Ball Department of Biological Sciences University ofAlberta Edmonton,Alberta T6G 2E9 Canada Abstract: A taxonomic 'eview of the lebiine subtribe Pericalina in the Western Hemisphere, this paper includes a treatnlent of the genus-groups, a key to the genera, keys to subgenera, species gro~~ps,and species of each polybasic genus, descriptions of new species and new subgenera, new locality records for previously described species, re-ranliings, and new synonymy. In total, 11 1species and subspecies are treated, 26 of which are described as new. A review of the taxonoinically useful mandibular structure, based on stereo-electron (SEM) photographs, requires changes in previously published names of various structures. Areview of adhesive vestiture on the front tarsi of inales shows 3 different types each characteristic of different taxa. In the eastern Brazilian montane genus Oreodicastes Maindron, 5 species are recognized, of which 3 are described as new (with type localities): 0. aeacus and 0. rni~zos(Campos de JordBo, State of SBo Paulo, Brazil); and 0. rlzada71zantlzres (Serra do Cara~a,State of Minas Gerais, Brazil). In the wide-ranging genus Ste7zognatlzzcs Chaudoir, 19 species are recognized, and arranged in the following subgenera: the rnonobasic Proste7zog1zatlzns,new subgenus (type species S. oizorei, new species); the nlonobasic Gnathostenus new subgenus (type species S. de1ztife7noratus,new species); the polybasic Stenog~zatlzus(s. str.) (type species A~zclzo~nenres~nelaizarius Dejean), with 16species; and the monobasic PT-istolo~nusChaudoir (type species S. dentifer Chaudoir). Steizog~zatlzrcscaye~zne~zsis Buquet 1835 is a no7ne7z dz~bium.The species of subgenus Stenognatlzzcs are arranged in 4 species groups: the S. stricticollis species group, with 4 species; the monospecific S. procerus species group; the S. nigropiceus species group (including Plzloeotherates Bates and Ferus Chaudoir), with 6 species; and the S. ~nela~zariusspecies group, with 5 species. New species (with type localities) described herein: S. (Pr-oste~zog~zatlzzes)onorei (West of Chiriboga, Pichincha Province, Ecuador); S. (G~zatlzoste7zzes) dentife~noratzes("Colombia"); S. (se~zsustricto, nigropicezes group) plau7nanni (Nova Teutonia, State of Santa Catarina, Brazil); and S. (senszc stricto, nigropiceus group)jauja (Sani Beni, Jauja PI-ovince, Departamento Junin, Peru). Descriptions and new locality 'ecords are reported for the species known previously. For the principally Middle Ainerican genus Plzloeoxena Chaudoir, the new monobasic subgenus Oxeplzloena is described: type species, P. tzcrrialba, new species (Turrialba, Cartago Province, Costa Rica). Ochropisus Bates is included as a subgenus in Phloeoxena, ancl the following 5 new species (with type localities) are described: P. (0.) davidsoni (15 lim. northwest of El Paraiso, State of Guerrero, Mkxico);P. (0.) Izenryi (northeast slope ofVolcan Tacanti, State of Chiapas, Mkxico); P.

