Diagnosis.
Body length in male 6.1–6.8, in female 6.6–7.3; frons protruding above clypeus base (Fig. 1 H, I); labium reaching middle coxa (as in Fig. 1 N); hind femur distinctly tapering towards apex, without spines, not enlarged, 6–8 × as long as wide (Fig. 2 C); hind tibia curved basally (Fig. 2 I); swelling on propleura curved (Fig. 1 H); antennal segment I length / head width ratio in male 1.0, in female 0.9–1.0; antennal segment I length / pronotum length ratio 0.7–0.9 in male, 0.7 in female; antennal segment I not widened basally, its setae at base as dense as on other parts of this segment; setae of antennal segment I simple; antennal segment II length / head width ratio in male 3.1–3.5; 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 C); genital capsule only slightly longer than wide, acute apically, with outgrowth near left paramere socket (Fig. 6 Q); right paramere ca 3 × as long as wide, its apical part as wide as basal part, apical process not bifurcate (Fig. 6 A); left paramere with apical process acute in posterior view (Fig. 6 D), its sensory lobe swollen (Fig. 6 B); vesica with four membranous lobes (Figs 7 E, F, 8 A); dorsal labiate plate as long as wide, sclerotized ring 2–3 × as long as wide; distance between sclerotized rings 4 × as long as sclerotized ring width; membranous swelling on dorsal labiate plate not covering sclerotized rings (Fig. 10 A); posterior wall with dorsal structure and sigmoid process between interramal lobes, dorsal structure oval (Fig. 10 E).
Distribution.
Stenodema turanica is known from the Balkans, Caucasus, Turkey, Iraq, Iran, Central Asia, Mongolia, and northwestern China (Kerzhner and Josifov 1999).
Notes.
Stenodema turanica was originally described (Reuter 1904) from the type series collected by K. O. Ahnger and A. P. Fedchenko in Central Asia and retained at the Finnish Museum of Natural History (MZH). Due to the observed similarity of S. turanica with S. virens, here we designated the lectotype for Stenodema turanicum Reuter, 1904, the male from Kopet Dagh mountains in Turkmenistan (Fig. 8, http://id.luomus.fi/GZ.56573).
Stenodema turanica and S. virens are very similar externally. According to Wagner (1974), in S. turanica antennal segment II is twice as long as segments III and IV combined, whereas in S. virens this segment is only 1.5 × times as long as segments III and IV combined. Additionally, the setae on the inner margin of hind femur are inclined in S. virens, whereas they are straight in S. turanica. The setae on the hind femur are more or less the same in both species (Fig. 2 B, C). We confirm that the antennal segment II is longer in males of S. turanica rather than in males of S. virens, in particular, antennal segment II / head width ratio is 3.1–3.5 in S. turanica and 2.4–2.6 in S. virens. However, we were unable to find reliable differences in female measurements. These two species differ from each other in both, male (compare Fig. 7 D – F and Fig. 7 G – I) and female (compare Fig. 10 A, E and Fig. 10 C, D) genitalia.
