Variation.

Length of body: 8.9-10.2 mm; length of elytra: 6.8-7.1 mm; maximum width: 5.4-5.8 mm.

Diagnosis.

Tetraserica finociliata sp. n. differs from all other Tetraserica species by the long and robust distal lobe of right paramere being strongly curved upwards (lateral view), and having a strong subapical ventral tooth.

Etymology.

The species name (adjective in the nominative singular) is derived from the combined Latin words fino- (fine) and ciliatus (ciliate), with reference to the fine comp of trichomes at the base of the right paramere.