New synoliynly is as follows: C. obsc~~roviridisChevrolat 1835 = C. i~zexicaizusChaudoir 1877 = C. arzgr~licollisBates 1878; C. validr~sChaudoir 1854 = C. guateinaler~sisBates 1883; C. brasilieizsis Dejean 1825 includes the South American C. b. brasilieizsis (new status) = C. cayeizrzensis Chaudoir 1872 and the Middle American C. b. clzoiztuleizsis Bates 1878 (new status). New locality records for the 3 Middle American species, C. obsc~~rouiridis, C. ualidus, and C. b. clzorztaleizsis show extensive range overlap. Nonetheless, C. ualid~ssseeins to be isolated altituclinally from the other 2 species. Catascopus b. brasilieizsis is a rather varied species and wide-ranging in South America, from the Brazilian Atlantic Forest to the Upper Ainazon Basin, in Peru and Ecuador. The monospecific Chilean-Argentinian genus Catascopellzss Stralieo (type species C. ci-assiceps Straneo) is relnoved from the Soinotrichus genus-group and placed in the monogeneric Catascopell~~sgenus-group, primarily on the basis of divergence in the combination of structural details of the mouthparts and adhesive vestiture of the front tarsi of males. The Catascopell~~sgenus-group in many of its diagnostic features is much lilie the Tlz~1reopterr~sgenus-group, but males of the 2 groups differ from one another in the adhesive vestiture of the fore tarsi. The linown geographical range of C. cmssiceps is extended from eastern Chile to western Argentina. The precinctive Neotropical E~sr,ycoler~sgenus-group, includingonly Lelis Chaudoir alidEz~i-ycolez~sChaudoir, is re~haracte~ized,with special reference to details of the mandibles and labium. The 4 valid species of Lelis, (wit11 syllonyms of the valid names) follow: the South American L. obt~~saizgzila(Chaucloir) 1852; the South American L. quadi.isignata (Buquet) 1834 = L. polygoiza (Bates), 1869 = L. bifasciata Chaudoir 1869, new synonym = L. latipenizis (Bates) 1869, new synonym; the South American-Middle American L. rr~tila(Bates) 1869 = L. viridiperzizis Clzaz~doir1869 = L. cyu~~ipennisSteinheil 1875, new synonyln = L. insculpta (Bates) 1893, new synonym; and the Middle American L. bicolor Clza~sdoir1869. Putative adelphotaxon relationships, based on structural details of adults, are: L. obt~~saizgrsla(L. qr~adrisigizata(L. rz~tila+ L. bicoloi-)). Based on color pattern, the 8 species of the genus Ez~rycole~~sChaudoir are arranged in 2 species groups: the E. poecilopterzrs group with 2 species; and the E. tredecii?zpr~izctatusgroup, with 6 species. The species of the latter species group are arranged in2 subgroups,theseptei~zplagiatussubgroup, with 2 species, and the tredeci~n~~uizctat~~s subgroup, with 4 species, including E. erwiizi, new species (Estaci6n Sirena, Playa Sirena, Puntarenas, Costa Rica).

    Pacific Insects 5 (4) : 837-847 December 30, 1963 ANISODACTYLUS BINOTATUS FABR., A CARABID BEETLE NEW TO NEW ZEALAND, AND A REVIEW OF THE EXOTIC CARABID FAUNA By R. L. C. Pilgrim DEPT, OF ZOOLOGY, UNIVERSITY OF CANTERBURY, NEW ZEALAND Abstract: Anisodactylus binotatus Fabr. 1787 (Col.: Carabidae), an introduced species now established in Canterbury (South Island), New Zealand, is reported for the first time. The literature respecting other carabids sometimes recorded as introduced is reviewed; Ago- nochila binotata (White, 1846), Agonum submetallicum (White, 1846), Hypharpax australasiae (Dejean, 1829) and Pentagonica vittipennis Chaudoir, 1877 are shown to be better considered as endemic to the Australia - New Zealand area. Other species are classed as either native to New Zealand, clearly introduced though not all established, or of doubtful occurrence in New Zealand. Introduction: The Carabidae of New Zealand are predominantly endemic species, but a small number of exotic species has been recorded. This paper reports a further introduc­ tion to the carabid fauna of this country and concludes with a survey of recorded exotic Carabidae in New Zealand. Specimens of the newly-recorded species were collected in domestic gardens in Christ­ church, and were included in a collection sent for identification to Dr. E. B. Britton, British Museum (Nat. Hist.), who kindly drew the writer's attention to the fact that they were so far unreported from New Zealand. Description of adult (from New Zealand specimens) Fig. 1. Anisodactylus binotatus Fabricius, 1787 Color: Head, pronotum, elytra and femora black; tibiae and tarsi light brown to red- black ; palps and antennal segments 1-2 brown, remainder of antennae black; leg spines red-brown; head with small red spot on frons between eyes.

