The wingspan is about 30 mm. The forewings are dull grey brown with a fine darker antemedial line from the subcostal and a medial darker spot in the cell, followed by an ochreous spot. There is a double incurved fuscous line on the discocellular divided by a fine ochreous line. The postmedial line is faint, preceded by small pale ochreous spots. The hindwings have a fuscous shade on the discocellular, followed by a pale ochreous spot which is outwardly edged by a faintly darker postmedial line.[2]
