Diagnosis.

The new species differs from Tetraserica damaidiensis in the shape of the parameres: the left paramere is straight instead of being curved dorsally (Fig. 3I), the right paramere is slender in dorsal view, lacking the basal dorsal tooth (Fig. 3J) which is present in Tetraserica damaidiensis .

Etymology.

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