Variation.

Body length: 6.8-7.7 mm, length of elytra: 5.0-5.6 mm, width: 4.0-4.6 mm.

Diagnosis.

Tetraserica leishanica sp. n. is similar to Tetraserica anhuaensis externally and in the shape of male genitalia. Tetraserica leishanica differs by the reddish brown body colour, more slender metatibia (ratio length/width:>3.6), longer metacoxa. It also differs by the shape of the parameres: the left paramere is straight behind the base (while it is curved in Tetraserica anhuaensis ), with a long basal lobe (basal lobe in Tetraserica anhuaensis is short); the right paramere is more strongly curved externally at apex than in Tetraserica anhuaensis .

Etymology.

The new species is named after its type locality, Leishan.
