(Figs 7)

Material studied: ♂ Holotype: MALAYSIA-W Perak, 25 km NE of Ipoh, 1200 m., Banjaran Titi Wangsa mts., KORBU mt., 27.i-2.ii.1999, P. Patcholatko leg. / HOLOTYPE Oedichirus patcholatkoi Des. 2016 G. de Rougemont View in CoL [ CIK].

Description: length: ca. 7.3 mm; length of fore-body: 3.6; length of head: 0.8; breadth of head: 0.87; length of antenna: 3.2; length of pronotum: 1.25; breadth of pronotum: 1; length of elytron: 1.42; breadth of elytra: 1.4. Head black, pronotum red, anterior 3/5 th of elytra black, posterior 2/5 th red, abdominal segments III-V red, VI-IX black; antennomeres I-X brown, the apex of each segment pale, antennomere XI entirely pale; basal halves of meso- and metafemora testaceous, distal halves and entire tibiae infuscate. Dorsal surfaces devoid of microsculpture. Pubescence on abdomen pale, long, semi-erect. Habitus: Fig. 7h

Head strongly transverse; post-ocular carina well developed, forming a sharp angle behind eye; puncturation of disc sparse, consisting of some very small frontal and ocular punctures, a couple of punctures behind post-antennae tubercles, a cluster of half a dozen punctures on vertex, and an arcuate transverse row of laterally elongate punctures before base. Pronotum moderately elongate, the sides concave between anterior and posterior angles; lateral margins without evident borders; puncturation composed of a pair of arcuate discal series of five large punctures, a few scattered small punctures before this and on anterior margins, lateral series of two large punctures, and the usual small punctures on lateral margins. Elytra ample, very convex, widest 3/5 th from anterior margin, the sides rounded; puncturation of disc arranged in three longitudinal series of small punctures and other small punctures on lateral margins. Punctures of abdominal tergites arranged in three discrete transverse rows behind anterior rows of short keels.

Male: sternite VII unmodified; sternite VIII: Fig. 7s8, with a deep asymmetrically rounded emargination enclosing a membranous flange and comb of pale setae, bordered on the right by a tooth, edentate on the left; aedoeagus: Fig. 7arl, the ventral plate with a truncate process.

O. patcholatkoi nov.sp. is very similar to the only other member of the O. Alatus group with entirely black tibiae, Oedichirus sp A4 from northern Thailand, from which it differs by its slightly finer elytral puncturation.
