Diagnosis.

This species is hard to distinguish by its external characters. It differs from other species by the sacculus with a single process in the middle, while the sacculus usually has two processes in other species. Furthermore, the sclerotized plate on the valva is twice or three times as broad as others.

Head blackish-brown; labial palpus upturned, mixed with fuscous and black scales, stronger in male; maxillary palpus pale yellow; antenna brown, scape extension black, mixed with fuscous scales in male. Thorax mixed with brown and fuscous scales. Forewing covered with brown, black and pink scales; base mixed with yellow and black scales; costal margin yellow; postmedial fascia orange with brown edges, outer area covered with pink and fuscous scales; cilia grey. Hindwing with same pattern as forewing.
