description
Description: Length: 9 mm; length of fore-body: 4.1; length of head: 1; breadth of head: 1.1; length of antenna: 3.3; length of pronotum: 1.35; breadth of pronotum: 0.95; length of elytron: 1.62; breadth of elytra: 1.45. Body reddish brown, sutural and posterior margins of elytra pale, yellowish-brown; mouthparts, antennae and legs pale testaceous. Body devoid of microsculpture except on anterior margins of abdominal tergites. Pubescence sparse, pale, long, erect. Habitus: Fig. 29 h. Head almost as long as broad, the temples long, narrowed in scarcely curved lines to neck, posterior angles obsolete; post-ocular border simple, consisting of a shallow groove, not forming a ridge or forming a salient angle; puncturation coarse, random, a little irregular, without discal series. Pronotum very long, broadest at one fifth of its length behind anterior margin, the sides thereafter concavely narrowed to base; lateral border represented by a seires of punctures in a groove extending from widest point to base; puncturation similar to that of head, without discal series. Elytra large, the puncturation similar to that of pronotum but denser and more regular. Punctures of abdomen disposed randomly, about as coarse as those of elytra, sparser on posterior half of tergites VI-VII, reduced to a few very small punctures of tergite VIII. Male: abdominal sternite VII unmodified; sternite VIII: Fig. 29 s 8; aedoeagus: Fig. 29 arl Female: sternite IX: Fig. 29 vp. This species most closely resembles O. tempestivus nov. sp. from which it can be distinguished, as from all other Bornean species, by the characters used in Key 2. The specimens collected by Wallace are from south-western Sarawak (former First Division), the only part of Borneo visited by Wallace on his three sojourns on the island. The holotype and associated paratype were found amongst undetermined Paederus spp. in the Hope / Westwood collection of Staphylinidae in the OUMNH; they have now been moved to a cabinet housing the museum’s collection of type specimens.
