Fig. 55–61, 86.
Together with H. neblinensis, H. lara has a rounded, triangular gonocoxite which is unique among American Helicopsyche. Helicopsyche lara can be separated from H. neblinensis, in dorsal view, by a slightly wider tergum X having about 16 pairs of dorsal setae, and in lateral view, by the slightly more slender gonocoxite.
Male. Head: Antennal scape as long as eye diameter, with pale yellowish setae. Maxillary palp segments equally long, with dark brown and grey setae. Cephalic warts oval, about half as long as eye diameter; with yellowish setae, some dark brown near lateral margins. Forewing golden brown, length 5.1–5.4 mm. Sternum VI process (Fig. 55, 56) 1/ 3 its segment length, covered by microtrichiae; in lateral view (Fig. 55), nearly straight, slender along its length; in ventral view (Fig. 49), with proximal half slightly tapering, in distal half parallel­sided; apex bearing numerous ventral lamellae (Fig. 56).
Male genitalia (Fig. 57–61). Segment IX, in lateral view (Fig. 57), with anterior lobe triangular, oriented anteriad and located at midlaterally on segment; anterodorsal and anteroventral margins slightly concave; in dorsal view (Fig. 58), with inner margin widely ellipsoid; in ventral view (Fig. 59), with minute posterior process; lateral apodeme present as anteriorly oriented, nearly straight line (Fig. 57) reaching anterior margin; sub­marginal line absent; tergal transverse apodeme narrow; sternal transverse apodeme well developed. Segment X, in lateral view (Fig. 57), oriented posteroventrad, nearly straight; proximal half with dorsal and ventral margins parallel, distal half tapering toward rounded apex; in dorsal view (Fig. 58), slightly narrowing distally; apex without notch (Fig. 58); with about 16 pairs of about equally long megasetae in longitudinal group starting at midway on segment. Superior appendage (Fig. 57) club­shaped in lateral and dorsal views (Fig. 57, 58); curving posteriorly in dorsal view (Fig. 58). Primary branch of gonocoxite, in lateral view (Fig. 57), generally triangular, with undulate dorsal margin; apex rounded in lateral and dorsal views (Fig. 57, 58); central part of primary branch about as wide as height of central part of tergum X (Fig. 57); anterodorsal margin nearly straight, smooth; posteroventral margin nearly straight, undulated; basimesal lobe large, rectangular and protruding primary branch in lateral view (Fig. 57); in ventral view, cone­shaped (Fig. 59); with slightly undulating and diverging median margins armed with a strong seta; with about 8 short megasetae on apical margin; basal plate, in lateral view (Fig. 57), nearly straight, apex pointed; in ventral view (Fig. 59), strongly pointing anteriorly. Phallus, in lateral view (Fig. 60), gently bent ventrad at midlenth, dorsal margin nearly straight along its length; ventral margin gently concave; anterior 1/5 nearly 1.5x broader than its central part (Fig. 60); in ventral view (Fig. 61), tapering toward midlength; phallobase apparently absent; endotheca strongly produced (Fig. 60); sperm channel undivided; sclerotized posteroventral part narrow (Fig. 60), forming a truncate plate in ventral view (Fig. 61).
