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. (0.) izever~na~z~zi(western slopes of Volcan Irazu, Costa Rica.); P. (0.) tz~rnbowi(near the trailhead of the Continental Divide Trail, Chiriqui Province, Panamti); and P. (0.) lamzcrallu (Parque Nacional La Muralla, Olancho Department, Honduras). In Plzloeoxena (Oenaplzelox), the following 4 new species are described: P. (0.)totontepec (16.6 km south of Totontepec, State of Oaxaca, Mkxico); P. (0.) brooksi (El Guisayote, 24 lim east of Ocotepeque, Ocotepeque Department, Honduras); P. (0.) aslzei (Parque Nacional La Muralla, 14km northof La Union. Olancho Department, Honduras); ancl P. (0.) viridis (El Guisayote, 24li1n east of Ocotepeque, Ocotepeque Department, Honduras). In Plzloeoxena (s. str.), the following 2 new species are described: P. (P.) rzitida (51.5 km south ofValle Nacional, State of Oaxaca, Mkxico); and P. (P.) obscura (vicinity of Coscornatepec, State of Veracruz, Mexico). Based on study of the holotype, Plzloeoxena biz~ndataSteinheil is includedin the subgenus Plzloeoxena. The status of P. (P.)picta batesi Ball is changed from subspecies to species, based on new locality data indicating extensive range overlap of P. picta (se~zszclato) and P. butesi. New locality records are provided for the following previously described species of Plzloeoxe~za:P. (Tacuna) lzerculeano Ball; P. (Oclzropisus) concolor Ball (substantial range extension in western NIkxico); P. (Ockropiszes) cuzedalis Bates; P. (Oe~zaphelox)newtoni Ball (a second record); P. (Oe~zaplzelox)uizdata Chaucloii-; P.

(s. str.)picta fi.a~ziaeBall; P. (s. str.)picta ze~zicolorChaudoir; P. (s. str.)pictapictu Chaudoii*;P. (s. str.)pictaapicalis Ball; and P. (s. str.) batesi Ball. 2 Volume 14, No. 1-3, March-September, 2000, INSECTA MUNDI Two lnonobasic species and 1dibasic species of the pantropical genus Catascopus Kirby are recognized. 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). Both species groups and both subgroups are represented in South America and Middle America by precinctive species. New locality cords for Er~rycoler~spoecilopterus Buquet extend its range to northern Argentina, the southernlnost area for the genus. The sole genus in the Western Heinispliere of the Pericalus genus-group, Coptodei-a Dejean, anothei- pantropical genus, is represented by 44 species. New locality records are recorded for the following: C. elorzguta Putzeys; C. schurcini Cha~~doi~;C. inegalops Bates (range extellsioll into Middle America, froin South America); C. clzainpioizi Bates; C. versicolor Bates; C. rzigrosti-iatu (Reiche); C. lineata (Bates); C. traizsuersa (Reiche); C. reluceizs Bates; C. festiva Dejean; C. ae~~eorzifaBates; C. tripartita Chaucloir; C. crpreotii~ctaBates; C. chalcites Bates; C. uc~~tiper~izisBuquet (all recently acquired males were
