description: Helicopsyche (Feropsyche) camuriensis, new species
Fig. 22–28, 87
Helicopsyche caligata Flint has a club­shaped gonocoxite similar to that of H. camuriensis, but the new species is unique in having a larger anterior lobe on segment IX, the presence of large basimesal lobes on the gonocoxite, and the numerous setae along the dorsal margin of tergum X.
Male. Head: Antennal scape about 2/3 as long as eye diameter. Maxillary palp segments equally long, each segment as long as eye diameter. Cephalic warts round, small, strongly convex, about 1/3 as long as eye diameter, with pale grey and golden brown setae. Forewing pale golden brown, length 3.8–4.1 mm. Sternum VI process (Fig. 22, 23) about 1/3 its segment length, covered by microtrichiae; nearly straight and slightly tapering in lateral view (Fig. 22), oriented posteroventrally; narrowing along its length in ventral view (Fig. 23); apex bearing ventral lamellae (Fig. 23).
Male genitalia (Fig. 24–28). Segment IX, in lateral view (Fig. 24), with anterior lobe hyperboloid, oriented anteriad, present midlaterally; anterodorsal margin nearly straight; anteroventral margin shallowly concave; in dorsal view (Fig. 25), with inner margin widely hyperboloid; in ventral view (Fig. 26), with minute posterior process; lateral apodeme present as anteriorly oriented, nearly straight line (Fig. 24), fading before reaching anterior margin; sub­marginal line absent; tergal transverse apodeme present; sternal transverse apodeme present. Segment X, in lateral view (Fig. 24), oriented posteroventrad, nearly straight along its length; dorsally undulate; slightly tapering along its length, apex widely rounded; in dorsal view (Fig. 25), slightly narrowing apically, apex without notch; with about 14 pairs of about equally long megasetae in group starting at proximal half. Superior appendage (Fig. 24) tubular, apex slightly club­shaped, oriented posterolaterally. Primary branch of gonocoxite, in lateral view (Fig. 24), with proximal half about equally broad, strongly widening to club­shaped distal half, with undulate dorsal margin; apex weakly produced, oriented posteriorly; central part of primary branch slightly narrower than height of central part of Tergum X (Fig. 24); anterodorsal margin nearly straight, smooth; posteroventral margin nearly straight at proximal half; basimesal lobe large, protruding primary branch, apically widely rounded in lateral view (Fig. 24), tubular in ventral view (Fig. 26), with nearly straight, sub­parallel median margins; with about 15 short megasetae on dorsal margin; basal plate, in lateral view (Fig. 24), narrow, slightly curving ventrally toward anterior apex; in ventral view (Fig. 26) triangular, apex rounded. Phallus, in lateral view (Fig. 27), with anterior half nearly straight, gently curving ventrad at midlength, dorsal margin nearly straight; ventral margin curving; anterior 1/5 about 2x broader than its central part (Fig. 27); in ventral view (Fig. 28); phallobase forms minute lateral triangles; endotheca produced into long dorsal lobe; sperm channel divided into thick posterior and slender anterior parts; sclerotized posteroventral part narrow.
Holotype male: VENEZUELA: Dist. Fed. [Districto Federal]: Río Camuri Grande, 1 km S Camuri, (nucleo U.S. B.), 10.616°N, 66.715°W, 30 m, 24.i.1994, Holzenthal, Cressa & Rincón (UMSP 000022236) (UMSP, pinned).
Paratypes: same data as holotype — 3 males, 2 females (UMSP, pinned), 1 male, 1 female (NRM, pinned), 1 male, 1 female (NMNH, pinned), 1 male (IZAM, pinned).
Distribution. Venezuela (Districto Federal).
Etymology. The name camuriensis is derived from the type locality, Río Camuri Grande. The name is to be treated as a noun in the genitive case.
