Diagnosis.

Tetraserica rubrithorax sp. n. differs from all other known Tetraserica species by having the body blackish brown and pronotum reddish.

Etymology.

The species name (noun in apposition) is derived from the combined Latin words rubus (red) and thorax, with reference to the red pronotum of the species.
