A medium sized crambid (23-26 mm wingspan). Forewings chocolate brown (dark fuscous), lacking a longitudinal median silver white stripe and a white stripe in the costal margin, but having terminal dark brown dots. The hind wings are also chocolate brown. Also known as Acigona comptulatalis. Somewhat similar to Catoptria maculalis but the latter has two light blotches in the forewings as well as shorter wings. Also similar to Neodactria luteolella and N. caliginosella but the forewing apex in them is more sharply angled and is even slightly produced.
