Paratypes: 2 ♂♂, 1 ♀ [China] "Nankai Mingya, Baisha, Hainan, 25-26.V.2008, 450m, leg. Ba Yibin, Lang Juntong" (HBUM, ZFMK), 1 ♂ [China] "East of Mts. Bawangling, Changjiang, Hainan, 5-7.VI.2008, 750m, leg. Ba Yibin, Lang Juntong" (HBUM).

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).
