Diagnosis.

Head transverse in dorsal view and elliptical in lateral view (Fig. 172); vertex transversely rugose, posteriorly more coarsely (cf. Fig. 165 of Foenatopus maculiferus ); frons densely and coarsely rugose; posterior half of pronotum dorsally finely superficially reticulate (cf. Fig. 161 of Foenatopus maculiferus ); propodeum sparsely and superficially foveolate (Fig. 173); pterostigma short and apically obtuse (Fig. 168); vein 2-CU1 of fore wing nearly absent; hind femur swollen (Fig. 171) and with two large teeth ventrally and central large teeth whitish; third tergite entirely dark brown or blackish; ovipositor sheath largely dark brown and apically blackish (Chao, 1964) (ovipositor sheath lost in holotype in Beijing).

Description.

Holotype, female, length of body 7.4 mm, of fore wing 4.6 mm, and of ovipositor 6.8 mm.

Head. Frons finely transversely striate (cf. Fig. 167 of Foenatopus maculiferus ); three anterior coronal teeth acute, both posterior ones wide and arcuate; vertex with 3 carinae between posterior ocelli, followed by coarsely transversely striate-rugose area (cf. Fig. 165 of Foenatopus maculiferus ); head transverse in dorsal view; temple smooth and shiny (Fig. 172).

Mesosoma. Neck (Figs 169, 170) elongate and moderately robust, transversely striate, not differentiated from middle part; pronotum rather robust, transversely strigate; posterior part of distinctly convex laterally; propodeum sparsely and shallowly foveolate, posterior part somewhat rugose (Fig. 173).

Wings. Fore wing (Fig. 168): wing membrane hyaline; vein 2-CU1 nearly absent; pterostigma comparatively short and rounded apically, about 1.9 times as long as vein r and about 7 times its maximum width; vein r ends about 0.2 times length of pterostigma behind level of apex of pterostigma; vein SR1 nearly parallel to costal margin, vein SR1 and vein r obtusely angled.

Legs. Hind coxa rather slender, annularly transversely striate; hind femur (Fig. 171) finely transversely striate, ventrally with 2 large whitish teeth, basal obtuse tubercle present (and dark brown, same colour as hind femur); hind tibia coriaceous and apically densely setose.
