( Figs 14–19 )

Type material. Holotype female (body on card, antenna and fore wing on slide). China: Hainan, Tien Fong Mts. [Jian Feng Mountains], 20 May 1983 (coll. Zdenĕk Bouček) (NHM).

Female. Body length 0.87 mm. Colour. Head and mesosoma metallic blue-black, gaster mostly dark to black, except T1 and T2 yellow-brown to dark brown ( Fig. 14 ). Antennal scape with basal half pale brown and apical half white; pedicel mostly white with a dark brown spot basally; 2 anelli dark brown; funicle and clava brown to dark brown ( Fig. 16 ). Fore wing hyaline, with pale brown cloud below stigmal vein ( Fig. 17 ). Legs with coxae and femora mostly dark brown to blue-black, tibiae with basal half dark brown and apical half white, tarsi white except tarsal claws brown to dark brown.

Head. Head transverse, slightly wider than mesosoma. Antenna ( Fig. 16 ) with 2 anelli, each wider than long; scape about 3.25× as long as wide; pedicel 1.52× as long as wide, distinctly longer than each segment of flagellum (relative measurements: 70: 41: 37: 26: 52) respectively; flagellum short, the single funicular segment wider than long (41: 52); claval segments with relative lengths: 37: 26: 52 and relative widths: 64: 54: 32; C3 conically produced at apex into a spine, conic-ovate, distinctly shorter than the long pedicel (52: 70); flagellar segments with relatively long setae.

Mesosoma. Mesoscutum and scutellum with very deep and rather elongate-meshed engraved reticulation, except mesoscutum anterolaterally with fine-meshed engraved reticulation; mesoscutum with one pair of setae medially, scutellum with one pair of long setae anteriorly ( Fig. 15 ). Fore wing ( Fig. 17 ) broad, 1.85× as long as wide, basal half of wing mostly asetose; marginal fringe 0.10× as long as width of wing disc; marginal vein with 9 long setae along anterior margin and with a long seta at base of parastigma (broken off in Fig. 18 ); stigmal vein with a slender neck and expanded apex, with 4 sensilla arranged in a longitudinal row ( Fig. 19 ); postmarginal vein absent ( Fig. 19 ).

Metasoma. Gaster short, about 0.64× as long as mesosoma. T7 small. Ovipositor not projecting beyond apex of metasoma.

Male. Unknown.

Host. Unknown.

Distribution. China (Hainan: Jian Feng Mountains).

Etymology. The new species is named in honour of the late Dr Zdenĕk Bouček, who collected the type specimen.

Diagnosis. Baeoentedon bouceki sp. nov. is distinguished from other species of Baeoentedon by the following: antenna with basal half of scape pale brown, and apical half white, pedicel mostly white with a dark brown spot basally, funicle and clava brown to dark brown ( Fig. 16 ); gaster mostly dark, except T1 and T2 yellow-brown to dark brown ( Fig. 14 ); fore wing with pale brown cloud below stigmal vein ( Fig. 17 ); and gaster short, about 0.64× as long as mesosoma.
