Variation.

Length of body: 9.6-9.9 mm; length of elytra: 7.4-7.5 mm; maximum width: 6.0-6.1 mm.

Diagnosis.

Tetraserica tanahrataensis sp. n. is rather similar to T. mengeana Liu et al., 2014 in the general shape of the aedeagus; the new species differs by lacking trichome-like spines at the base of the right paramere, and the less strongly curved left paramere, which is nearly straight in the basal two thirds.

Etymology .

The new species is named after the type locality, Tanahrata (adjective in the nominative singular).
