Oedichirus hochimini nov.sp.

(Figs 44)

Material studied: ♂ Holotype: VIET NAM N (Ha Nang), 160 km NNW Hanoi, 150-200 meINE env. of Na Hang [sic], 1/ 14.VI.96, J. Roma & A. Napalov / J.F. Cornell Colln. 2008 Acc. Z-20, 351 FIELD MUSEUM / OEDICHIRUS det. P.N. Thomas 2012 / HOLOTYPE Oedichirus hochimini Des. G. de Rougemont 2017 [ FMC].

Description: Length: ca. 8.6 mm; length of fore-body: 4; length of head: 0.85; breadth of head: 1.1; length of antenna: 2.6; length of pronotum: 1.27; breadth of pronotum: 0.97; length of elytron: 1.75; breadth of elytra: 1.4. Body entirely black; mouthparts, antennae and legs entirely pale testaceous. Fore-body devoid of microsculpture, abdomen entirely microsculptate. Pubescence of elytra and abdomen pale, long, semierect. Habitus: Fig. 44h.

Head moderately transverse; post-ocular border strong and salient, forming a large postocular tooth; puncturation of entire disc coarse, dense and fairly homogenous, the punctures lying in individual foveate depressions. Antennae long. Pronotum long, the sides retracted in almost straight lines from widest point to base; lateral margins not bordered; puncturation dense, comparable to that of head, but with a vestige of discal series in the form of two longitudinal arcuate depressions containing about six punctures enclosing other punctures. Fully winged; elytra remarkably long, with prominent humeral angles, sides slightly rounded, widest at posterior 2/3 rds; puncturation homogeneous, denser and a little finer than that of pronotum. Abdominal puncturation disposed randomly, coarse and dense on tergites III-VI, sparser and shallower on VII-VIII.

Male: abdominal sternite VII: Fig. 44s7; sternite VIII: Fig. 44s8, the surface of sternite anteriad to emargination impunctate, strongly micro-reticulate; aedoeagus: Fig. 44arl, the right paramere slender and short.

O. hochimini nov.sp. has the general appearance of O. pendleburyi CAMERON , but is immediately distinguished by its much longer elytra. It shares the unusual character state of an entirely microsculptate abdomen with O. strictipennis nov.sp. from Thailand, but the facies of the two species are quite different, particularly by virtue of the shapes of the elytra.
