The wingspan is about 16 mm. The forewings are light ochreous brown, somewhat darker posteriorly. There is a white costal streak from near the base to four-fifths, interrupted by an inwardly oblique bar of ground colour about the middle. There is a white spot on the inner margin at one-third, preceded by a dark fuscous suffusion, and two small cloudy white spots on the inner margin at two-thirds. There is a moderate white median longitudinal streak from the base to four-fifths, sinuate upwards in the middle, and with the extremity bent upwards, partially margined with dark fuscous suffusion, which is continued posteriorly as a broad band to the hindmargin. There is a moderate irregular-edged white submarginal streak from the apex to the anal angle. The hindwings are ochreous whitish.[2]
