Description: length: 6-7 mm; length of fore-body: 2.8; length of head: 0.7; breadth of head: 0.9; length of antenna: 1.55; length of pronotum: 1; breadth of pronotum: 0.95; length of elytron: 0.84; breadth of elytra: 1.1. Body piceous to brown; palpi, antennae and legs testaceous. Dorsal surfaces devoid of microsculpture except on anterior margins of abdominal tergites. Pubescence very dense, short, erect, somewhat longer on elytra and abdomen. Habitus: Fig. 26h

Head strongly transverse; eyes about as long as temples, very protruberant; post-ocular border feeble, situated on lateral margin; puncturation coarse and very dense on vertex, the interstices much narrower than diameter of punctures, the latter umbilicate. Pronotum rather short and broad; lateral line entirely but inconspicuously bordered; puncturation coarse and very dense, the punctures as large as those of head, homogeneous but showing a trace of a mid-longitudinal line in some specimens (type). Elytra short and broad, transverse, the sides rounded, widest a little before middle; puncturation coarse and dense, the punctures a little larger but shallower than those of pronotum. Keels and grooves of anterior margins of abdominal tergites confused on tergite III, distinct and prominent on IV-VI; puncturation of tergites very dense, the punctures progressively finer from anterior to posterior margins of each tergite.

Male: abdominal sternite VIII: Fig. 26s8; aedoagus: Fig. 26arl.

Female: sternite IX: Fig. 26vp.

Very similar in size, puncturation and dense erect pubescence to O. mimopilosus nov.sp., from which it differs most evidently by its longer pronotum, the smaller emargination of the male sternite VIII and the aedoeagus.
