D e s c r i p t i o n: Length: 10.5 mm; length of fore-body: 4.4; length of head: 1.12; breadth of head: 1.42; length of antenna: 3.1; length of pronotum: 1.65; breadth of pronotum: 1.2; length of elytron: 1.2; breadth of elytra: 1.37. Body black, all appendages pale testaceous. Head and pronotum glossy, devoid of microsculpture; elytra shiny, with very faint microsculpture; abdominal tergites entirely microsculptate except on posterior margins of first four segments. Pubescence long, pale, semi-erect or decumbent, fairly dense on abdomen. Habitus: Fig. 4h.

Head moderately transverse; eyes large and protruberent; carina of post-ocular border not evident, but associated groove broad and deep, punctate; disc coarsely and irregularly punctate, the interstices mostly wider than diameter of punctures. Pronotum strongly elongate, behind anterior angles scarcely wider than head, the sides retracted to narrow base; lateral margins entirely bordered; puncturation of disc forming a pair of discal series of seven punctures each, the space between them smooth, a little raised and impunctate in posterior half, 6-7 scattered lateral punctures, and smaller punctures near anterior and along lateral margins. Micropterous, humeral angles completely obsolete; surface depressed, slightly concave in lateral view; puncturation finer than that of pronotal disc, irregular. Keels and depressions of anterior margins of abdominal tergites short and not very prominent; punctures of tergites disposed randomly, the punctures on anterior segments almost as coarse as those of elytra, sparser and finer on posterior segments.

Male: abdominal sternite VII unmodified; sternite VIII: Fig. 4s8, with a moderately large apico-median emargination; aedoeagus not seen (dissected by LAST, but detached from mounting card and lost).

Female: abdominal sternite IX: Fig. 4vp.

This species is similar in colour, puncturation and general appearance to O. endomanensis nov.sp. and to two other undescribed species from Irian Jaya in the SMNS, but is larger than any of those.
