11mm. This is a larger species than cesena, a slightly paler
grey, with the more evenly curved, fine, blackish postmedials highlighted by an
irregular paler grey zone just distally. The hindwing white zone has a more
irregular posterior margin, and the postmedial is parallel to the margin over
the posterior two-thirds of the wings. In the female genitalia the ductus
terminates in an expanded, conical, scobinate ostium. An externally similar
female from Luzon (slide 381) has a much shallower ostium, a much smaller signum
and a distally broader ductus; and its hindwing postmedial converges with the
margin slightly towards the dorsum. The ostial feature is also backing in cesena,
and its signum is intermediate in size.
