Additional material: 1♀: VIETNAM, Ha Ga District, Lung Cu 1600 m, 5.V.2011, O. TOMINAGA / Oedichirus strictipennis nov.sp. det. 1016 G. de Rougemont [ CIK].

Description: length: 8 mm; length of fore-body: 3.5; length of head: 1; breadth of head: 1.05; length of antenna: 2; length of pronotum: 1.38; breadth of pronotum: 1.12; length of elytron: 1.1; breadth of elytra: 1. Body black, palpi, antennae and legs testaceous, the knees sharply infuscate. Fore-body devoid of microsculpture, abdomen entirely microsculptate. Pubescence of varying length, dark and pale, erect and semierect. Habitus: Fig. 42h.

Head scarcely transverse, temples as long as eye, forming marked posterior angles; post ocular border forming a strong dentiform angle well behind posterior margin of eye, and another slight prominence on posterior angle; puncturation coarse, very dense on entire surface of disc. Pronotum strongly elongate, the sides concavely retracted to distinct posterior angles before base; lateral margins bordered in anterior half; puncturation comparable to that of head, coarse and dense on entire surface. Elytra distinctly elongate, of characteristic shape, with obsolete humeral angles and surface strongly depressed in anterior half; puncturation comparable to that of head and pronotum, coarse and dense on entire surface; lateral margins with a conspicuous series of half a dozen large black setae in addition to the finer, paler setae of rest of surface. Keels and grooves of anterior margins of abdominal tergites long; puncturation disposed randomly, coarse and dense, comparable to albeit slightly sparser than that of fore-body.

Female: sternite IX: Fig. 42vp.

The shape of the elytra of this new species differs from that of all other species known from continental SE Asia; in this it is comparable to the South Indian O. niger CAMERON (Fig. 41) from which it differs by the finer and denser puncturation of the fore-body, and in the obsolete humeral angles (reduced but distinct in O. niger ). The entirely microsculptate abdomen is also distinctive.
