Variation.

Length of body: 7.5-7.8 mm; length of elytra: 5.6-5.8 mm; maximum width: 4.8-4.9 mm.

Diagnosis.

Tetraserica kollae sp. n. is very similar to T. brahmaputrae Ahrens, 2004 in the shape of the genitalia; it differs from it by having a wider dorsal lobe of the right paramere, which is inserted more laterally on the right side, as well as the more strongly curved distal lobe of the right paramere.

Etymology.

The new species is named after Dr Kolla Sreedevi, collector of the new species (noun in the genitive singular).
