Diagnosis.

Tetraserica phukradungensis sp. n. differs from T. trilobiforceps sp. n. species by the shorter and stouter left paramere which has a short fine dorsal lobe behind the middle (rather than before the middle as in T. trilobiforceps ).

Etymology.

The new species is named after the type locality, Phu Kradung (adjective in the nominative singular).
