Kuatunia wolongensis Tshernyshev, 2012 sp. n.

( Figs. 8–11 , 14 )

Type material. Holotype, male: СHINA: Central Sichuan, Wolong Nature Reserve, h~ 500–1700 m a.s.l., 31°02'N – 103°11'E, 15–24.V.1994, S. Kurbatov leg. (SCH).

Description. Holotype, male ( Fig. 8 ). Body elongate, parallel.

Head black with yellow mouthparts. Antennae dark, with segments 1–4 yellow, outer sides dark brown. Pronotum yellow-orange, scutellum yellow-orange with black tip, elytra completely black. Underside dark with yellow prothorax; legs black with anterior and intermediate tarsi and apices of femora paler. Apices of femora; coxae and trochanters dark, except tips at joining place. Surface evenly covered with dense, fine and depressed goldish pubescence. Vesicles yellow; thoracic mesepimera brown.

Head narrower than pronotum, of same width at level of eyes; front slightly impressed; genae short and straight; clypeus narrow, transverse, straight; labrum short, transverse; palpi simple with cylindrical apical segment; surface of head slightly shining, densely punctured with distinct microsculpture, pubescence dense, short and depressed.

Antennae filiform, 1.6 mm long, reaching the middle of the elytra; segment 1 clavate, segment 2 small, rounded; remaining segments cylindrical, segment 11 longer than segment 10 and as long as first segment, evenly sinuate at apex; surface evenly covered with short, light erect pubescence.

Pronotum transverse, anterior margin strongly convex; posterior margin straight; lateral sides sinuate just behind the middle, evenly rounded before; surface densely punctured, with distinct microsculpture, semi-shiny, with fine depressed light pubescence.

Scutellum small, rectangular, longitudinal, almost completely covered by pronotum, densely punctured and covered with sparse pubescence, shining.

Elytra oblong, subparallel, very slightly widened posteriorly, at base somewhat wider than pronotum; humeri distinct, but not protruding; apices sinuate and truncate, completely impressed dorsally, with concave and impressed plate apically ( Fig. 9 ); surface semi-shining, densely punctured, and covered with dense, short, fine depressed pubescence.

Hind wings developed normally.

Legs moderate in length, thin and elongate; posterior femora almost reaching the elytral apices; tibiae thin, straight; femora slightly compressed; all tarsi 5-segmented, narrow, the second segment in anterior tarsi with the above referred comb; claw-segment the longest, two times longer than the 1st segment in anterior tarsi, equal to 1st plus 2nd combined in intermediate, and only slightly longer than the 1st segment in posterior tarsi; claws narrow, short with a membrane at base.

Ventral body surface densely punctured, with sparse, fine, depressed pubescence and distinct microsculpture; apical tergite longitudinal, distinctly elongate and sinuate just behind the middle, evenly rounded at the tip ( Fig. 10 ); apical sternite transverse, 1.1 times wider than long, evenly sinuate at apex and deeply emarginate at the middle ( Fig. 11 ); aedeagus simple, without spines or denticles in the internal sack, elongate, with a slightly stretched and dorsally curved lamella ( Fig. 13 ); tegmen with thin parameres ( Fig. 12 ).

Length 2.5 mm, width (at elytral base) 0.9 mm.

Female unknown.

Etymology. This species is named after the type locality, Wolong Nature Reserve ( China).

Habitat. The male was collected on an old tree trunk and, probably, the species inhabits subtropical forests. Further details of its bionomy remain unknown.

Distribution. China, Central Sichuan ( Fig. 14 ).
