Diagnosis. O. floccosa is distinctive by the long and dense reddish brown scales on the hind leg, and the basal half of the hind wing in the males. O. floccosa has a simple valva as in O. hypocrites and related species mentioned under that species, but the valva is much shorter, the costal length is also relatively short (less than the saccus length). But in O. hypocrites and other close related species the costa is longer than the saccus. The male genitalia resemble those of O. glabrosa Holloway, 1996 (Borneo; BMNH Slide No. 16747) and O. simplex ( Warren, 1912) (Sulawesi, Seram, Irian Jaya); but O. glabrosa and O. simplex lack any sclerites related to the juxta, which are present but small and blunt in O. floccosa . The eighth sternite is quite different from other congeners. It is deeply concave mesally in O. floccosa , but only shallowly excavated in O. glabrosa . The female genitalia are distinctive in having two finger-like lateral lobes at the juncture of the ductus bursae and the corpus bursae.

Distribution. China (Hainan), Philippines, Malaysia, Indonesia.
