Diagnosis.

Tetraserica maoershanensis sp. n. is in the external shape and morphology of the male genitalia similar to Tetraserica daqingshanica and Tetraserica sculptilis . It differs by the shape of the parameres: the dorsal lobe of the right paramere is short and does not exceed the length of the ventral lobe (Fig. 2C).

Etymology.

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