Diagnosis. This species is different from other congeners in the following external characters: smaller than other congeners (length of forewing: 18–21 mm in male); the wing colour is pale yellowish brown, diffused with bluish black spots; area outside the postmedial line usually forms a bluish black dark band, which is interrupted between M3 and CuA1 of the forewing; the discal spots on both wings are strip-like, not stellate; the underside of the wings is greyish black, the transverse lines are similar to those on upperside, and the terminal band is absent; Sc is free, R1 and R2 are long stalked; the eighth sternite of the male abdomen does not have a cleft. There are also differences in the male genitalia: the uncus lacks lateral processes, as in O. exemptaria ( Thailand, Borneo, Sumatra, Singapore, Peninsular Malaysia), O. basiscripta (Borneo, Peninsular Malaysia), and O. satoi (Borneo) ; the gnathos median process is shorter and rounded terminally; the costa is not angled dorsally and medially; the dorsal margin of the sacculus is a straight spinulose sclerotized band, which is of even width from the base to the end and covering on the same spinulose band-like ampulla; the juxta is long and narrow, its anterior margin not concaved medially. The aedeagus lacks sclerotized spines; the vesica has two large cornuti.

Distribution. China (Guangdong, Yunnan, Tibet), Thailand.

Remarks. This species is quite different from the other congeners in both the external and male genital characters. Further study to estbalish a clear systematic position of the species is needed.
