Diagnosis.

Tetraserica phoupaneensis sp. n. is similar to T. vietnamensis (Frey, 1972); the new species differs by the left paramere being as long as phallobase and by the right paramere having a longer basal lobe which is directed distally. In T. vietnamensis the left paramere is only half as long as phallobase, and the right paramere has no basal lobe.

Etymology.

The new species is named after the type locality, Mt Phou Pane (adjective in the nominative singular).
