Description: length: 10-10.5 mm; length of fore-body: 4.4; length of head: 1.2; breadth of head: 1.32; length of antenna: 3; length of pronotum: 1.7; breadth of pronotum: 1.4; length of elytron: 1.35; breadth of elytra: 1.58. Body black; palpi, antennae and legs testaceous, the kness not, or only very slightly and narrowly infuscate. Head and pronotum densely microsculptate, giving a sericeous appearance; elytra with less evident and sparser microsculpture; abdominal tergites with dense trasverse micro-striation. Pubescence short, very sparse and erect on fore-body, longer, denser and decumbent on abdomen. Habitus: similar to Fig. 4h.

Male: abdominal sternite VIII: Fig. 6s8; aedoeagus: Figs. 6arl, arlB (with inner sac everted), av; Plate AEC.

Female: abdominal sternite IX: Fig. 6vp

In habitus, colour and puncturation this species is indistinguishable from O. novacaledonicus except in that the head and pronotum are considerably more strongly microsculptate; the only other discernible differences are that the knees are more narrowly, or not infuscate, and the abdominal puncturation is marginally sparser.
