Diagnosis.

The median discoidal stigma, cubital and dorsal patches of the forewings form an oblique thin white streak. In female genitalia, the membranous pouch anterad from the antrum and the leaf-shaped sclerotisation of the corpus bursae allows to recognise this species. Male genitalia are not known.
