Type material.

Holotype. ♂, China, W Henan, 9.-10.VI. / Funiu Shan [伏牛山], 33°31'N, 111°56'E / BAOTIANMAN, 1500-1750 m / Jaroslav Turna leg., 2008 (CPMG). Paratypes. 1♀, same data as holotype (CJRZ); 1♂, same data as holotype except: 15.V.-5.VI / 2009 (CMPR).

Diagnosis.

Aedeagus (Fig. 7A) very short and stout, with median lobe gradually narrowing towards a widely lanceolate apex and terminated to a rounded knob in dorsal view. In lateral view (Fig. 7B), median lobe very thick, gently bent ventrally, and gradually tapering towards a thin apex.

Description.

Male. EBL: 3.9 mm. Length of different body parts: HL: AL: PL: ELL = 0.6: 1.0: 1.1: 2.1 mm; width: HW: EW: PW: ELW = 1.0: 0.1: 1.5: 1.6 mm. Proportion of antennomeres from base to tip in μm (length × width): 154 × 61, 117 × 61, 87 × 65, 55 × 72, 57 × 87, 46 × 100, 80 × 117, 34 × 124, 77 × 138, 89 × 146, 141 × 131.

Habitus (Fig. 1F) elongated oval, regularly convex and sublustrous. Well pigmented: mostly blackish brown; mouthparts, basal three or four antennomeres and apical half of ultimate antennomere, protarsi, and apex of meso- and metatarsi more or less paler. Dorsum continually clothed with fine, recumbent, yellowish pubescence. Insertions of pubescence on dorsal surfaces of pronotum, elytra and femora aligned along transverse striolations; interspace between two striolations glabrous.

Head quite transverse, HW/HL = 1.7. Clypeofrontal suture absent. Clypeus with anterior margin gently rounded. Compound eyes well developed, EW/HW = 0.1. Antennae (Fig. 6A) slender, AL/HW = 1.0; antennomere III shorter than II; VI with length/width = 0.5; XI pear-shape.

Pronotum (Fig. 6B) transverse, widest directly before hind angles, PW/PL = 1.5. Sides gently arched, narrowing from posterior to anterior; hind angles slightly projected backwards and acute. Posterior margin widely protruded in middle part, emarginate near hind angles.

Elytra oval, widest at about basal 1/5, ELL/EW = 1.3. Sides weakly arched, gradually narrowing from widest part to apices; apices (Fig. 6G) widely rounded. Sutural striae present. Metathoracic wings fully developed.

Prolegs robust, with basal three protarsomeres (Fig. 6C) less expanded: TW/BTW = 1.5. Protibiae (Fig. 6E) expanded towards apex. Profemora broad. Mesotibiae arcuate, mesotarsi simply linear. Metatibiae slender and straight.

Abdominal ventrite VIII (Fig. 6I) simply subrounded at posterior edge. Spiculum gastrale of genital segment (Fig. 6J) with about 1/3 of length protruding beyond anterior edge of epipleurite IX.

Aedeagus (Fig. 7A) very short and stout, with median lobe gradually narrowing towards a widely lanceolate apex and terminated to a rounded knob in dorsal view; opening of genital orifice situated on dorsal surface, deeply cut inwards on preapical left margin of median lobe. Ventral surface of the apex of the median lobe (Fig. 7C) inserted with 5 ventrally oriented setae on the left side and 6 ventrally oriented setae on the right side; parameres narrow, reaching about apical 1/5 of median lobe, each apex (Fig. 7D) with 2 lateral setae and 1 similar apical seta. In lateral view (Fig. 7B), median lobe very thick, gently bent ventrally, and gradually tapering towards a thin apex. Endophallus with stylus quite slender, a subelliptical nodule in middle region, a cheliform complex just below base of stylus, and a circular complex in the basal region.

Female. Similar to male in general appearance (Fig. 1G), including elytral apices (Fig. 6H), but distinguished by the following characteristics: protarsi (Fig. 6D) simply linear; protibiae (Fig. 6F) slightly narrower; abdominal ventrite VIII (Fig. 7E) round at posterior edge; genital segment and ovipositor as shown in Fig. 7F; spermatheca (Fig. 7F) curved in distal part, coiled in proximal part, and stem slightly arcuate.

Distribution.

China (Funiu Mts. in Henan).

Etymology.

The specific epithet is from the Chinese name (in Pinyin) of the type locality "Funiu Shan", and means "prostrate cow".
