highly variable (e.g. Figs 128, 129, 130, 131, 132, 133, 134, 135). Synapomorphies. 9 upper frons with shiny black, pruinescence-free area (character 8, state 2) (subshiny in few species); setae covering less than posterior half of epandrium (character 47); outer gonocoxal process small or absent (character 50); gonostylus expanded ventrally into lobe (character 57). Distribution. This large and diverse genus has its greatest diversity in the southwestern U.S.A., California, and northern Mexico. Species range from Canada and throughout North America south into Venezuela and Ecuador (Fig. 3B). Specimens examined.

Nomenclatural bookkeeping. The species Psilocephala quadrimaculata Krober was described from one of the five all female syntypes of Psilocephala stigmaticalis Schiner (Krober, 191 1). Since that time, no lectotype has been designated to fix the identity of Psilocephala stigmaticalis. Because neither species has been extensively treated in the literature, and to provide nomenclatural stability, it seems prudent to designate the holotype of Psilocephala quadrimaculata as the lectotype of Psilocephala stigmaticalis, fixing Psilocephala quadrimaculata as a junior objective synonym of Psilocephala stigmaticalis.

BIOGEOGRAPHY

Methods of cladistic biogeography (Rosen, 1978; Nelson & Platnick, 198 1; Humphries & Parenti, 1986)were used to compare patterns of cycloteline cladogenesis and the vicariant events in geological history. Congruence between geological and phylogenetic histories provides corroboration that earth history has influenced cycloteline cladogenesis. The areas occupied by Cyclotelini (Fig. 3A-C) and used in this biogeographic analysis are as follows: Asia, North America, Central America, South America, Greater Antilles. Phylogenetic analysis resulted in several well defined genera with > 1 species being analysed, but for the most part, these biogeographic analyses were performed at the genus level. The only exception is the separation of the North and South American members of the genus Cyclotelus. Morphological evidence from more detailed studies in progress suggest that the two faunas are each monophyletic and warrant separate consideration. A resolved area cladogram was derived from the taxon-area cladogram (Fig. 4) using component analysis (Nelson & Platnick, 1981) via COMPONENT version 2.0 (Page, 1993), using the nearest-neighbour interchange algorithm in an heuristic search. Unfortunately, COMPONENT is limited in its ability to implement as- sumption 2 of Nelson & Platnick (198 1) (Page, 1993), although this currently seems to be the most realistic approach for dealing with dispersal (Morrone & Carpenter, 1994; Humphries, 1989) as it treats each geographical occurrence of a taxon separately. As Enghoff (1998) pointed out, by turning off the ‘map widespread associates’ option in COMPONENT, either assumption 1 (Nelson & Platnick, 198 1) PHYLOGENY AND BIOGEOGRAPHY OF CYCLOTELINE THEREVINAE 195 Ammothereva - Asia

In our case, all widespread taxa were in terminal postions (Fig. 4), and thus assumption 1 was effectively followed, allowing area relationships to be either mono- or paraphyletic relative to their widespread taxa. We minimized the optimality criterion ‘leaves added’, which is the number of branches added to reconcile both the taxon and area cladograms. Because counting the number of leaves added to reconcile a taxon cladogram with an area cladogram may overestimate the number of actual events (Page, 1989), we separately analysed the data minimizing the optimality criterion ‘losses,’ which takes into account, for example, that a single loss can account for absence of a larger taxon clade from an area or area clade, potentially resulting in several leaves added. To test for significant congruence between area and phylogenetic relationships (i.e. could the observed pattern have arisen by chance alone), the number of ‘leaves added’ was compared between a random set of 10 000 area cladograms (with labelled, rooted topologies) reconciled with the taxon cladogram (Page, 1993). The percentage of random trees that matched or had less than the number of ‘leaves added’ in the resolved area cladogram provided a measure of probability that the topology did not arise by chance alone. The random area cladograms were calculated using the ‘equiprobable’ model of random tree topology (Page, 1993). I96 S. D. GAIMAKI AND M. E. IRWIN

In assessing the probable ancestral area inhabited by early cyclotelines, several quantitative methods were employed. Bremer’s method of ancestral area analysis (Bremer, 1992) was used to compare possible gains versus losses of taxa in each area, respectively, within a ‘gain, no loss’ scenario starting from the root of the

taxon-area cladoLgram with no areas represented initially, and a ‘loss, no gain’ Downloaded from https://academic.oup.com/zoolinnean/article-abstract/129/2/129/2682484 by guest on 24 June 2020 scenario starting from the root of the taxon-area cladogram with all areas represented initially. In addition, we used Fitch optimization, according to the protocol of Liebherr (1988a) to deduce the ancestral area for the tribe. As per EnghoFs (1995) assesment, the descending phase (or downpass) of Fitch optimization is sufficient for estimating ancestral areas. Ronquist’s ( 1997) dispersal-vicariance analysis, as implemented by DIVA version 1.1 (Ronquist, 1996), was also an essential tool for quantitatively assessing the probable ancestral area for the tribe.

