Oedichirus tempestivus nov.sp.

(Figs 28)

Material studied: ♂ Holotype: E. MALAYSIA, Sarawak, Gn. Matang , 20 Km E Kuching , 850 m, 25.V.1994, submontane for. #10, Löbl & Burkhardt [ MHNG].

Description: length: ca. 8 mm; length of fore-body: 3.5; length of head: 0.9; breadth of head: 0.92; length of antenna: 3; length of pronotum: 1.12; breadth of pronotum: 0.75; length of elytron: 1.42; breadth of elytra: 1.32. Body uniformely reddishbrown, mouthparts, legs and antennae pale testaceous (specimen slightly teneral). Microsculpture limited to anterior margins of abdominal tergites. Pubescence long, erect or semi-erect, sparse on fore-body, dense on abdomen. Habitus: Fig. 28h.

Head scarcely transverse, eyes large and very prominent; temples long, retracted in straight lines to neck, without posterior angles; post-ocular carina not very conspicuous, entire, not forming a dentiform angle behind eye; punctures irregularly scattered, Pronotum strongly elongate, the sides concavely retracted to base; lateral margin entirely bordered in the form of a punctate groove; puncturation of disc irregular, not forming discal series, denser near centre, sparser laterally and leaving larger impunctate areas near anterior angles. Elytra large, ample, with marked humeral angles, the sides dilated postriad to 1/5 th the distance from posterior angles; surface a little convex; puncturation homogeneous, finer and denser than that of pronotum. Anterior margins of abdominal tergites without discernibls keels, but with elongate depressions; punctures of tergites disposed randomly, rather sparse, the interstices in parts wider than the diameter of punctures.

Male: abdominal sternite VII: 28s7; sternite VIII: Fig. 28s8; aedoeagus: Fig. 28arl (the median lobe is collapsed and deformed, but the characteristically shaped process of the ventral plate is visible).

This member of the ‘Wallacei group’ differs from O. wallacei nov.sp. in its slightly smaller size, uniformly paler colour, shorter, pronotum which is more uniformly punctured, without a raised mid-line, shorter elytra which are more markedly dilated posteriad, and broader emargination of the male sternite VIII. The aedoeagi of the two species differ markedly.
