Diagnosis.

Frons largely dark brown and reticulate-rugose (Figs 305, 318, 331); temples moderately angulate to rather rounded in dorsal view (Figs 303, 316, 329); distance from dorsally widened pale streak on temple to occipital carina in dorsal view more than width of streak (Figs 303, 316, 329); pronotum dark brown or blackish, transversely striate-rugose (Figs 300, 301, 313, 314, 326, 327); hind femur matt or with satin sheen, longer and largely coriaceous (Figs 309, 322, 335).

Description.

Redescribed from a female from Henan, length of body 13.4 mm, of fore wing 7.1 mm, and of ovipositor sheath 19.2 mm.

Head. Flagellum with 31 flagellomeres; frons coarsely reticulate-rugose (Fig. 331); three anterior coronal teeth large and acute, both posterior ones wider and arcuate; vertex flattened, largely rugose or rugulose, posteriorly transversely striate (Fig. 329); temple smooth and shiny (Fig. 330), rounded convex in dorsal view.

Mesosoma. Neck short and transversely carinate, anteriorly distinctly emarginated, posteriorly with transverse groove in dorsal view; pronotum largely striate or rugulose, posteriorly narrowly smooth (Figs 326, 327); propleuron largely coriaceous; mesopleuron coriaceous and with some shallow foveolae, anteriorly densely setose; scutellum aciculate medially and with round punctures laterally (Fig. 328); propodeum spaced foveolate and with coriaceous interspaces (Fig. 328); metapleuron coarsely reticulate-foveolate, convex medially.

Wings. Fore wing (Fig. 325): vein 1-M 1.4 times as long as vein 1-SR and 1.1 times vein m-cu; vein cu-a slightly antefurcal and subvertical; vein 2-SR 1.3 times as long as vein r; vein r ends 0.4 times length of pterostigma behind level of apex of pterostigma; vein 1-M and vein r distinctly curved; vein 1-SR 1.4 times as long as parastigmal vein; vein 3-CU1 largely nebulous, only basal 0.2 tubular.

Legs. Hind coxa robust, largely coarsely rugose; hind femur rugulose, ventrally with 2 large teeth and one smaller basal tooth (Fig. 335); hind tibia (Figs 335, 336) largely coriaceous and ventrally distinctly oblique carinate, 1.3 times as long as hind femur, basal narrow part of hind tibia about 1.2 times as long as widened part; ventral length of hind basitarsus 5.2 times as long as its width.

Metasoma. First tergite densely transversely striate, 7.5 times as long as its maximum width, 2.3 times second tergite and 0.9 times remainder of metasoma; second tergite basally rugose; remainder of metasoma largely smooth and shiny; pygidial area differentiated and with pair of truncate horns apically, pygidial impression distinct and reversed V-shaped (Fig. 334); ovipositor broken; length of ovipositor sheath about 1.4 times as long as body.

Colour. Largely blackish or dark brown; temple with yellowish streak along eye.
