The butterfly, which has a wingspan of 45 to 55 mm, is dark brown above. It resembles the common banded awl (Hasora chromus), except in the case of having a broad white band on the under hindwing which is outwardly diffused; also, its wings are more prominently glossed.[6][7]
Other differentiating characteristics are:
Male: The upper forewing has an apical spot, sometimes with another in 3. The upper forewing has no brand.[6]
Female: The apical spot in the case of the female is larger, and there is an additional spot in 2.[6]
