Type material examined.

Holotype: ♂ "Coll. I. R. Sc. N. B., Cambodia, Kirirom N.P. 21.iv.2005 Pine forest, Light Trap, Leg. K Smets & I Var" (ISNB). Paratypes: 2 ♂♂ " Coll. I. R. Sc. N. B., Cambodia, Kirirom NP, 21.iv.2005, Pine forest, Light Trap, Leg. K Smets & I Var" (ISNB, ZFMK).

Description.

Length of body: 8.4 mm; length of elytra: 5.8 mm; maximum width: 5.4 mm. Surface of labroclypeus and disc of frons glabrous. Smooth area anterior to eye twice as wide as long. Eyes small, ratio of diameter/interocular width: 0.5. Ratio of length of metepisternum/metacoxa: 1/1.69. Metatibia short and wide, ratio width/length: 1/3.29; basal group of dorsal spines of metatibia at first third of metatibial length.

Aedeagus: Fig. 29 I–K. Habitus: Fig. 29L.

Female unknown.

Variation.

Length of body: 7.5-8.6 mm; length of elytra: 5.8-6.4 mm; maximum width: 5.0-5.9 mm.

Diagnosis.

Tetraserica kiriromensis sp. n. is rather similar to T. matsumotoi Kobayashi, 2017 in shape of aedeagus; the new species differs by the right paramere being distinctly shorter than median lamina of phallobase; also the apex of median phallobasal lamina is blunt and curved abruptly dorsally (rather than being straight and sharply pointed).

Etymology.

The new species is named after the type locality, Kirirom National Park (adjective in the nominative singular).
