The wingspan is 16–20 mm. The forewings are fuscous, overlaid and suffused reddish brown and from the basal third of the costa an all-defined olive-buff fascia extends to the fold then continues to the tornus. From the apex to vein 2, an ill-defined olive-buff transverse fascia is found. The hindwings are sepia.[2]
