Type specimen examined.

Holotype: ♂, China, Xizang, Mangkang, Haitong; 3250 m; Aug. 1982; Shuyong Wang leg.; IZAS.

Description.

Male. Length 6.0 mm, width 3.4 mm.

Head, pronotum and scutellum blackish green, antennae, elytra, legs, and ventral surface of body brown; elytral epipleuron from base to subapex yellow, with middle of suture yellow, connected by yellow stripes from the base to the apex of each elytron.

Vertex finely and sparsely covered with punctures; frontal tubercles distinctly raised, each separated by a deep furrow; antennae short, robust, extended to the middle of the elytra; antennomeres 1-3 thin, shiny; antennomeres 4-11 wide and flat, with short hairs, antennomeres 2 and 3 shortest, antennomere 3 similar in length and shape to antennomere 2, antennomere 4 longest, 1.5 × as long as antennomeres 2 and 3 combined; antennomeres 5-10 gradually shortened, shorter than 4; antennomere 11 slightly longer than 10, pointed.

Pronotum approximately 1.8 × as wide as long, with rounded lateral margins; disc slightly convex, sparsely covered with small punctures in the middle with large punctures on other parts. The interstices between punctures equal to the diameter of individual punctures and lightly covered with small punctures in interstices.

Scutellum triangular, sparsely covered with punctures at base.

Bases of both elytra wider than the pronotum, gradually widen posteriorly, and rounded at apex; dorsal surface slightly convex, irregularly covered with large and deep punctures, the interstices between punctures narrower than the diameter of individual punctures and lightly covered with small punctures in interstices, with their interstices somewhat wrinkled.

Metasternum twice as long as mesosternum; prothoracic legs shortest, mesothoracic legs slightly longer, metathoracic legs longest.

Ventral surface of abdomen with five segments, segment 1 longest, segments 2-4 gradually shortened, apical segment slightly longer than segment 4, three lobes.

Aedeagus slender, rounded laterally, basally widened, with triangular apex, distinctly pointed. In lateral view moderately bent.

Differential diagnosis.

This species can be distinguished from other species by blackish green pronotum, yellow stripes of elytra and large punctures on elytra.
