Description.

Body length: 9.7 mm, length of elytra: 7 mm, width: 6 mm.

Surface of labroclypeus and disc of frons glabrous. Smooth area anterior to eye twice as wide as long. Eyes moderately large; ratio of diameter/interocular width: 0.6. Antennal club 1.2 times as long as remaining antennomeres combined. Ratio of length of metepisternum/metacoxa: 1/1.8. Metafemur dull, anterior margin acute, without submarginal serrated line; anterior row of setae-bearing punctures absent; posterior margin straight, without blunt tooth. Metatibia short and wide, ratio width/length: 1/2.7; basal group of dorsal spines of metatibia at first third of metatibial length. Aedeagus. Fig. 2 E–I . Habitus: Fig. 2J.

Diagnosis.

Tetraserica fikaceki sp. n. is in the external shape and morphology of the male genitalia similar to Tetraserica wangtongensis . It differs by the shape of the parameres: the dorsal lobe of the right paramere (in lateral view) is curved ventrally (while being straight in Tetraserica wangtongensis) (Fig. 2I), the left paramere is reduced in size (Fig. 2E).

Variation.

Body length: 8.0-9.7 mm, length of elytra: 6.0-7.0 mm, width: 4.8-6 mm. Head of the female paratype is missing.

Etymology.

The new species is named after one of the collectors of the type series, Martin Fikáček (Prague).
