The wingspan is about 15 mm. The forewings are ferruginous brown with a slightly paler oblique mark from the costa at two-fifths, followed by some rather darker suffusion. There is a fine white very oblique strigula on the costa at three-fourths. The discal stigmata are dark ferruginous fuscous, the first minute and the second rather small. There is also a darker terminal line. The hindwings are dark fuscous.[2]
