Description.

Length of body: 9.6 mm; length of elytra: 7.4 mm; maximum width: 6.1 mm. Surface of labroclypeus and disc of frons glabrous. Smooth area anterior to eye twice as wide as long. Eyes small, ratio of diameter/interocular width: 0.53. Ratio of length of metepisternum/metacoxa: 1/1.48. Metatibia short and wide, ratio width/length: 1/3.25; basal group of dorsal spines of metatibia at first third of metatibial length.

Aedeagus: Fig. 23 A–C. Habitus: Fig. 23D.

Female unknown.

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).
