Etymology.

Named after the type locality.

Diagnosis.

The new species is similar to Laena hingstoni Schuster, 1926, both from Xizang, by similar body shape, but can be separated by the smaller body size, the completely unbordered lateral margin of the pronotum, and flat elytral intervals.

Description.

Male. Eyes (Fig. 2) rounded, moderately prominent. Antennae (Fig. 15) extending to base of pronotum, ratio of length (width) of antennomeres II–XI as follows: 7.0 (4.8): 10.8 (5.0): 7.5 (5.3): 8.0 (5.5): 10.0 (5.4): 8.9 (6.3): 9.5 (6.8): 10.0 (7.0): 10.0 (8.0): 14.9 (8.2).

Pronotum (Fig. 2) cordiform, basal margin distinctly narrower than anterior margin, 1.2 times as wide as long, widest just behind anterior margin; disc scattered with some punctures, their distance 2-5 times as long as puncture diameter, all punctures with setae slightly varying in length, surface flat and shining, lateral margins unbordered, basal margin unbordered and not bent downwards, posterior angles rounded; propleura with smaller punctures and shorter setae than those of disc.

Elytra (Fig. 2) oblong ovate, 1.7 times as long as wide, widest at middle; punctural rows without striae, punctures as large as those on pronotum and each bearing a seta, intervals with very fine punctures, each bearing a seta longer than those of punctures of rows, all intervals flat and shining, interval IX with 3 setiferous umbilicate pores.

All femora (Figs. 16-18) without teeth. All tibiae (Figs. 16-18) normal.

Last abdominal ventrite (Fig. 19) triangular at apex. Aedeagus see Figs. 20-22.

Female: unkown.

Body length: 4.3-5.0 mm.
