Diagnosis.

Tetraserica yaoquensis sp. n. differs from all other species with straight posterior margin of metafemur by the short ventral process of the phallobasis being subequal to half of the length of phallobasis, right paramere being simple and basiventrally strongly widened towards apex, and left paramere having two lobes.

Etymology.

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