Body length: 8.9 mm, length of elytra: 7.2 mm, width: 5.7 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: 0.5. Antennal club 1.2 times as long as remaining antennomeres combined. Ratio of length of metepisternum/metacoxa: 1/1.6. Metafemur dull, anterior margin acute, without submarginal serrated line; anterior row of setae-bearing punctures absent; posterior margin with a large sharp hook.

Variation.
Body length: 8.9-9.8 mm, length of elytra: 7.1-7.2 mm, width: 5.5-5.7 mm.
Diagnosis.
Tetraserica graciliforceps sp. n. differs from Tetraserica longzhouensis by the following features: phallobasis in dorsal view is only slightly asymmetric; left and right parameres are simple, without two lobes; posterior angles of the pronotum are strongly rounded.
Etymology.
The species name is derived from the combined Latin words, gracilis - fine, and forceps - forceps, with reference to the fine and simple parameres of the species.
