The wingspan is about 10 mm. The forewings are pale ochreous largely suffused light brown-reddish and with a line of dark grey scales almost on the costa towards the base.

A black streak is found along the basal half of the fold, and an irregular thicker streak in the disc from before the middle to five-sixths. There are also three or four strigulae of irregular black scales along the termen and at the apex, as well as a white marginal line around the posterio
