Diagnosis.

Body mainly black with yellow pattern (Fig. 88), antennal scape partly yellow ventrally (Figs 89, 93), frontovertex with two yellow spots (Figs 89, 93), wings brownish, hind coxa with yellow patch baso-dorsally (Figs 88, 91), hind femur with yellow mark from base crossing to entire dorsal border and an obscure pale yellow stripe subventrally (Figs 88, 95), epipygium with a pair of slender longitudinal yellow stripes laterally (Figs 88, 92); hind femur with seven teeth ventrally, basal tooth short, second and third teeth acute apically, fourth teeth rather obtuse apically (Fig. 95); T1 with ovipositorial furrow (Fig. 92); ovipositor sheath long, at least reaching dorsellum (Fig. 92).

Redescription.

Female. Body length 8.5-9.5 mm. OOL= 1.3 POD; POL= 2.8 POD; MS= 2.1 POD.

Head. Coarsely and densely punctate (Figs 93, 94). Frons, lower face and clypeus with dense and short pubescence. Clypeus slightly produced ventrally. F2-F5 each distinctly longer than broad (Fig. 89).

Mesosoma. Pronotum, mesoscutum, mesoscutellum, dorsellum, mesopleuron, metapleuron, and propodeum with dense, moderate-sized punctures, and medium-sized pubescence (Figs 88, 90, 92). Pronotum with distinct premarginal carina. Dorsellum rounded posteriorly (Fig. 92). Hind coxa finely and densely punctate, with short pubescence, with obvious impunctate band (Fig. 91). Hind femur finely and densely punctate, with short pubescence; with seven tooth ventrally (including three long distinct slender teeth); basal tooth short, second and third teeth acute apically, fourth teeth rather obtuse apically (Fig. 95). Hind tibia produced into a spine ventro-apically (Fig. 95).

Metasoma. Metasoma with dense and moderate-sized punctures and short pubescence (Fig. 92). T1 narrower than T4 or T5 in dorsal view (Fig. 92). T1 with double ovipositorial furrow, subdivided by coarsely punctate ridge (Fig. 92). Ovipositor sheath long, at least reaching dorsellum (Fig. 92).

Colouration. Head predominantly black, with two elongate yellow spots on frontovertex (Figs 88, 93, 94). Antenna black, with scape partly yellow ventrally (Figs 89, 93). Pronotum black, with two yellow transverse stripes; anterior stripe is similar to and shorter than posterior one (Fig. 90). Mesoscutum black, with a pair of elongate yellow patches laterally, and without small rounded obscure pale yellow spots sublaterally (Fig. 90). Mesoscutellum black, with a curved yellow stripe posteriorly (Fig. 90). Dorsellum and mesopleuron black. Metapleuron black, with a yellow patch. Wings brownish. Fore and mid legs mostly black, with exception of yellowish brown tarsi, and connection between tibia and tarsi yellow. Hind coxa black, with yellow patch baso-dorsally (Fig. 91). Hind femur black, with yellow mark from base crossing to entire dorsal border, and an obscure pale yellow stripe subventrally; hind tibia blackish grown; hind tarsi brown (Fig. 95). T1 black, with two elongate longitudinal yellow marks laterad of ovipositorial furrow (Fig. 92); T2, T3 and T6 entirely black; T4 black, with yellow transverse band anteriorly; T5 black, with yellow transverse band posteriorly; epipygium with a pair of slender longitudinal yellow stripes laterally (Fig. 92).

Male. Not available for this study.

Variation.

One female from Xiangtoushan has some different colour patterns: mesoscutum with a pair of short yellow stripes laterally, and a pair of small rounded obscure pale yellow spots submedially; dorsellum mostly black, with a pair of pale yellow spots. Holotype of Leucospis ornatifrons has a yellow patch on mesopleuron.
