Description: length: 8.2 mm; length of fore-body: 4; length of head: 0.95; breadth of head: 1.02; length of antenna: length of antenna: 2.7; length of pronotum: 1.25; breadth of pronotum: 1; length of elytron: 1.65; breadth of elytra: 1.14. Body black, all appendages testaceous. Fore-body devoid of microsculpture except on anterior part of elytra; abdominal tergites entirely microsculptate, the sculpture very strong on anterior margins of tergites, consisting of transverse microstriation elsewhere. Pubescence pale, erect, fairly short on fore-body, longer on abdomen. Habitus: Fig. 45h.

Head strongly transverse; eyes large and protruberent; post-ocular border pronounced, grooved and carinate, the carina forming a prominent tooth a little distance from eye; disc strongly punctate but leaving the middle of frons and a transverse area on vertex impunctate, the interstices elsewhere mostly wider than diameter of punctures. Pronotum strongly elongate; lateral margins not bordered; puncturation comparable in density to that of head, but with a discernible pair of arcuate discal series of six punctures each enclosing a pair of other punctures at their anterior end. Fully winged, elytra long and ample, with marked humeral angles, broadest at posterior 2/3 rds. Puncturation of abdomen disposed randomly, comparable in coarseness and density to that of elytra.

Male: posterior margin of sternite VII: Fig. 45s7, with a small arcuate median emargination bordered on either side by a broad, blunt tooth and preceded by an impunctate, transversely micro-striate impression; sternite VIII: Fig. 45s8, with a large and deep ogival emargination preceded by a deep impression; surface of impression strongly microsculptate; aedoeagus: Figs 45 al, av.

Female: sternite: Fig. 45vp.

In its facies, colour and puncturation this new species is indistinguishable O. pendleburyi CAMERON; it differs by the shape of the aedoeagus and that of the male sternites VII and VIII, the emargination of the latter being deeper and with a more acute fundus. It also resembles O. laoticus nov.sp. but is a smaller species with quite different sexual characters.
