Diagnosis.

Tetraserica wangtongensis sp. n. is in the external shape and morphology of the male genitalia similar to Tetraserica daqingshanica and Tetraserica sculptilis . It differs by the lacking tooth at the posterior margin of metafemur and in the shape of the parameres: the right paramere is straight (in dorsal view) and not curved as in Tetraserica daqingshanica and Tetraserica sculptilis (Fig. 1J).

Etymology.

Tetraserica wangtongensis sp. n. is named after its type locality, Wang Tong.
