Epitranus crassicornis Boucek, 1982 Figs 95-96, 97-99

Epitranus crassicornis Bouček, 1982: 608-609 (♀, holotype, Laos (BPBM)).

Material.

1 ♀ (RMNH), "S. Vietnam: Dóng Nai, Cát Tiên N. P., Ficus trail, c. 100 m, 1-9.x.2005, Mal[aise] traps 1-8, C. v. Achterberg & R. de Vries, RMNH’05”; 1 ♀ (BPBM), "Vietnam, Vinh Long, 10.vi.1960, R.E. Leech".

Diagnosis .

This species comes near Epitranus erythrogaster Cameron in the key to species by Bouček (1982) and Narendran (1989), but differs from Epitranus erythrogaster in having: 1) malar space with few setae (in Epitranus erythrogaster malar space setose); 2) ♀ antenna usually short (in Epitranus erythrogaster antenna of ♀ always longer and slenderer); and 3) flagellum and pedicel combined only 1.1 × head width (in Epitranus erythrogaster flagellum and pedicel much longer than 1.1 × head width).

Description.

♀, length of body 3.5 mm.

Colour. Head (except mouth region) black; mesosoma rusty brown with ventral part black; metasoma dark brown; wings hyaline.

Head . Clypeus dorsally concave, pilose, its distal margin vaguely tri-lobed; face with fine sculpture, scrobal part mainly reticulate to finely cross striate; scrobal carinae converging at more acute angle and reaching anterior ocellus; head width 1.3 × its height in anterior view; POL 1.8 × OOL; pedicel plus flagellum 2.5 × as long as scape; scape not reaching anterior ocellus; F1 subquadrate; following segments slightly transverse; clava subconical, twice as long as broad, shorter than 3 preceding segments combined.

Mesosoma. Mesosoma with pilosity on mesoscutum and scutellum slightly golden; propodeum with percurrent median area delimited by distinct submedian carinae which are subparallel-sided.

Legs. Hind femur with 9-10 differently sized teeth on outer ventral margin.

Wings. Wings hyaline, pilosity on fore wing extensive, forming a hairline or steak directed obliquely basad from apex of STV.

Metasoma. Petiole about 6 × as long as broad; metasoma 1.3 × as long as petiole, 1.4 × as long as its height in lateral view and blunt apically.

Male. Unknown.

Host.
