Helicopsyche (Feropsyche) tachira , new species
Fig. 36–40 View FIGURES 36 – 40 , 87 View FIGURE 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.
Male genitalia ( Fig. 36–40 View FIGURES 36 – 40 ). Segment IX, in lateral view ( Fig. 36 View FIGURES 36 – 40 ), with anterior lobe narrowly ellipsoid, oriented anterodorsally, present dorsolaterally; anterodorsal margin concave; anteroventral margin widely concave; in dorsal view ( Fig. 37 View FIGURES 36 – 40 ), with inner margin triangular; in ventral view ( Fig. 38 View FIGURES 36 – 40 ), without posterior process; lateral apodeme present as anteriorly oriented, slightly sigmoid line ( Fig. 36 View FIGURES 36 – 40 ) fading before reaching anterior margin; submarginal line absent; tergal transverse apodeme absent; sternal transverse apodeme absent. Segment X, in lateral view ( Fig. 36 View FIGURES 36 – 40 ), nearly straight, oriented posteroventrad; slightly tapering before narrow apex, apex slightly pointed; in dorsal view ( Fig. 37 View FIGURES 36 – 40 ), 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 View FIGURES 36 – 40 ) clubshaped in lateral view, oriented posterolaterally ( Fig. 37 View FIGURES 36 – 40 ). Primary branch of gonocoxite, in lateral view ( Fig. 36 View FIGURES 36 – 40 ), generally narrowing at midlength, dorsal margin undulate; apex rounded in lateral and dorsal views ( Fig. 36, 37 View FIGURES 36 – 40 ); central part of primary branch slightly wider than height of central part of tergum X ( Fig. 36 View FIGURES 36 – 40 ); anterodorsal margin concave, smooth; posteroventral margin concave; inside of primary branch strongly widening medially into pointed process bearing 2 megasetae ( Fig. 37 View FIGURES 36 – 40 ); basimesal lobe rounded apically, slightly protruding primary branch in lateral view ( Fig. 36 View FIGURES 36 – 40 ); with slightly convex, apically diverging median margins ( Fig. 38 View FIGURES 36 – 40 ); with nearly 30 short megasetae on dorsal margin; basal plate, in lateral view ( Fig. 36 View FIGURES 36 – 40 ), short, thick, slightly bent ventrally, apex truncate; in ventral view ( Fig. 38 View FIGURES 36 – 40 ), narrowly pointing anteriorly. Phallus, in lateral view ( Fig. 39 View FIGURES 36 – 40 ), 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 View FIGURES 36 – 40 ); in ventral view ( Fig. 40 View FIGURES 36 – 40 ), phallobase absent; endotheca slightly produced; sperm channel divided into short, thick posterior and slender anterior parts; sclerotized posteroventral part wide.
