Thirteen new species and new distribution records of Helicopsyche (Feropsyche) Johanson from Venezuela (Trichoptera: Helicopsychidae) Author Johanson, Kjell Arne Author Holzenthal, Ralph W. text Zootaxa 2004 711 1 40 journal article 10.5281/zenodo.169460 c6b6aaea-4e91-4f23-b4bd-c80a4f676e13 1175­5326 169460 5403C332-6597-48D3-BD4D-7AD6D4CDC2CA Helicopsyche ( Feropsyche ) linabena , new species Fig. 67–71 , 87 In lateral view, the shape of the gonocoxite and tergum X makes this species very similar to H . hageni . The two species can be discriminated by the absence of a distinct basimesal lobe and thicker phallus in H . linabena , new species . Male. Head: Antennal scape about as long as eye diameter. Maxillary palp segments equally long, each segment as long as eye diameter. Cephalic warts not visible. Forewing dark golden­brown, with three small silver­colored spots, length 2.9 mm . Sternum VI process absent. FIGURES 67–71. Helicopsyche linabena , new species , holotype. 67—male genitalia, lateral; 68—male genitalia, dorsal; 69—male genitalia, ventral; 70—phallus, lateral; 71—phallus, ventral. Male genitalia ( Fig. 67–71 ). Segment IX, in lateral view ( Fig. 67 ), with anterior lobe widely triangular, oriented anteriad, located dorsolaterally on segment; anterodorsal margin nearly straight, anteroventral margin shallowly concave; in dorsal view ( Fig. 68 ), with inner margin hyperboloid; in ventral view ( Fig. 69 ), with minute posterior process; lateral apodeme short, extending slightly anteriorly of midlateral, transverse sternal process present, transverse tergal apodeme absent. Segment X, in lateral view ( Fig. 67 ), curving posteroventrad; slightly tapering along its length toward rounded apex; in dorsal view ( Fig. 68 ), proximally parallel­sided, distally rounded toward apex; apex with V­shaped notch ( Fig.68 ); with about 9 pairs of about equally long megasetae in longitudinal group starting at proximal half on segment ( Fig. 67 ). Superior appendage ( Fig. 67 ) irregularly club­shaped in lateral and dorsal views ( Fig. 67, 68 ); nearly straight. Primary branch of gonocoxite, in lateral view ( Fig. 67 ), generally curving posteriorly, slightly widening distally along its length; apex rounded in lateral view, hooked in dorsal view ( Fig. 67, 68 ); central part of primary branch about 2x as wide as height of central part of tergum X ( Fig. 67 ); anterodorsal margin nearly straight, smooth; posteroventral margin shallowly concave, smooth; basimesal lobe minute, slightly proceeding primary branch in lateral view, forming rounded plate in ventral view ( Fig. 69 ) and armed with about 8 dorsal megasetae ( Fig. 67, 69 ); with smooth, slightly diverging median margins; basal plate, in lateral view ( Fig. 67 ), nearly straight, apex narrowly rounded; in ventral view ( Fig. 69 ), triangular, apically rounded. Phallus, in lateral view ( Fig. 70 ), proximally nearly straight; ventral margin strongly bent ventrad at distal 1/3; anterior 1/5 more than 1.5x broader than its central part ( Fig. 70 ); in ventral view ( Fig. 71 ), tapering toward proximal 1/3; phallobase forms small lateral triangular ( Fig. 71 ); endotheca slightly produced into dorsodistal lobe ( Fig. 70 ); sperm channel divided into thick posterior and slender anterior parts; sclerotized posteroventral part wide ( Fig. 70 ). Holotype male: VENEZUELA : T.F.A. [Territorio Federal Amazonas = Estado Amazonas]: Camp IV, Cerro de la Neblina, 0°58'N , 65°57'W , 760 m , 15–18.iii.1984 , O.S. Flint, Jr. ( NMNH , pinned). Paratypes : same data as holotype1 male , 5 females ( NMNH ). Distribution. Venezuela (Amazonas). Etymology. The name linabena is an anagram of the name of the type locality, Cerro de la Neblina. The name is to be treated as a noun in apposition.
