Forewing light fuscous with a bronze dorsal marginal stripe; a dorsal marginal stripe occupying near wing fold on basal to 2/3 of the forewing and a half of on apex with some white streaks and blackish spots; first white costa-stria beginning at 1/3 to base, stretched along costal margin near a half of forewing, smoothly downward and reached to bronze stripe obliquely; second white costa-stria narrower than first one; third one slightly bent inwards and apical part acute; an obscure tiny white spot on apex. Hind-wing ground colour is light greyish-ochrous.

Female genitalia (Fig. 2 J). Papillae anales as long as apophyses anteriores with long setae on apex; apophyses posteriores sclerotised, stout and triangular; apophyses anteriores slender and narrow. Ostium bursae wide at opening; antrum well sclerotised and elongated as long as apophyses anteriores or longer. Ductus bursae 2 times longer than antrum, sclerotised on base to just above corpus bursae and membranous near corpus bursae; ductus seminalis originating just below antrum, base sclerotised, curved and slightly turned back to ductus bursae. Corpus bursae are membranous, ovate and as long as ductus bursae without signum.
