Outer surface of labial palpus brown intermixed with pale-brown scales along apical margin of segment 2, inner surface pale brown. Antennal scape pale brown, pecten brown, flagellum brownish gray. Proboscis pale brown.</p> <p>Thorax: Tegula with basal 2 / 3 brown, apical 1 / 3 pale brown; mesonotum with basal 1 / 3 brown, apical 2 / 3 pale brown. Legs brown intermixed with pale-brown scales near midsegments and along apical margins of all segments and tarsomeres. Forewing (Fig. 366): Length 3.8–4.9 mm (n = 7), pale brown intermixed with brown scales; basal 1 / 3 pale brown except costa brown; submedian fascia complete or incomplete; cell with three spots, one near middle, two on apical end along crossvein; marginal spots present. Undersurface brown. Venation (Fig. 31) with M 3 and CuA 1 arising from a common point on distoposterior part of cell; cubital veins divergent from bases; CuA 1 straight, CuA 2 broadly curved. Hindwing: Translucent pale brown. Venation (Fig. 31) with cubitus 4 -branched with M 2 arising from distoposterior part of cell and M 3 and CuA 1 branching near 1 / 2.</p> <p>Abdomen: Male genitalia (Figs. 159–160): Uncus narrowed from widened base, downcurved, narrowly rounded apically, setose, shorter than width of anal opening. Gnathos, narrow ring, confluent with tegumen, ventroposterior margin narrowly emarginate mesially. Sockets of tergal setae not extending beyond midlength of tegumen. Valva divided; ventral part basally protracted inwardly, gradually widened beyond base, slightly narrowing apically, forming inwardly curved spinelike process; process setose on outer surface, planate on inner surface; ventral margin sparsely setose, slightly upturned beyond middle, narrowing to near base of setose lobe at base of apical process; dorsal part with apical portion of costa extending dorsally, forming setose digitate process; process broadly curved inwardly; basal ridge of digitate process extending ventrally fusing with dorsal ridge of proximal flange; flange ellipsoid, microtrichiae throughout except, setose along ventral margin; margin mostly entire. Juxta bandlike. Vinculum semicircular. Phallus and sclerite of phallus about as long as valva; phallus straight, sclerite of phallus slightly curved at 1 / 4; anellus with widened base, constricted subapically, forming nipplelike apical end, and bearing two setal clusters on midregion.
