Diagnosis.

Tetraserica desalvazzai sp. n. is rather similar to T. gestroi , from which the new species differs by the left paramere being straight at base, and both parameres being generally more robust.

Etymology.

The new species is named after the collector, RV de Salvazza (noun in genitive singular).