Earb histoly of Tiierevidae

Although still under analysis, Therevidae are thought to have a Jurassic, Pangaean origin, primarily based upon fossil evidence and present-day distributions of putatively primitive and derived members of the family. This follows the likely Triassic origin of the Brachycera (Woodley, 1989; Krzeminski, 1992), and the Jurassic origins of Asiloidea as displayed by fossil species representing a variety of asiloids (see Evenhuis, 1994), and by phylogenetic evidence, including that for Mydidae (Yeates & Irwin, 1996; Papavero & Wilcox, 1974) and Apioceridae (Yeates & Irwin, 1996). The Upper Jurassic species Rhagiophvrne bianalis Rohdendorf, 1964 (translation in 1974; illustration in Rohdendorf, 1991: 488, fig. 1091), which is represented by a series of well preserved specimens from the flyscoid deposits of the Karatau mountain ridge in southern Kazakhastan, is the earliest known fossil member of the Therevidae (Mostovski, 1998). In addition, the species Protomphrale marbnovi Rohdendorf, 1938 (illustration in Rohdendorf, 1991 : 49 1, fig. 1094), from the same deposits, represents the earliest known fossil member of the Scenopinidae (Rohdendorf, 1938; Mostovski, 1998), indicating that these two families were likely already differentiated by the Upper Jurassic.

Geological histoly

The geological history presented herein is a synthesis of pertinent portions of Briggs’ (1 995) review of biogeographical events, Smith, Smith, & Funnell’s (1 994) atlas of ancient coastlines, and Rosen’s (1976, 1985) hypotheses on the origins of the Greater Antilles. Despite the earlier origin of the family, biogeographical evidence herein suggests a Late Cretaceous origin for the Cyclotelini. By this time, 65-90 million years before present (Myr), high sea levels resulted in extensive epicontinental seas. Potentially important to cycloteline cladogenesis was the Mid-Continental Sea (Cox, 1974) separating Euramerica (i.e. eastern North America +western Europe) from West- america which formed a single continent with eastern Asia via the Beringian land bridge. This sea dried up in the Paleocene, but a north-south oriented mountain range (the present-day Rocky Mountains) through western North America remained an effective physical and climatic barrier to biotic movement (Frakes, 1979). In the PHYLOGENY AND BIOGEOGRAPHY OF CYCI,OTEI.INE THEREVINAE 197 late Cretaceous and early Paleogene, these northern latitudes were characterized by boreotropical to paratropical climates (Wolfe, 1975, 1977; Hsii, 1983). The Beringian land bridge was a route common to many groups, including (e.g. Matthews, 1979, 1980; Nalepa et al., 1997), plants, mammals, and lizards. Notable examples

of insect-plant congruence include several groups of Cerambycidae (Coleoptera) and Downloaded from https://academic.oup.com/zoolinnean/article-abstract/129/2/129/2682484 by guest on 24 June 2020 their host trees displaying this Asian-Westamerican pattern (Linsley, 1963). From the middle to late Paleogene (Eocene into Oligocene), the northern latitudes encountered a steady increase in humidity (Frakes, 1979) and precipitation (Wolfe & Hopkins, 1967), and a drop in temperatures (Frakes, 1979), all of which could have acted as vicariant barriers separating the North American and Asian faunas and floras. Further south, at the juncture of North and South America, Rosen (1976, 1985) proposed an archipelagic bridge, and Savage (1982) and Guyer & Savage (1986) proposed a solid land connection, linking the two continents through the Cretaceous- Paleogene boundary. This proto-Antillean archipelago, or isthmanian link, was on the eastern edge of the Caribbean plate which moved eastward in the early Eocene, to eventually become the present-day Greater Antilles. A second land mass followed on the western edge of the plate, becoming attached to southern North America. This Central American isthmus only reattached North and South America as recently as the Pliocene (less than 5 Myr). Perfit & Williams (1989) review geological events in the tectonic history of the Caribbean, noting that most evidence supports the continental origins of the Greater Antilles, which is also supported by the numerous biological examples in Woods (1989) and Liebherr (1988~).This differs from Briggs’ (1987, 1995) hypothesis that the archipelagic bridge remained in place to later form Central America, concluding that the Greater Antilles were oceanic in origin with subsequent colonization by over-water dispersal.

