(Figs. 15–19)  
 Type locality. People’s Republic of China, W Sichuan, pass SE Barkam, between Zhuokeji-Lianghekou, 4100 m. Type material. HOLOTYPE: J (ASC, to be deposited in Muséum d’Histoire Naturelle, Genève), ‘ CHINA-W Sichuan Barkam, pass SE Barkam, pass between Zhuokeji-Lianghekou 4100 m, alpine zone 10-30.VI.2004, leg. R. Fabbri’.   
 Description. Head black, pronotum, elytra and abdomen piceous-black; head, pronotum and elytra with metallic bronze lustre, abdomen iridescent; both maxillary and labial palpi, antennae and legs testaceous, middle and hind tibiae markedly blackened. Head rounded, wider than long (ratio 1.15); eyes very large and convex, tempora very short, considerably shorter than length of eyes seen from above (ratio 0.12); no additional setiferous punctures between anterior frontal punctures; posterior frontal puncture touching posteriomedian margin of eye, one puncture between it and posterior margin of head; temporal puncture small, touching posterior margin of eye; surface of head with fine, moderately dense microsculpture of transverse and oblique waves. Antenna moderately long, segments 2 and 3 subequal in length, segments 4-7 longer than wide, gradually becoming shorter, segments 8–10 about as long as wide, segment 11 as long as two preceding segments combined. Pronotum about as long as wide, widely rounded basally, slightly narrowed anteriad, evenly transversely convex; dorsal rows left with four, right one with three punctures; sublateral rows each with three punctures, with posterior puncture situated slightly after level of large lateral puncture; surface of pronotum with microsculpture of transverse waves similar to that on head. Scutellum with punctures, exact number impossible to establish among surface microsculpture. Elytra quite short, at suture markedly shorter (ratio 0.66), at sides shorter (ratio 0.76) than pronotum at midline; punctation moderately fine, dense; transverse interspaces between punctures about as large as diameters of punctures; pubescence black; surface between punctures with microscopic irregularities. Wings apparently each reduced to nonfunctional, narrow stump. Abdomen with tergite 7 (fifth visible) without whitish apical seam of palisade setae; tergite 2 (in front of first fully visible tergite) entirely punctate and pubescent; punctation of tergites markedly finer than that on elytra, dense, becoming sparser toward posterior margin of each tergite and in general toward apex of abdomen; pubescence black; surface between punctures with excessively fine microsculpture of striae.   
Male. First four segments of front tarsus dilated, subbilobed, each with tenent setae ventrally, segment two somewhat narrower than apex of tibia (ratio 0.92); segment 4 narrower than preceding segments. Sternite 8 with three long setae on each side, apical margin with moderately wide and deep, obtusely triangular medioapical emargination, small area before emargination flattened and smooth (Fig. 15). Genital segment with tergite 10 evenly narrowed toward widely arcuate apex, sparingly setose, as in Fig. 16; sternite 9 with narrow basal portion, apical portion narrowly arcuate apically, without differentiated apical or subapical setae, setose as in Fig. 17. Aedoeagus (Figs. 18, 19) rather robust, median lobe subparallel-sided in middle portion, anteriorly narrowed into moderately long apical portion with subacute apex, on face adjacent to paramere, when paramere removed, with short carina far below apex of median lobe. Paramere rather large, widely subfusiform, in ventral view entirely covering median lobe except for very apex, with narrowly arcuate apex by far not reaching apex of median lobe; four minute setae at apical margin, median setae somewhat longer than lateral ones, two similar setae at each lateral margin below apex; sensory peg setae on underside of paramere situated as in Fig. 19.  
Female. Unknown.  
Length 4.0 mm.  
 Etymology. The specific epithet is the Greek noun ορος, -εος (a mountain) in apposition, referring to the occurrence of this species high up in the mountains.   
 Bionomics. No details are known about the collecting circumstances, except that it was taken in the alpine zone at 4100 m.   
 Geographical distribution. Quedius oros sp. nov. is at present known only from the type locality in Qiongilai Shan in western Sichuan.   
 Recognition and comments. Quedius oros sp. nov. is well characterized, in addition to the characteristic shape of the aedoeagus, by the markedly blackened middle and hind tibiae, combined with testaceous tarsi, and the uniformly black pubescence of the elytra and abdominal tergites.
