Fig. 52–59, 61
Helicopsyche sanblasensis, new species is unique in having a combination of a very short segment IX, a nearly 3­branched primary branch of the gonocoxite, and a very long, coneshaped basimesal lobe. With respect to the genitalia, especially the shape of the gonocoxite, H. sanblasensis is similar to H. extensa Ross and H. dampfi.
Male head. Cephalic warts oval and flat. Postantennal setal warts not observed. Antennal scape about as long as each maxillary palp segment and eye diameter.
Male wings. Forewing (Fig. 52). Forewing brownish, length about 3.2 mm; hind wing length 2.3 mm. Hind wing venation and hamuli not observed.
Male abdomen and genitalia (53–59). Segment IV with broken process (Fig. 53–54). Segment IX (Fig. 55) with anterior lobe triangular in lateral view, oriented anteriad and located dorsally on segment; anterodorsal margin nearly straight, about as long as shallowly concave anteroventral margin; in dorsal view with inner margin widely ellipsoid (Fig. 56); in ventral view with wide central posterior process (Fig. 57). Lateral apodeme curving slightly anterodorsad in lateral view (Fig. 55), tapering and fading before anterior margin; sub­marginal line absent; tergal transverse apodeme absent; sternal transverse apodemes short. Tergum X oriented posteroventrally in lateral view (Fig. 55), nearly straight and cone­shaped, with apex pointed; widening at midlength and narrowing toward rounded apex in dorsal view (Fig. 56), apical notch shallow, with about 7 pairs long dorsal and 5 pairs short lateral megasetae. Superior appendage thick, slightly club­shaped in dorsal view (Fig. 55). Primary branch of gonocoxite with deeply concave posterodorsal margin in lateral view (Fig. 55) resulting in 3­branched gonocoxite (basimesal lobe included); narrowest distally to base, with weakly undulate margins; anterodorsal margin smooth, apex cone­shaped in lateral view and strongly curving mesally in dorsal and ventral view (Fig. 56, 57); narrowest part of primary branch as wide as height of tergum X and narrower than tergum X width (Fig. 55, 56); anterodorsal margin nearly concave, posteroventral margin shallowly concave along its length, with 2 prominently erect setal bases (Fig. 55). Basimesal lobe broadly cone­shaped and apically pointed in lateral and ventral view (Fig. 55, 57), with median margins basally divergent and distally parallel (Fig. 57), about 6 megasetae on dorsal face. Basal plate narrow, slightly undulate in lateral view (Fig. 55); strongly pointed anteriorly in ventral view (Fig. 57). Phallus with ventral margin curved at middle in lateral view (Fig. 58); in lateral and ventral view (Fig. 58, 59) basal part slightly thicker than central region. Phallic basis narrow (Fig. 59). Endotheca produced, posteroventral part strongly sclerotized. Sperm channel divided inside phallus into slender anterior part and thicker posterior part (Fig. 58, 59).
Male holotype: PANAMA: San Blas: 2 km S. Nusagandi, 3.iii.1985 [Flint & Louton] (NMNH, pinned, genitalia in glycerol).
Distribution: Panama (San Blas) (Fig. 61).
Etymology: sanblasensis, derived from the type locality of the species, San Blas in Panama.
Remarks: Helicopsyche sanblasensis can be separated from H. extensa by the shorter, cone­shaped apical branch of the primary gonocoxite branch, the cone­shaped tergum X in lateral view, and the long and cone­shaped basimesal lobes. It is distinguished from H. dampfi by the shorter segment IX, the cone­shaped apical branch of the primary branch of the gonocoxite, and the longer and cone­shaped basimesal lobe.
