Adults of small body size; male forewing length 6-8 mm. Body coloration greyish-brownish. Forewings transparent to pale yellowish, crossveins sometimes dark and shaded. Costal cross veins of forewings not forked. Hindwing MA and anterior branch of MP forked distal to outer series of gradate cross veins. Male: Abdominal segment 7 enlarged.

Male sternite 9 long, strongly extending posteriad; gonocoxites 9 as huge plates with digitiform gonostyli 9 and processus-like gonapophyses; complex of gonocoxites + gonostyli + gonapophyses 10 amalgamated with sternite 9, forming a pseudoapex of the latter and framing it laterally; gonocoxites 11 fused into a bow-like bridge.
