Additional material: 1♀: THAILAND, 24.12.92, Nakhon Ratchasima Prov. Khao Yai N. P., 1020 m, Schwendigen [sic] / Oedichirus uncifer n.sp. det. 2015 G. de Rougemont [ MHNG].

Description: length: 6.5 mm; length of fore-body: 2.9; length of head: 0.97; breadth of head: 0.92; length of antenna: 2.3; length of pronotum: 1.15; breadth of pronotum: 0.95; length of elytron: 0.77; breadth of elytra: 0.95. Body piceous, palpi, antennae and legs testaceous, knees lightly and indistinctly infuscate. Dorsal surfaces devoid of microsculpture. Pubescence pale on fore-body, darker on abdomen, moderately long, erect. Habitus: Fig. 48h.

Head scarcely transverse; post-ocular carina salient, ending anteriad in a very marked dentiform angle well removed from eye; puncturation fairly dense, confused, with small punctures on frons and large punctures posteriad leaving only a small transverse impunctate are on vertex. Pronotum moderately elongate; lateral margins entirely bordered with a fine carina adjacent to a series of small punctures; discal series of 5-6 punctures enclosing a small impunctate surface, the anterior and lateral parts with numerous, confused large punctures. Micropterous, elytra short, depressed, humeral angles completely obsolete; puncturation coarse and dense. Puncturation of abdominal tergites arranged randomly, the punctures almost as large as those of elytra.

Male: sternite VII unmodified; sternite VIII (Fig. 48s8) with a simple symmetrical apical emargination, without combs or spines; aedoeagus (Fig. 48arl) with a small hooked anterior process of the ventral plate of the median lobe.

O. uncifer nov.sp. is most similar to O. mediosiamensis nov.sp. and O. birmanus FAUVEL from which it may be distinguished by the characters given in the Key. In addition the pronotum is shorter and less densely punctate, with shorter discal series than in O. birmanus , and with quite different male sexual characters.
