Type material.

Holotype:CHINA: Hainan Prov.: 1♀, Jianfengling N.R., Mingfenggu Valley, 18°44'N, 108°50'E, alt. 1000 m, 15.V.2011, Bi Wen-Xuan leg. (SNUC).

Description.

Body (Figs 3, 4) oval, convex, shining; length: 6.50 mm; width: 3.79 mm. Body black; legs, palpi and antennae reddish-brown. Elytron black, with red at basal third.

Head (Fig. 1) width between eyes = 5.5 times eye diameter in dorsal view; punctation coarse, separated by 0.5-1.0 puncture diameters laterally and 2-4 puncture diameters medially; stridulatory files not evident. Antennae (Fig. 5) short, not extending behind posterior border of pronotum; antennomere III about 2.0 times as long as IV; antennomeres IV to VIII short; antennomeres IX to XI broad and transverse; relative lengths of antennomeres II–XI: 9.0: 14.0: 7.0: 7.0: 7.0: 7.0: 6.5: 9.0: 9.0: 8.0. Maxillary terminal palpomeres trapezoidal, 1.67 times wider than long. Mentum broad with anterior projection, almost pentagonal, 1.75 times wider than long.

Pronotum transverse, convex above, widest at base (pl/pw = 0.70); anterior angles weakly projecting; lateral margins gently curved toward eyes. Pronotum distinctly punctured medially, finely and closely punctured laterally.

Prosternum (Fig. 7) strongly punctured, the front margin is produced to a short point in the middle, prosternal lines short, not extending in front of procoxal cavities; Mesosternum coarsely punctured. Metasternum coarsely punctured at the sides and almost smooth in the middle, with distinct coxal lines. Abdomen fairly strongly and closely, its sides coarsely, punctured, with distinct coxal lines on first ventrite nearly attaining posterior margin.

Scutellum pentagonal, finely and sparely punctured.

Legs short, tibiae triangular, with the extremities very broad and hollowed for the tarsi.

Elytra widest at middle, then gradually narrowing to apex; each with 9 punctate lines.

Female genitalia (Fig. 9) with gonostyli fringed apically with some elongate setae; female spermatheca (Fig. 6) with capsule almost egg-shaped.

Distribution.

China (Hainan Province).

Diagnosis.

The new species can be distinguished from other species in this genus by the black pronotum and red markings of the elytra.

Etymology.

This species is named in honor of Mr. Wen-Xuan Bi, collector of the new species.
