FIGURES 22–28. Helicopsyche camuriensis , new species , holotype. 22—sternum VI process, lateral; 22—sternum VI process, ventral; 24—male genitalia, lateral; 25—male genitalia, dorsal; 26—male genitalia, ventral; 27—phallus, lateral; 28—phallus, ventral. 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.

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.
