Description: length: ca. 10.5; length of fore-body: 4.2; length of head: 1.85; breadth of head: 1.5; length of antennae: 3.1; length of pronotum: 1.58; breadth of pronotum: 1.2; length of elytron: 1.28; breadth of elytra: 1.43. Body black, palpi, antennae and legs testaceous. Head and pronotum shiny but clearly, densely micro-reticulate, abdominal tergites entirely covered with strong transverse micro-striae. Pubescence sparse, short and erect on fore-body, denser, long and decumbent on abdomen. Habitus: similar to Fig. 4h.
Male: abdominal sternite VIII: Fig. 5s8; aedoeagus: Fig. 5arl; Plate AEB.
Female: abdominal sternite IX: Fig. 5vp.
In colour, habitus and puncturation this species is indistinguishable from O. novacaledonicus, but differs in its averagely lesser size, stronger microsculpture both of the head and pronotum and of the abdomen, as well as in the primary sexual characters.