  • A Genus-Level Supertree of Adephaga (Coleoptera) Rolf G
    ARTICLE IN PRESS Organisms, Diversity & Evolution 7 (2008) 255–269 www.elsevier.de/ode A genus-level supertree of Adephaga (Coleoptera) Rolf G. Beutela,Ã, Ignacio Riberab, Olaf R.P. Bininda-Emondsa aInstitut fu¨r Spezielle Zoologie und Evolutionsbiologie, FSU Jena, Germany bMuseo Nacional de Ciencias Naturales, Madrid, Spain Received 14 October 2005; accepted 17 May 2006 Abstract A supertree for Adephaga was reconstructed based on 43 independent source trees – including cladograms based on Hennigian and numerical cladistic analyses of morphological and molecular data – and on a backbone taxonomy. To overcome problems associated with both the size of the group and the comparative paucity of available information, our analysis was made at the genus level (requiring synonymizing taxa at different levels across the trees) and used Safe Taxonomic Reduction to remove especially poorly known species. The final supertree contained 401 genera, making it the most comprehensive phylogenetic estimate yet published for the group. Interrelationships among the families are well resolved. Gyrinidae constitute the basal sister group, Haliplidae appear as the sister taxon of Geadephaga+ Dytiscoidea, Noteridae are the sister group of the remaining Dytiscoidea, Amphizoidae and Aspidytidae are sister groups, and Hygrobiidae forms a clade with Dytiscidae. Resolution within the species-rich Dytiscidae is generally high, but some relations remain unclear. Trachypachidae are the sister group of Carabidae (including Rhysodidae), in contrast to a proposed sister-group relationship between Trachypachidae and Dytiscoidea. Carabidae are only monophyletic with the inclusion of a non-monophyletic Rhysodidae, but resolution within this megadiverse group is generally low. Non-monophyly of Rhysodidae is extremely unlikely from a morphological point of view, and this group remains the greatest enigma in adephagan systematics.

  • Vegetation Cover Drives Arthropod Communities in Mediterranean/Subtropical Green Roof Habitats
    sustainability Article Vegetation Cover Drives Arthropod Communities in Mediterranean/Subtropical Green Roof Habitats Ibrahim N. A. Salman * and Leon Blaustein Department of Evolutionary and Environmental Biology, Institute of Evolution, Faculty of Natural Sciences, University of Haifa, Haifa 3498838, Israel; [email protected] * Correspondence: [email protected] Received: 24 October 2018; Accepted: 13 November 2018; Published: 15 November 2018 Abstract: Worldwide, urban areas are expanding both in size and number, which results in a decline in habitats suitable for urban flora and fauna. The construction of urban green features, such as green roofs, may provide suitable habitat patches for many species in urban areas. On green roofs, two approaches have been used to select plants—i.e., matching similar habitat to green roofs (habitat template approach) or identifying plants with suitable traits (plant trait approach). While both approaches may result in suitable habitats for arthropods, how arthropods respond to different combinations of plants is an open question. The aim of this study was to investigate how the structural complexity of different plant forms can affect the abundance and richness of arthropods on green roofs. The experimental design crossed the presence and absence of annuals with three Sedum sediforme (Jacq.) Pau (common name: stonecrops) treatments—i.e., uniformly disrupted Sedum, clumped disrupted Sedum, and no Sedum. We hypothesized that an increased structural diversity due to the coexistence of different life forms of plants on roofs is positively related to the abundance and richness of arthropods. We found that arthropod abundance and richness were positively associated with the percent of vegetation cover and negatively associated with substrate temperature.

    Archival copy: for current recommendations see http://edis.ifas.ufl.edu or your local extension office. EENY673 A Hister Beetle Carcinops pumilio (Erichson) (Insecta: Coleoptera: Histeridae: Dendrophilinae: Paromalini)1 Matthew R. Moore and Phillip E. Kaufman2 Introduction Taxonomy and Synonymy The hister beetle Carcinops pumilio (Erichson) is a predator The taxonomic history of this hister beetle is complicated and natural enemy of the pestiferous house fly, Musca and marked by confusion of the scientific names Carcinops domestica Linnaeus (Figure 1). Carcinops pumilio has a pumilio (Erichson) and Carcinops quattuordecims- broad world distribution and is associated with wild bird triata (Stephens) that stems from uncertainty surrounding nests and bat guano piles. This species’ ability to limit house the publication dates of these. Carcinops pumilio was fly populations in poultry production settings led to its originally described in the genus Paromalus from a series study as an augmentative biological control agent (Bills of specimens collected in Spain, North America, and Egypt 1973; Kaufman et al. 2002a, 2002b; Achiano and Giliomee (Erichson 1834). The species was transferred to the new 2005). genus Carcinops by Marseul (1855), and the classification of the species in the genus Carcinops was accepted by most subsequent historical authors (Marseul 1862; Gemminger and Harold 1868; Ganglbauer 1899; Lewis 1905; Reitter 1909; Kolbe 1910; Scott 1913; Bickhardt 1910, Bickhardt 1917; Blackwelder 1944). However, Stephens’s (1835) name Carcinops quattuordeci- mstriata, described from England and referring to the same organism, was considered the senior synonym (i.e., it was thought to be the older name) and the valid name for the species because it was thought to have been described before Carcinops pumilio (Erichson).

