A large, heavy-bodied, large-eyed moth with a bright green upperside and orange underside. Cannot be confused with any other species except Oryba achemenides, which is darker with a less contrasting pattern Antenna strongly clavate, black, with pale medial line ventrally.Eye very large.Abdomen with small lateral tufts and a pair of bright yellow lateral patches on segments 5 and 6.Abdominal spines broad, close together also on posterior tergites. Marginal band of forewing upperside strongly convex, as broad at M3 as the distance between this area and the distal margin of the dark olive-green median trapezoidal area, the edges of which are bordered with white scales. Tergite 7 with long hair-like scales that form an expansible fan. Forecoxal hair-brush vestigial. Forewing much more rounded than those of the male. Tergite 7 with long hair-like scales that form a simple tuft. Uncus longer than broad, densely hairy, the lobes about twice as long as broad medially in dorsal view.Gnathos a little longer than uncus.Juxta produced into a long, more-or-less clubbed process, denticulate on upperside, slightly incrassate distally.Valve very large, sole-shaped, with elongate-lanceolate, rather small stridulatory scales.Harpe not separated from the valve.Aedeagus divided into two slender processes, the incision extended proximad as a groove, each process ending in a short seta and two hairs, and bearing some short setae at the base.
