(Figs 33)

Material studied: ♂ Holotype: S. CELEBES, Tator, Rante Pao , 15.VII. 1982, G. de Rougemont / HOLOTYPE Oedichirus torajah des. 2015 G. de Rougemont [ CRO ].

Description: length: 7.6 mm; length of fore-body: 3.3; length of head: 0.85; breadth of head: 1.02; length of antenna: 2; length of pronotum: 1.25; breadth of pronotum: 1.1; length of elytron: 1.05; breadth of elytra: 1.25. Body deep black, all appendages testaceous, apices of femora lightly infuscate. Dorsal surfaces glossy, devoid of microsculpture. Pubescence erect, moderately short on fore-body, longer and denser on abdomen. Habitus: Fig. 33h.

Head strongly transverse; eyes large; post-ocular border consisting of an entire, not very salient carina which forms a distinct but very small tooth some distance behind eye, and a series of punctures in an interrupted groove above the carina; puncturation of disc consisting of half a dozen irregularly disposed punctures of different sizes at the level of the anterior half of eyes, four very small ocular punctures, and a transverse series of four large contiguous punctures before base. Pronotum elongate, the sides retracted in almost straight lines to posterior margin, without an evident lateral border; puncturation of disc consisting of a pair of discal series of five punctures each, six other punctures arranged in a rough circle in from of this, and a few scattered lateral punctures. Micropterous, humeral angles completely obsolete, the sides of elytra from base to postero-lateral angles, widest a little behind middle; puncturation coarse, sparse, irregular. Abdominal punctures arranged in discrete transverse rows; keels and grooves on anterior margins of tergites long.

Male abdominal sternite VII unmodified; sternite VIII: Fig. 33s8; aedoeagus: Fig. 33arl.

This and the widespread O. longipennis KRAATZ are the only species of Oedichirus so far known from Celebes, a sub-region notable for its high rate of endemicity. Staphylinidae in CRO labelled ‘Rante Pao’ were collected in various localities in the hills in a radius of 40 km around Rante Pao in the course of thirteen short visits to Torajaland (Tanah Torajah, abbreviated ‘Tator’) between 1975 and 1983.
