Diagnosis.

Tetraserica anhuaensis sp. n. differs in a number of characters from all so far known Tetraserica species: metafemur possessing a serrated continuous line beside anterior margin and fine sparse punctures with short setae behind line; the labroclypeus and frons having a few erect setae on disc; basal group of dorsal spines situated behind the middle of metatibia; metatibia beside dorsal margin in basal half with a blunt carina being partly finely serrate.

Etymology.

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