( Figs 11, 12 , 44 , 63 , 83 , 105)

Arachnospila (Ammosphex) kurzenkoi Lelej, 1995: 245 , 3 (holotype, 3, Irkutsk Prov., Angarsk, 11.VI.1983 (Nemkov) [IBSS], examined).

Diagnosis of male. The male of this species is easily distinguished from other males of Arachnospila (Ammosphex) abnormis -species group (hypopygium ventro-preapically with tuft of long erect setae medially) by having hypopygium with two rows of soft setae (not bristles) baso-laterally ( Figs 11, 12 vs. 1–10). Genitalia as in Fig. 44 .

Diagnosis of female. The female of this species is similar to that of Arachnospila (Ammosphex) yasumatsui Wolf and Móczár, 1972 in having lateral surface of propodeum without any long erect setae and by very short anterior side of 3r-m cell of fore wing (sometimes 3r-m cell petiolate) (Fig. 105), but differs by having apical spine of first protarsomere 0.5–0.6 × length of second protarsomere (0.7–0.8 × in A. (A.) yasumatsui ). Clypeus as in Fig. 63 . Metapostnotum as in Fig. 83 .

Description. FEMALE (hitherto unknown). Body length 5.8–8.5 mm. Fore wing length 4.3–6.0 mm. Head width 1.1 × its height. Ocelli small, POD/OOD 1.0–1.1. Ratio of genal median width to eye median width (lateral view) 0.5–0.7. Ratio of eye median width to half width of frons (frontal view) 0.6–0.7. Clypeus weakly longitudinally convex, anterior border weakly emarginate with broad smooth rim, which not narrowed medially ( Fig. 63 ). Flagellomere 1 length 3.4–3.8 × its width. Relation of scape, pedicel and first two flagellomeres 32–35: 13–14: 35–40: 30–35. Apical flagellomere acuminate. Mesosoma length dorsally 1.5–1.6 × its width. Pronotum median length 0.4–0.5 × its median width, posterior pronotal border obtuse-angulate. Metanotum median length 1.5–1.6 × metapostnotum median length. Metapostnotum shiny with transverse striae. Metapostnotum posterior border with or without small smooth median triangle ( Fig. 83 ). Spines of tarsal comb short, protarsomere 1 with three spines of tarsal comb, tarsomere 2 with two spines, tarsomere 3 with one spine, tarsomeres 4 and 5 without spines; apical spine of protarsomere 1 0.5–0.6 × length of protarsomere 2; apical spine of tarsomere 2 0.6–0.8 × length of tarsomere 3. Wings slightly infuscated with weakly darker apical portion, venation of fore wing as in Fig. 105.

Gena, propleura with long erect scattered gray setae. Fore coxa, S2–S6, T6 with more sparse long erect brown setae. Clypeus, vertex, pronotum posteriorly, scutum with long erect sparse brown setae. Mandible with 2–3 long curved and a few short brown or pale brown setae. Frons and propodeum lacking setae. Lower part of face, sides of mesosoma, propodeum, coxae posteriorly with iridescent mainly silver-gray pubescence. Mesosoma dorsally, coxae anteriorly, legs and most part of metasoma with brownish micropubescence. Frons usually without pubescence or with sparse brownish micropubescence. Body regularly micropunctate; frons puncticulate. Body and legs black. Mandible pale brown medially and dark brown apically; T1 (except basal portion), T2 and basal part of T3 ferruginous-red.
