Oedichirus endomanensis nov.sp. (Figs 2)

♂ Holotype: IRIAN-JAYA Prov. Jayawijaya, Endoman , 13.9.1992, 1400 – 1550 m, leg. A. RIEDEL ♀ HOLOTYPE Oedichirus endomanensis des. 2017 G. de Rougemont [ SMNS] ; 1♀ paratype: [Ibid.] ♀ PARATYPE Oedichirus endomanensis des. 2017 G. de Roiugemont [ CRO] .

D e s c r i p t o n: length: 8.5 mm; length of fore-body: 3.7; length of head: 0.95; breadth of head: 0.12; length of antenna: 2.3; length of pronotum: 1.32; breadth of pronotum: 1.12; length of elytron: 0.75; breadth of elytra: 0.92. Body black, all appendages testaceous. Dorsal surfaces glossy, devoid of microsculpture except on keels of anterior margins of abdominal tergites and faintly on tergites VI-VIII. Pubescence (possibly mostly rubbed off) consisting of only a few sparse fine hairs on head and abdomen. Habitus: Fig. 2h.

Head strongly transverse; post ocular carina salient, extending anteriad almost to posterior margin of eye, not forming an angle; puncturation consisting of two dozen moderately coarse punctures on vertex, not counting some much smaller ocular punctures and those of post-ocular grooves, the interstices almost everywhere wider than diameter of punctures. Pronotum strongly elongate, behind anterior angles only about as broad as head, the sides strongly convergent posteriad; lateral margins entirely bordered by a carina and half a dozen small punctures above carina in anterior half; punctures of disc larger than those of head, forming a pair of discal series of seven punctures each, the space between them smooth, slightly raised, impunctate except for a four scattered punctures at centre, a few lateral punctures, and about a dozen small punctures on each side along anterior and lateral margins. Micropterous, humeral angles completely obsolete; surface depressed, a little concave in lateral view; punctures about as large as those of pronotum, but denser, the interstices mostly narrower than diameter of punctures. Keels and depressions of anterior margins of abdominal tergites short, not very prominent; punctures of tergites disposed randomly, sparser and on anterior segments almost as coarse as those of pronotum, finer on posterior segments.

Male: abdominal sternite VIII: Fig. 2s8; aedoeagus: Figs 2arl, av.

Female: sternite IX: Fig. 2vp.

This species is similar in appearance and puncturation to O. lucidus nov.sp. but is smaller.
