description: Helicopsyche (Feropsyche) auroa, new species
Fig. 29–35, 89
The new species is separated from all other American Helicopsyche species by the presence of a short sternum VI process together with a widely triangular gonocoxite with its prominent, sharply tapering basimesal lobe.
Male. Head: Antennal scape as long as eye diameter and distal maxillay palp segment. Maxillary palp with proximal segment about 2/3 length of distal segment. Cephalic warts rounded, slightly convex, about 1/2 as long as eye diameter, with pale yellow and brown setae. Forewing golden brown, length 4.5–4.6 mm. Sternum VI process (Fig. 29, 30) about 1/3 its segment length, covered by microtrichiae; in lateral view (Fig. 29), nearly straight and slightly tapering before wider apex, oriented posteroventrally; parallel­sided in ventral view (Fig. 30); apex bearing ventral lamellae (Fig. 30).
Male genitalia (Fig. 31–35). Segment IX, in lateral view (Fig. 31), with anterior lobe hyperboloid, oriented anteriad, present midlaterally; anterodorsal margin straight; anteroventral margin concave ventrally; in dorsal view (Fig. 32), with inner margin widely hyperboloid; in ventral view (Fig. 33), with minute posterior process; lateral apodeme present as anteriorly oriented, nearly straight line (Fig. 31) reaching anterior margin; submarginal line absent; tergal transverse apodeme absent; sternal transverse apodeme absent. Segment X, in lateral view (Fig. 31), oriented posteroventrad, nearly straight but with dorsal lobe at proximal part; slightly tapering along its length, apex slightly pointed; in dorsal view, (Fig. 32), slightly narrowing toward wide, rounded apex, lacking notch; with about 12 pairs of about equally long megasetae in longitudinal group starting at dorsal lobe, and about 5 pairs of smaller megasetae at lateral margin. Superior appendage (Fig. 31) tubular in dorsal view, slightly club­shaped in lateral view, oriented posterolaterally. Primary branch of gonocoxite, in lateral view (Fig. 31), generally widely triangular, with slightly undulate dorsal margin; apex rounded in lateral view, produced into finger­like process visible in dorsal view (Fig. 32); central part of primary branch slightly wider than height of central part of tergum X (Fig. 31); anterodorsal margin nearly straight, smooth; posteroventral margin weakly concave; basimesal lobe large, cone­shaped, strongly protruding primary branch, apically narrowing in lateral and ventral views (Fig. 31, 33), with slightly undulating, diverging, median margins; with about 9 short megasetae on dorsal margin; basal plate, in lateral view (Fig. 31), narrow, slightly sigmoid; in ventral view (Fig. 33), narrowly triangular, apex truncate. Phallus, in lateral view (Fig. 34), anterior half nearly straight, gently bent ventrad at midlength, dorsal margin concave; ventral margin angled; anterior 1/5 about 1.5x broader than its central part (Fig. 34); in ventral view (Fig. 35), phallobase forms narrow, ventral band; endotheca produced into long dorsal lobe; sperm channel divided into long, thick posterior and slender anterior parts; sclerotized posteroventral part narrow.
