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 ) tachira , new species Fig. 36–40 , 87 Helicopsyche tachira has a unique hourglass­shaped gonocoxite in lateral view. Tergum X is undivided apically as in H . cubana Kingsolver , H . guadeloupensis Malicky , H . laneblina , new species , H . molesta Botosaneanu , H . ramosi Flint , and H . sigillata Botosaneanu & Flint , but in H . tachira tergum X is pointed, while it is rounded in the other species. Male. Head: Antennal scape about 1.5x longer than eye diameter, with pale yellowish setae. Eyes small. Maxillary palp segments equally long, each longer than eye diameter; covered by dark setae. Cephalic warts small, oval, about 0.8x as long as eye diameter, with dark golden and black setae. Forewing dark golden brown, length 5.9 mm . Sternum VI process absent. FIGURES 36–40. Helicopsyche tachira , new species , holotype. 36—male genitalia, lateral; 37— male genitalia, dorsal; 38—male genitalia, ventral; 39—phallus, lateral; 40—phallus, ventral. Male genitalia ( Fig. 36–40 ). Segment IX, in lateral view ( Fig. 36 ), with anterior lobe narrowly ellipsoid, oriented anterodorsally, present dorsolaterally; anterodorsal margin concave; anteroventral margin widely concave; in dorsal view ( Fig. 37 ), with inner margin triangular; in ventral view ( Fig. 38 ), without posterior process; lateral apodeme present as anteriorly oriented, slightly sigmoid line ( Fig. 36 ) fading before reaching anterior margin; sub­marginal line absent; tergal transverse apodeme absent; sternal transverse apodeme absent. Segment X, in lateral view ( Fig. 36 ), nearly straight, oriented posteroventrad; slightly tapering before narrow apex, apex slightly pointed; in dorsal view ( Fig. 37 ), about parallel­sided proximally to triangular apex, apex without notch; with about 9 pairs of about equally long, weak megasetae in longitudinal group starting at proximal half. Superior appendage ( Fig. 36 ) club­shaped in lateral view, oriented posterolaterally ( Fig. 37 ). Primary branch of gonocoxite, in lateral view ( Fig. 36 ), generally narrowing at midlength, dorsal margin undulate; apex rounded in lateral and dorsal views ( Fig. 36, 37 ); central part of primary branch slightly wider than height of central part of tergum X ( Fig. 36 ); anterodorsal margin concave, smooth; posteroventral margin concave; inside of primary branch strongly widening medially into pointed process bearing 2 megasetae ( Fig. 37 ); basimesal lobe rounded apically, slightly protruding primary branch in lateral view ( Fig. 36 ); with slightly convex, apically diverging median margins ( Fig. 38 ); with nearly 30 short megasetae on dorsal margin; basal plate, in lateral view ( Fig. 36 ), short, thick, slightly bent ventrally, apex truncate; in ventral view ( Fig. 38 ), narrowly pointing anteriorly. Phallus, in lateral view ( Fig. 39 ), with anterior 1/3 nearly straight, strongly bent ventrad at midlength, dorsal margin undulating; ventral margin sharply curved; anterior 1/5 nearly 2x broader than its central part ( Fig. 39 ); in ventral view ( Fig. 40 ), phallobase absent; endotheca slightly produced; sperm channel divided into short, thick posterior and slender anterior parts; sclerotized posteroventral part wide.