Taxon and area cladogram congruence

Early in cycloteline cladogenesis, there was a land bridge connecting Asia and Westamerica. At this time, western North America extended south through the proto-Antillean arc into South America. Five million years after the drying of the Mid-Continental Sea, the next major vicariant event was the eastward movement of the Caribbean plate. This resulted in the separation of the Greater Antilles from the mainland, the resulting separation of North from South America, and the subsequent attachment of present-day Central America into southern North America. This isthmus reattached North and South America less than 5 Myr. The resulting area cladogram of reviewed geological history is as follows: (Asia, (Greater Antilles, (South America, (Central America, North America)))), which is identical to the resolved area cladogram (Fig. 5) revealed by component analysis of the areas currently inhabited by members of the Cyclotelini, following assumption 1, and minimizing either optimality criterion, ‘leaves added’ or ‘losses’. In addition, the area cladograms of Rosen’s (1976) North American-Caribbean track and South American-Caribbean track (see Liebherr, 1988b, fig. 2a-b) are identical to the New World portion of the resolved area cladogram in Figure 5. The randomization tests strongly suggested that the area cladogram topology did not arise by chance alone. Of 10 000 random trees, only 99 trees (i.e.

the number of ‘leaves added’ found in the resolved area cladogram after reconciling with the phylogenetic cladogram (5 leaves added, with 5 area leaves). All three methods used for assessing the probable ancestral area for the Cyclotelini pointed to Asia as being their place of origin, with subsequent movement into the New World. Dispersal-vicariance analysis suggested 10 possible dispersal events to account for this Asian origin for the tribe. In comparing each major clade of the Cyclotelini with the area cladogram (Fig. 6A-C), all branches are explainable relative to their distributions (with some duplications), except for the unexplained presence of the North American contingent of Cyclotelus in the Greater Antilles (Fig. 6C). This points to potential problems associated with widespread taxa in biogeographical analyses.

Biogeographical synthesis

The Cyclotelini represents a diverse assemblage of genera with an apparently Laurasian distribution. Given the current distributions of taxa, the place of origin is likely to be in Asia. The plesiomorphic members of each major clade (i.e. Brevipema- group, Cyclotelus-subgroup, Ozodiceromyia-subgroup) are Asian, so it is likely that each of the groups independently moved from Asia and diversified more fully in the New World. The other alternative is that the tribe originated in the New World, with the plesiomorphic members each moving to Asia through Beringia. This latter possibility is not supported by the analytical methods invoked for assessing ancestral areas. Despite the likely Asian origin for the tribe, there is a relative scarceness of Asian taxa, and more complex distributional patterns are displayed by the New World cycloteline fauna. The lack of cycloteline taxa in Africa, Australia, or Chile suggests that their origin was not Gondwanan, as could be otherwise suggested by the current distribution of the genera Anolinga and Coleiana in southeastern Brazil. The general absence of even primitive members of the tribe from western Europe, and the paucity of taxa and the lack of more plesiomorphic taxa from eastern North America suggests that the cyclotelines diversified in the New World after the late Cretaceous separation of Euramerica and Westamerica by the Mid-Continental Sea. After the Mid-Continental Sea dried up in the Paleocene, few groups (e.g. part of Cyclotelus and few more derived members of Ozodiceromyia) moved eastward; others Downloaded from https://academic.oup.com/zoolinnean/article-abstract/129/2/129/2682484 by guest on 24 June 2020 200 S. D. GAIMARI AND M.E. IRWIN were likely prevented by the north-south oriented mountain range running through western North America. The Beringian land bridge linked North America and Asia. Climatic characteristics, which varied considerably through this geological time, were likely the vicariance

inducing factors separating the North American from Asian cycloteline faunas. Downloaded from https://academic.oup.com/zoolinnean/article-abstract/129/2/129/2682484 by guest on 24 June 2020 Current New World distributions were profoundly affected by the early Eocene eastward migration of the archipelagic or isthmanian bridge between North and South America, providing support for Rosen’s (1976, 1985) hypothesis favouring the continental origin of the Greater Antilles. The widespread North American contingent of Qclotelus occurring on these islands, however, is difficult to explain in the context of vicariance. Many other groups of insects, and numerous non-insect examples, share some of the vicariant patterns found in the present study, including several groups of Antillean Trichoptera (Flint, 1976, 1978; Hamilton, 1988), the dipteran families Drosophilidae (Grimaldi, 1988) and Keroplatidae (Matile, 1990), and the coleopterous subfamily Scarabaeinae (Scarabaedidae) (Halffter, 1974).

CONCLUSIONS

This study provides the first phylogenetic classification of a monophyletic, supra- generic grouping within the subfamily Therevinae. Using the long hypothesized relationship between Ozodiceromyia and Cyclotelus as a starting point, numerous generic level taxa, both described and undescribed, were considered for inclusion within this putatively monophyletic group. In the end, a large set of synapomorphic characteristic were found to support a monophyletic Cyclotelini, which is currently an assemblage of 10 genera spanning the Americas and extending into Middle, Far East, and Southeast Asia. With time and further collecting efforts, the faunas of South America (especially the underexplored parts of Brazil) and eastern Asia will probably yield additional cycloteline genera, and will likely add further species to the existing genera.
