Adults. Face tufted. Labial palps sub-ascending (second segment loosely scaled, the terminal filiform). Wing-span 19–23 mm. Forewings conspicously cleft; 2-segmented; cleft from beyond the middle (from 2/3 to 3/4). The lower lobe expanded towards the apex. Forewings conspicuously patterned; greyish-ochreous striated black, or reddish-fuscous. Apical 2/3 of the terminal cilia white. The base of the fissure preceded not associated with noticeable marking. Forewing venation exhibiting the cell apically truncated. Forewing vein 8 present (stalked with 9, 11 remote); 9 present (stalked with 8). Forewing vein 10 present. Forewing vein 10 separate. Forewing venation summary: 11 remote. Hindwings conspicuously cleft; 3-segmented (the posterior lobe narrower than the other two); blackish or dark fuscous. Hindwings differently coloured from the forewings. Hindwings with a large black scale-tooth in the dorsal cilia of the posterior segment (and with a small black apical one as well). The large scale-tooth in the posterior hindwing segment located much beyond the middle of the dorsum. The second lobe 3-veined. Hindwing vein 3 present (in the middle lobe).
