The wingspan is 70 mm for males. It is similar to Isognathus rimosa rimosa and Isognathus rimosa papayae but has narrower wings. The forewing upperside is unicolorous brown, shaded with white, except for a yellow band along the posterior margin and the faint traces of a distal marginal band. The basal area of the hindwing underside is yellow, the rest is brown with a bluish tinge, becoming black towards the anal angle.
