Arachnospila ( Ammosphex ) kurentzovi Lelej, 1995 (Figs 7, 8, 42, 62, 82, 104) Arachnospila ( Ammosphex ) kurentzovi Lelej, 1995: 245, 3 (holotype, 3, Primorskiy Terr., Zanadvorovka, 23.VI. 1987 (Lelej) [IBSS], examined); Loktionov 2011: 83. 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 roof-like hypopygium without any row of setae or bristles baso-laterally (Figs 7, 8 vs . 1 –6, 9– 12). The male of this species differs from very similar A. ( A. ) kuwayamai (Ishikawa, 1966) by having hypopygium acuminate apically (rounded apically in A. ( A. ) kuwayamai ) (Figs 7, 8 vs . 9, 10). Genitalia as in Fig. 42. Diagnosis of female. The female of this species is similar to other females which have narrow eye and wide frons, but differs by having apical flagellomere length almost 3 × its width (2 × in Arachnospila ( Ammosphex ) orientausa sp. nov. ), by less hirsute propodeum, which has ~ 20 long erect setae (~ 50 long erect setae in A. ( A. ) rasnitsyni sp.nov. ), and by shiny anterior rim of clypeus, which is indistinctly set off from other part of clypeus (distinctly set off in other females) (Fig. 62 vs . 57, 59, 60, 63–66, 69– 75). Metapostnotum as in Fig. 82. Venation of fore wing as in Fig. 104. Description. FEMALE (hitherto unknown). Body length 7.9–9.7 mm. Fore wing length 6.0–7.0 mm. Head width 1.1–1.2 × its height. Ocelli small, POD/OOD 0.9 –1.0. Ratio of genal median width to eye median width (lateral view) 0.5. Ratio of eye median width to half width of frons (frontal view) 0.6–0.7. Clypeus longitudinally convex, with straight or weakly emarginate anterior border and narrow smooth rim (Fig. 62). Flagellomere 1 length 3.8 × its width. Relation of scape, pedicel and first two flagellomeres 32–40: 15: 46–57: 39–51. Apical flagellomere acuminate. Mesosoma length dorsally 1.4–1.5 × its width. Pronotum median length 0.4 × its median width, posterior pronotal border obtuse-angulate. Metanotum median length 1.8 × metapostnotum median length. Metapostnotum as in Fig. 82. 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 0.4–0.5 × length of protarsomere 2; apical spine of tarsomere 2 0.5–0.7 × length of tarsomere 3. Wings infuscated with darker apical portion, venation of fore wing as in Fig. 104. Frons with 1 long and 2–3 short erect dark brown setae. Fore coxa anteriorly, T 6, S 2 –S 6 apically with long erect dark brown scattered setae. Gena and propleura with denser long erect soft pale brown setae. Pronotum dorsally, mesoscutum, scutellum, and metanotum with a few erect setae. Clypeus with six long erect dark brown strong setae. Each side of propodeum with 3–4 long erect setae. Head, mesosoma, propodeum, legs (except coxae posteriorly) with gray-brownish micropubescence. Coxae posteriorly with silver pubescence. Metasoma with gray micropubescence. Body regularly micropunctate; frons matt puncticulate. Body and legs black. Mandible pale brown medially, dark brown basally and apically; T 1 (except basal portion) and T 2 (except apical portion) ferruginous-red. Type material. Paratypes .
