Description.

Body length: 7.5 mm, length of elytra: 5.5 mm, width: 4.6 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: 0.48. Antennal club 1.1 times as long as remaining antennomeres combined. Ratio of length of metepisternum/metacoxa: 1/1.48. Metafemur dull, anterior margin acute, without submarginal serrated line; anterior row of setae-bearing punctures absent; posterior margin straight, without blunt tooth. Metatibia short and wide, ratio width/length: 1/3.3; basal group of dorsal spines of metatibia at first third of metatibial length.

Female unknown.

Diagnosis.

Tetraserica longzhouensis sp. n. differs from all other species with straight or slightly convex posterior margin of metafemur by the small eyes, short ventral process of phallobasis being at maximum subequeal to half of the length of the phallobasis, strongly asymmetric phallobasis (dorsal view), right paramere being simple, and left paramere having the ventral lobe shorter than the dorsal one.

Etymology.

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