Diagnosis.

Tetraserica longipenis sp. n. differs from Tetraserica yaoquensis by the smaller body, shorter antennal club, and the right paramere being simple, long and narrow.

Etymology.

The species name is derived from the combined Latin words, longus - long and penis - male copulation organ, with reference to the long parameres of the species.
