Figs 1, 4, 5

TYPE MATERIAL. Holotype – ♂, China : Shaanxi province, with labels “ CHINA Shaanxi Qin Ling Shan 108.47 E, 33.51 N, Mountain W Pass at autoroute km 70, 47 km S Xian 2300–2500 m, sifted 26- 30.08.1995, leg. A. Pütz ”. (cMSch). GoogleMaps

DESCRIPTION. Length of body 6.3 mm, pronotum width 1.14 mm, shoulder width 1.2 mm. Body flattened, integument strongly shining. Body colouration black, legs and antennae dark brown (Fig. 1).

Head slightly transverse, ratio of its length (from base to anterior margin of clypeus) to maximum width (mm) about 0.72: 0.94. Head widest across eyes. Eyes moderately large, slightly convex. Frons rather finely and sparsely punctate; vertex with much coarser, larger and denser punctation. Diameter of punctures on vertex more than twice that on front, interspaces significantly shorter than diameter of punctures. Antennae rather long. Antennal segment 1 elongate, cylindrical, more than twice as long as its maximum width; segment 2 elongate, conical, about twice as long as its maximum width, much shorter and narrower than segment 1; segment 3 conical, similar in structure to segment 2; segments 4–6 cylindrical, slightly widened to apex, only slightly longer than their maximum widths; segments 7–10 conical, much more massive than segments 4–6, slightly transverse; segment 11 pointed apically, about 1.5 times as long as wide. Last 5 segments form loose club.

Figs 1–3. Holotypes of Coprophilus . 1 – C. qinlingensis sp. n., body, dorsal view; 2, 3 – C. formosanus : 2 – body, dorsal view; 3 – labels.

Pronotum slightly convex, with maximum width about 2/3 its length from base. Ratio of pronotum length to its maximum width (mm) about 0.89: 1.14. Front angles rounded, lateral margin serrated. Pronotal disc with deep depressions: 2 paired oval depressions at base, on either side of midline; unpaired triangular depression at disc centre and 2 wide depressions near lateral margins. Pronotal disc with coarse, large and rather dense punctation, diameter of punctures slightly smaller than on vertex. Punctation densest at basal angles and at bottom of depressions near lateral margins, interspaces between these punctures much smaller than their diameter.

Elytra flattened, ratio of length of elytra to their combined width (mm) about 1.23: 1.53. Surface of each elytron with 6 deep well-defined grooves formed by fused punctures. Diameter of punctures approximately the same as on pronotum. Ridges between grooves smooth and strongly shining. Elytra finely bordered.

Abdomen very delicately shagreened.

Aedeagus of characteristic structure ( Figs. 4, 5 View Figs 4–8 ).

FEMALE. Unknown.

DISTRIBUTION. Central China, Shaanxi province.

ETYMOLOGY. This species is named after the type locality.

DIAGNOSIS. The new species is similar to Coprophilus formosanus in body colouration and microsculpture, but differs from latter by having deeper depressions on the pronotal disc, by a larger and denser punctation on the vertex and on the lateral margins of the pronotum. Both species are easily distinguishable by the structure of the aedeagus ( Figs. 4, 5 View Figs 4–8 vs Figs. 6–8 View Figs 4–8 ).
