Diagnosis. On wing pattern, O. hypocrites shares the white spot on the forewing inner margin with O. retaka Holloway, 1996 (Borneo), O. vivida (Prout, 1922) (Moluccas) and O. leucospilota (Moore, 1887) (Sri Lanka). The fringes are reddish brown, with white spots on the vein ends. Apomorphies of the male genitalia of these four species are, a densely hairy and spinose subcostal area on a simple valva, and a pair of spinose processes posterior to the juxta. However the valva of O. retaka is much broader than in the other three species. Additionally the processes associated with the juxta are of even width in O. hypocrites, slightly curved in O. leucospilota, expanded posteriorly in O. vivida and very broad in O. retaka. There are also differences in the male eighth abdominal segment: the tergite is Y-shaped in O. retaka; widely Y-shaped in O. vivida; a relatively wider cleft in O. hypocrites, which is more strongly excavated in O. leucospilota; the sternite protrudes with a blunt mesal process in the distal margin in O. hypocrites; in O. vivida and O. leucospilota the sternite has two mesal processes; in O. retaka the sternite bears a cleft. The female genitalia have an oval lamella postvaginalis and wrinkled lamella antevaginalis. The ductus bursae is very broad and sclerotized, bearing a rounded lateral lobe. The corpus bursae is of similar length to the ductus bursae. The signum is bicornute.
Distribution. China (Hainan, Hong Kong, Yunnan), India, Vietnam, Thailand, Malaysia, Singapore, Indonesia.
