Surface of labroclypeus and disc of frons glabrous. Smooth area anterior to eye twice as wide as long. Eyes moderately large; ratio of diameter/interocular width: 0.6. Antennal club 1.2 times as long as remaining antennomeres combined. Ratio of length of metepisternum/metacoxa: 1/1.4.

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; basal group of dorsal spines of metatibia at first third of metatibial length.

Aedeagus. Fig. 3 A–C. Habitus: Fig. 3D.

Female unknown.

Variation.

Body length: 6.6-7.6 mm, length of elytra: 5.1-5.9 mm, width: 3.9-4.8 mm.

Diagnosis.

Tetraserica sigulianshanica sp. n. differs from the similar Tetraserica fikaceki sp. n. by the shape of parameres: the dorsal (= basal) lobe of the right paramere (in lateral view) is long, filiform, and strongly curved (Fig. 3A), the left paramere is much longer than that of Tetraserica fikaceki sp. n. (Fig. 2K, L).

Etymology.

The new species is named after its type locality, Sigulian Shan.
