Diagnosis.

Posterior half of pronotum comparatively low and dorso-posteriorly finely transversely rugose (Figs 366, 367); first subdiscal cell of fore wing comparatively robust and 2.0-2.5 times longer than wide (Fig. 365); first-third metasomal tergites black or dark brown (Fig. 375); first tergite irregularly coarsely transversely rugose (Figs 373, 375).

Description.

Redescribed after the male from Shaanxi (Liuba), length of body 9.8 mm, and of fore wing 6.5 mm.

Head. Flagellum with 27 flagellomeres; frons (Fig. 371) coarsely transversely rugose; three anterior coronal teeth large and acute, both posterior ones arcuate and lamelliform, with two small lobe-shaped carinae on each side in front of both posterior ocelli; behind level of coronal area having four curved, progressively smaller carinae followed by rugose area, rugae finer medio-dorsally and more or less reticulate laterally, posteriorly narrowly reaching occipital carina (Fig. 369); temple smooth and shiny except for some very small punctures ventrally, somewhat rounded in dorsal view (Fig. 370).

Mesosoma. Neck (Figs 366, 367) short and robust, irregularly carinate; middle pronotum largely smooth and with a distinct, somewhat sinuate carina posteriorly; posterior pronotum medio-dorsally smooth and laterally coarsely rugose; lateral oblique groove of pronotum rather narrow and smooth, ventral area below it obliquely striate; propleuron coriaceous; mesonotum (Fig. 366) irregularly foveolate and area between smooth; notauli and median groove indistinct; scutellum (Fig. 368) largely smooth medially, foveolate laterally and marginally; axillae rugose-foveolate; mesopleuron rather robust and distinctly convex, convex part rugose-reticulate and covered with whitish setosity, flat dorsal part sparsely carinate; mesosternum anteriorly rugose and posteriorly sparsely punctate; medially convex part of metapleuron reticulate-rugose and with short whitish setosity, antero-ventrally weakly crenulate, with dorsal anterior depression rather deep and ventral one less impressed; propodeum (Fig. 368) densely and irregularly rugose.

Wings. Fore wing (Fig. 365): vein 1-M distinctly curved, 2.4 times as long as vein 1-SR; vein r ends before level of apex of pterostigma; first subdiscal cell robust, twice as long as its maximum width. Hind wing (Fig. 365): vein cu-a largely pigmented.

Legs. Hind coxa (Fig. 372) robust, largely coarsely striate-rugose, with a small obtuse subapical dorsal tooth (but absent in other coxa); hind femur (Fig. 374) slender, granulate and covered with whitish, sparse setae, apically more or less strigate, ventrally with 3 acute teeth (the anterior one much smaller) and some denticles in between; hind tibia (Fig. 374) 1.1 times as long as hind femur, basal narrow part of hind tibia 0.5 times long as widened part, widened part ventrally distinctly obliquely carinate; length of hind basitarsus 3.7 times as long as its width.

Metasoma. First tergite (Figs 373, 375) robust, subcylindrical, 4.6 times as long as its maximum width, coarsely rugose, posteriorly more or less striate, laterally with whitish setosity; second tergite about as long as first tergite, smooth and finely sparsely punctate; remainder of tergites smooth and shiny; pygidial process distinct and tubular apically (Fig. 375).

Colour. Body colour varies from light brown to blackish; malar space yellowish; antenna, fore and middle legs and wing membrane light brown; frons, vertex, pronotum and first tergite dark brown; mesosoma, hind coxae blackish; temples, metasoma (except first tergite) and hind legs (except hind coxae) brown.

Female. See Madl (1991) for detailed description.

Distribution.

Palaearctic China (Shaanxi); North Korea.
