Description.— Head: Scales of vertex and frontoclypeus brown tipped with pale brown; outer surface of labial palpus pale brown intermixed with few brown scales, inner surface pale brown; scape pale brown intermixed with few brown scales, flagellum pale brown; male 4 th flagellomere not protuberant, 5 th and 6 th flagellomeres slightly excavated; proboscis pale brown. Thorax: Tegula and mesonotum pale brown. Legs pale brown [many scales missing]. Forewing (Fig. 327 ): Length 7.6 mm (n = 1 ), pale yellow intermixed with pale brown and few brown scales. Undersurface pale brown. Hindwing: Pale brown. Abdomen (Fig. 120 ): Male with 4 transverse, irregular rows of sex scales on intersegmental areas between terga 2–3 and terga 3–4 . Sex scales between terga 2–3 appear equal in size as sex scales between terga 3–4 . Male Genitalia (Figs. 121–122 ): Uncus elongate, wide at base, broadly constricted above base, broadly rounded apically, apex acuminate and setose; gnathos setose, protuberant, wide throughout length, upturned apically; tegumen slightly widened basally; dorsal strut of tegumen with arms convergent, fusing from posteroventral margin, and gradually widening to base of uncus; valva with costa straight from a shallow depression slightly beyond a slanted, basal, digitate process to apical furca; furca falcate, with a wide base; sacculus twisted apically, constricting valva near midlength, widening distoventrally, forming an elongate and broadly rounded cucullus; cucullus membranous and setose; vesica of aedeagus denticulate, bearing a small conical, apical cornutus, with a large dilated and hollow, basal cavity.
