Type material.

Holotype ♂ (MHUB): China, Yunnan, Gongshan County, No 12 Bridge [27.72°N, 98.60°E], 2750 m, Sino-America Exped, 15 June 2000, H. B. Liang leg.

Etymology.

Named after Dr. LIANG Hong-Bin, who collected several new species of Laena in China.

Diagnosis.

The new species is similar to Laena kalabi Schawaller, 2008, but can be easily distinguished from it by the following characters: (1) middle tibiae of male with finely hooked inner apex; (2) anterior and middle tibiae of male medially not sinuate, posterior tibiae of male apex not dilated; (3) shape of the aedeagus is different.

Description.

Male. Eyes (Fig. 5) elliptical, weakly prominent. Antennae (Fig. 41) extending to base of pronotum, ratio of length (width) of antennomeres II–XI as follows: 8.2 (8.5): 21.5 (8.3): 15.5 (8.5): 15.0 (10.0): 14.0 (10.1): 15.5 (11.0): 14.8 (11.0): 15.0 (11.8): 15.9 (13.0): 21.5 (14.0).

Pronotum (Fig. 5) quadrate, 1.0 times as wide as long, widest at middle; disc scattered with small punctures, their distance 1-6 times as long as puncture diameters, all punctures with setae slightly varying in length, surface nearly flat and dull, medial part of base feebly impressied, lateral margins indistinctly bordered, basal margin unbordered and not bent downwards, posterior angles rounded; propleura with larger punctures and shorter setae than those of disc.

Elytra (Fig. 5) nearly parallel-sided, 2.0 times as long as wide, widest at middle; punctural rows in indistinct striae, punctures as large as those on pronotum, and each bearing a shorter seta, intervals with very small punctures, each bearing a similar seta, all intervals flat and dull, interval IX with 3 indistinct setiferous umbilicate pores, interval VII with an indistinct setiferous pore in posterior region.

All femora (Figs. 42-44) without teeth. Middle tibiae (Fig. 43) with finely hooked inner apex, all tibiae (Figs. 42-44) with granulation from middle to apex at inner side.

Last abdominal ventrite (Fig. 45) truncate at apical margin. Aedeagus see Figs. 46-48.

Female: unkown.

Body length: 9.4 mm.
