Diagnosis.

Tetraserica sculptilis sp. n. is in the external shape and morphology of the male genitalia very similar to Tetraserica daqingshanica . It differs only in the shape of the parameres: the left paramere is more narrow in Tetraserica sculptilis sp. n., its dorsal margin weakly and evenly curved (Fig. 1E).

Etymology.

From the Latin word sculptilis - modelled, sculptured, with reference to the shape of the aedeagus.
