Description: length (of type): 9.2 mm; length of fore-body: 4.2; length of head: 0.9; breadth of head: 1.12; length of antenna: 2.9; length of pronotum: 1.32; breadth of pronotum: 1.02; length of elytron: 1.7; breadth of elytra: 1.5. Body piceous, the posterior margin of elytra sometimes (type) rufescent, appendages testacous. Fore-body devoid of microsculpture; abdominal tergites III-VI with faint transverse micro-striation, tergites VII-VIII with very dense micro-punctures. Pubescence moderately long, semi-erect. Habitus: Fig. 31h.

Head moderately transverse, eyes large and prominent; post-ocular carina and groove well marked, forming a salient dentiform angle well removed from posterior margin of eye; frons with a few scattered very small punctures; punctures of disc larger, umbilicate, but much finer than those of pronotum, sparser on vertex, denser near eyes and base.

Pronotum strongly elongate, the sides slightly concavely retracted to posterior angles; lateral margin entirely but indistinctly bordered; puncturation visibly serially aligned, including two pairs of discal series of four and five punctures and a lateral seriesof 5-6 punctures and an anterior cluster of at least 15 smaller punctures as wel as small punctures along lateral margins, but all more or less confused in many specimens. Macropterous, elytra very long, ample, widest a little hehind middle, humeral angles well marked, and sides rounded between these and posterior angles; puncturation about as coarse as those of pronotum but very dense, the interstices everywhere much narrower than diameter of punctures. Punctures of abdominal tergites disposed randomly, dense, as coarse as those of elytra.

Male: surface of sternite VIIwith a pair of dentiform elevations, the right one larger than the left and projecting slightly beyond the posterior margin of sternite; sternite VIII: Fig. 31s8, with a large simple emargination; aedoeagus: Fig. 31arl, av.

Female: sternite IX: Fig. 31vp

Variability: some apparently fully mature specimens are brown rather than piceous. The species is indistinguishable in facies and puncturation from O. lannaensis nov.sp. from Thailand and Laos.

Distribution: Borneo, Java, Sumatra, Malay peninsula, Singapore.
