Phazaca monticesena Holloway sp. n.
Gathynia cesena Swinhoe, sensu Holloway, 1976: 88.
Diagnosis
♀ 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.
