Diagnosis of male. This new species is distinguished from other species of nominotypical subgenus; by having deeply emarginated S6 with strong setae in the bottom of emargination ( Fig. 5 View FIGURES 1 – 5. 1, 4 ); by having hypopygium basally without sharp differences between sclerotized and unsclerotized parts (Figs 22, 23 vs. 6–9), and by having black colored body ( Fig. 2 View FIGURES 1 – 5. 1, 4 ). FEMALE. Unknown.

Description. MALE. Body length 13.0–13.2 mm. Fore wing length 10.1–10.6 mm. Head width 1.1–1.2 × its height. Frons evenly convex. Ocelli small, POD: OOD 0.74–0.80 ×. Ratio of genal median length to eye median length (lateral view) 0.60–0.65 ×. Malar space (minimum value) 0.25–0.27 × pedicel width (lateral view). Clypeus longitudinally convex; anterior border weakly arcuately emarginated with thin rim. Labrum weakly convex, anterior border with weak median emargination. Mandible bidentate. Flagellomere 1 length 2.3 × its width. Relation of scape, pedicel and two first flagellomeres 44–45: 18–20: 53: 54–55. Mesosoma length dorsally 1.5–1.6 × its maximum width. Pronotum median length 0.3 × its median width, posterior pronotal border obtuse-angulated. Metanotum median length 2.25–2.27 × metapostnotum median length. Metapostnotum shiny with transversal striae. Propodeum evenly convex, its median length 0.80–0.85 × maximum width. Longer spur of mid and hind tibia 0.75 × mid and hind tarsomere 1 respectively. Fore claws asymmetrical with subbasal tooth, mid and hind claws symmetrical with subbasal tooth. Wings infuscate with darker apical part, venation as in Figs 44, 45. Pterostigma small, 1.5–1.7 × longer than first abscissa of R. Second abscissa of R 0.9–1.2 × third abscissa of R. Nervulus weakly postfurcal. Cu almost touch wing border. S6 deeply emarginated with short strong setae in the bottom of emargination ( Fig. 5 View FIGURES 1 – 5. 1, 4 ). S8 (hypopygium) with median carina, slightly convergent apically, basally without sharp differences between sclerotized and unsclerotized parts (Figs 22, 23). Genitalia as in Fig. 35 View FIGURES 28 – 35 .

Head (except gena), scape ventrally with dense long brownish erect setae; gena and pleurae with dense long erect setae; fore coxa, propodeum laterally and posteriorly with scattered long erect setae; pronotum, mid coxa, T1 laterally with scattered long erect setae; mesonotal scutum, scutellum, femora and S2–S5 with sparse erect setae; T7 apically with dense short and sparse longer erect setae. Body and legs with iridescent brown micropubescence. Body regularly micropunctate. Body and legs black; outer eye orbit near vertex with small pale patch; T2 basally indistinctly reddish in holotype.

Type material. Holotype, 3, Tajikistan: Gissarskii Mountain Ridge, Anzob Pass, 3600 m, 31.VII.1937 (Gussakovskij) [ ZIN]. Paratype, 1 3 with the same label as holotype [ IBSS].

Distribution. Tajikistan.

Etymology. The specific name is dedicated to famous Russian entomologist V.V. Gussakovskij ( 1904–1948), who was the expert in wasps and excellent collector.
