Type material.
Holotype. male, CHINA: Tibet: Gedang, Motuo County, [29°27.49'N; 95°32.57'E], ca. 1600m, 11.v.2011, Huo LZ leg (SCAU). Paratypes. The same information as the holotype; 1 female, Tibet: Beibeng to Hanmi, Motuo County, [29°19.23'N; 95°07.21'E], 800-2100m, 5-8.v.2011, Huo LZ leg (SCAU); 1 female, Tibet: No. 1 Bridge, Hanmi, Motuo County, [29°21.06'N; 95°04.53'E], ca. 2000m, 14.v.2009, Wang XM leg (SCAU).
Diagnosis.
Renius cornutus can be easily distinguished from other species of the tribe Chilocorini by the roundish body with bluish black pronotum and elytra; medially projecting clypeus and subtriangular sclerite between coxites.
Description.
TL: 4.43-5.00 mm, TW: 4.56-5.00 mm, TH: 1.94-2.31 mm, TL/TW: 0.97-1.00, PL/PW: 0.46-0.47, EL/EW: 0.77-0.81.
Body roundish, moderately convex. Head bluish black, mouthparts yellow, only clypeal portion covered with short, greyish pubescence. Pronotum, scutellum and elytra bluish black (Fig. 1 a–d). Underside bluish black except legs yellow, abdomen brownish black, sparsely covered with short, grayish pubescence.
Head relatively large, 0.54-0.56 times pronotal width, punctures on frons large and moderately densely distributed, 0.5-2.0 diameters apart, surface polished between punctures. Eyes approximately oval, densely faceted, widest interocular distance about 0.46 times head width (Fig. 1 c–d). Pronotum 0.49-0.50 times elytral width, pronotal punctures large and unevenly distributed, similar to those on head, 1.0-3.5 diameters apart, lateral punctures sparser than those on disc, surface polished between punctures. Punctures on elytra large and densely distributed, 1.0-2.0 diameters apart, similar to those on pronotum. Elytral epipleura very wide, descending without groove. Abdominal postcoxal lines complete or almost complete, arcuate; posterior margin of male abdominal ventrite 5 weakly emarginate and ventrite 6 rounded; posterior margin of female abdominal ventrite 5 straight and ventrite 6 rounded (Fig. 2 a–c).
Male genitalia: penis slender, penis capsule with long outer arm and short inner one, apex of penis acute, screw-shaped from apical 1/11 to apical 2/11 (Fig. 2 d–e). Tegmen stout, penis guide narrow at base, widest at basal 1/3 then gradually converging to blunt tip, symmetrical in ventral view; widest at base gradually converging to blunt apex in lateral view. Parameres stout, slightly shorter than penis guide, densely covered with short setae at inner surfaces and a distal end in lateral view (Fig. 2 f–g).
Female genitalia: ovipositor with coxites elongate, approximately triangular, with large, subtriangular sclerite between coxites, 2/3 time as long as coxites (Fig. 2h); styli absent. Spermatheca oblong-oval, stout, with long and slender appendage at apex (Fig. 2i).
Distribution.
Motuo County, Tibet, China.
Etymology.
The species name is derived from Latin cornutus and refers to middle of clypeus with a horn-like projection in the male.
