Type material

Holotype. CHINA: Yunnan Prov.: male, Jinghong City, Nabanhe Nature Reserve, Guomenshan, alt. 1,200 m, 8-V-2009, Jia-Yao HU & Zi-Wei YIN leg.

Description

Body length: 6.8 mm; forebody length: 3.4 mm.
Body (Fig. 9) shiny, head, pronotum and elytra dark metallic blue, abdomen black and iridescent; maxillary and labial palpi brown with basal segments slightly paler; antennae brown, first segments and apical halves of following two segments black; legs black with femora and front coxae yellowish.
Head slightly wider than long (ratio 1.12); eyes large and convex, tempora distinctly shorter than eyes seen from above (ratio 0.18); dorsal surface of head with coarse and dense punctation; clypeus and vertex lacking punctures; surface with fine and dense microsculpture of transverse waves, becoming almost meshed anterior to vertex. Antennae slightly widened toward apex, segments II and III subequal in length, IV and V slightly longer than wide, segments VI–X about as long as wide, last segments about as long as two preceding segments combined.
Pronotum about as long as wide; dorsal rows irregular, each with 16 coarse punctures, each row expanding into group of punctures posteriorly; sublateral rows each expanded into irregular group of nine to ten coarse punctures; some distinctly finer punctures scattered among coarse punctation; with many dense and fine punctures bearing whitish hairs in wide strip along lateral margin; surface with fine and dense microsculpture of transverse waves. Scutellum with 14 punctures, with fine microsculpture of transverse waves. Elytra at base about as wide as pronotum at widest point, at suture slightly shorter (ratio 0.74), at sides slightly longer (ratio 1.26) than pronotal midline; punctation coarse and dense, on disc forming transverse rugae; pubescence dark, intermixed with whitish hairs, particularly on lateral portion of each elytron; surface without microsculpture. Wings fully developed.
Abdomen with tergite VII bearing distinct whitish apical seam of palisade fringe; punctation moderately fine and dense; tergite III with distinct tuft of golden-reddish tomentose pubescence on each lateral portion; pubescence black at middle portion, with some whitish hairs at both lateral portions and at apical margin of each tergite; surface with fine and dense microsculpture of transverse waves.
Male. First four segments of front tarsus distinctly dilated. Sternite VIII (Fig. 10) with two long setae on each side, with wide, shallow, arcuate medioapical emargination. Sternite IX (Fig. 11) simply rounded in medioapical emargination, without differentiated setae. Tergite X (Fig. 12) with five long setae near posterior margin and several shorter setae anterior to them; Aedeagus (Figs 13–15) with median lobe gradually narrowed into cone-shaped apex; paramere extending slightly beyond apex of median lobe; with two setae at apex, two slightly shorter setae and one distinctly longer seta at each lateral margin below apex; underside of paramere with sensory peg setae forming two regular longitudinal rows, each with nine or ten peg setae.
Female. Unknown.

Distribution

Known only from the type locality (Southwest China: Yunnan Province).

Remarks

Quedius maoxingi is closest to Quedius barbarossa Smetana, 2002 due to similar form and color of the body. The new species can be distinguished from Quedius barbarossa by the pronotum with some finer punctures scattered among coarse punctation, the scutellum with several punctures and by the aedeagus with symmetrical paramere (Fig. 15). Quedius barbarossa lacks fine punctures scattered among coarse punctation, its scutellum lacks punctures and the aedeagus bears distinctly asymmetrical paramere.

Etymology

The species is named in honor of Maoxing Tian (Administration of Nabanhe River Watershed National Nature Reserve) who helped a lot during our collection in Yunnan. Key to the multipunctatus species group of Quedius (Raphirus) from Yunnan Province, China
