Similar to Ophiusa discriminans, differs in head and thorax being yellowish grey. Abdomen lack black patch. Forewings yellowish grey without black specks. A maculate line runs beyond the postmedial line. A grey and dark patch beyond the sub-apical spots, and hardly a trace of the patch at anal angle. A dentate sub-marginal line with the area beyond it reddish. Hindwing orange with the black reduced to a submarginal medial patch.[3]

Larva pale brownish, with numerous waved longitudinal black lines, between which are black specks series. There are some red between each pair of legs, and a black patch between each pair of prolegs.
