Diagnosis.

Body length in male 6.0–6.6, in female 6.1–7.1; frons protruding above clypeus base (as in Fig. 1 C); labium reaching middle coxa, but not surpassing it (as in Fig. 1 N); hind femur distinctly tapering towards apex, without spines (Fig. 2 B), 6–8 × as long as wide; hind tibia curved basally (as in Fig. 2 I); swelling on propleura curved (as in Fig. 1 H); antennal segment I length / head width ratio in male 1.0, in female 0.8–1.0; antennal segment I / pronotum length ratio 0.6–0.7 in male, 0.6–0.8 in female; antennal segment I not widened basally, its setae at base as dense as on other parts of this segment; setae in antennal segment I simple; antennal segment II length / head width ratio in male 2.4–2.6; groove on posterior part of mesopleuron absent (as in Fig. 1 M); paired pits between calli absent (as in Fig. 1 G); setae on posterior margin of hind femur denser than on other parts of femur, shorter than half of hind femur width (Fig. 2 B); genital capsule only slightly longer than wide, acute apically, with outgrowth near left paramere socket (Fig. 5 R); right paramere ~ 4 × as long as wide, its apical part as wide as basal part, apical process bifurcate (Fig. 5 E, G); right paramere with apical process acute in posterior view (Fig. 5 Р), its sensory lobe swollen (Fig. 5 F); vesica with four membranous lobes (Fig. 7 G – I); membranous swelling on dorsal labiate plate not covering sclerotized rings (Fig. 10 C); posterior wall with dorsal structure and sigmoid process between interramal lobes, dorsal structure rounded (Fig. 10 D).

Distribution.

Stenodema virens is widely distributed in Europe, the Near East, and the Caucasus, extending eastwards to Yakutia, Buryatia, Mongolia, and northern China (Kerzhner and Josifov 1999).