    30 THE GREAT LAKES ENTOMOLOGIST Vol. 42, Nos. 1 & 2 An Annotated Checklist of Wisconsin Ground Beetles (Coleoptera: Carabidae) Peter W. Messer1 Abstract A survey of Carabidae in the state of Wisconsin, U.S.A. yielded 87 species new to the state and incorporated 34 species previously reported from the state but that were not included in an earlier catalogue, bringing the total number of species to 489 in an annotated checklist. Collection data are provided in full for the 87 species new to Wisconsin but are limited to county occurrences for 187 rare species previously known in the state. Recent changes in nomenclature pertinent to the Wisconsin fauna are cited. ____________________ The Carabidae, commonly known as ‘ground beetles’, with 34, 275 described species worldwide is one of the three most species-rich families of extant beetles (Lorenz 2005). Ground beetles are often chosen for study because they are abun- dant in most terrestrial habitats, diverse, taxonomically well known, serve as sensitive bioindicators of habitat change, easy to capture, and morphologically pleasing to the collector. North America north of Mexico accounts for 2635 species which were listed with their geographic distributions (states and provinces) in the catalogue by Bousquet and Larochelle (1993). In Table 4 of the latter refer- ence, the state of Wisconsin was associated with 374 ground beetle species. That is more than the surrounding states of Iowa (327) and Minnesota (323), but less than states of Illinois (452) and Michigan (466). The total count for Minnesota was subsequently increased to 433 species (Gandhi et al. 2005). Wisconsin county distributions are known for 15 species of tiger beetles (subfamily Cicindelinae) (Brust 2003) with collection records documented for Tetracha virginica (Grimek 2009).

  • Distribution and Structure of Arthropod Communities in Relation to Resource Patches and Spatial Scale in Dryland Woodland Ecosystems
    Distribution and structure of arthropod communities in relation to resource patches and spatial scale in dryland woodland ecosystems Alan B. C. Kwok Evolution and Ecology Research Centre School of Biological, Earth and Environmental Sciences University of New South Wales Sydney, NSW, 2052 Australia PhD thesis March 2012 THE UNIVERSITY OF NEW SOUTH WALES Thesis/Dissertation Sheet Surname or Family name: Kwok First name: Alan Other name/s: Bing Choong Abbreviation for degree as given in the University calendar: PhD School: Biological, Earth and Environmental Faculty: Science Sciences Title: Distribution and structure of arthropod communities in relation to resource patches and spatial scale in dryland woodland ecosystems Abstract 350 words maximum: (PLEASE TYPE) In dryland ecosystems, resources such as water, nutrients and habitat are concentrated into discrete patches. This resource concentration occurs at fine (e.g. around trees, grasses or logs) and broad (e.g. habitat remnants within an agricultural matrix) scales. Arthropods, which include insects, spiders, and a range of other invertebrates, provide a range of critical ecosystem functions in drylands. Arthropods may be particularly sensitive to changes in resource concentration given their small size and habitat requirements. Limited research, however, has examined how arthropods respond to changes in resource concentration across different spatial scales. This thesis examines how the concentration of resources affects the distribution and structure of arthropod communities at multiple spatial scales in south-eastern Australia. Chapter 1 provides an overview of resource patchiness in arid and semi-arid ecosystems, and describes how it is known to affect the biota. Chapters 2 to 4 investigate how the fine-scale distribution of resources (plants, and plant-associated patches) affects the distribution and composition of arthropod communities at local (plant-plant) scales.
