Diagnosis of male. The male of this species is very similar to that of Arachnospila (Ammosphex) dschingis Wolf and Móczár, 1972, but is easily distinguished by having the gonostyli approximately equal to the parapenial lobe in length (longer than the parapenial lobe in A. (A.) dschingis), by the gonostyli with short erect scattered setae apically (with long erect dense setae in A. (A.) dschingis), by the volsella rounded apically (acuminate in A. (A.) dschingis) (Fig. 53 vs. 54). The differences from other males of the subgenus Ammosphex, which are distributed in the Russian Far East and East Siberia, are given in the key below.
Description. MALE. Body length 5.4–6.0 mm (holotype 6.0 mm). Fore wing length 4.1–4.8 mm (holotype 4.2 mm). Head width 1.2–1.3 × its height. Ocelli small, POD/OOD 0.70–0.86. Ratio of genal median width to eye median width (lateral view) 0.45–0.57. Clypeus weakly convex, anterior border weakly and arcuately emarginate. Labrum flat, anterior border weakly emarginate medially. Flagellomere 1 length 1.22–1.38 × its width. Relation of scape, pedicel and two first flagellomeres 25–30: 10–11: 17–19: 19–22. Mesosoma length dorsally 1.37–1.60 × its maximum width. Pronotum median length 0.35–0.47 × its median width, posterior pronotal border indistinctly angulate. Metanotum median length 2.20–2.75 × metapostnotum median length. Metapostnotum shiny with transverse striae, its posterior border with smooth shiny triangle medially. Propodeum with median longitudinal furrow dorsally; its median length 0.7 × its maximum width (dorsal view). Fore wing slightly infuscated with darker apical part, venation as in Fig. 98, 3r-m cell usually nearly trapeziform, sometimes triangular. Hypopygium gradually narrowed to the apex, with high longitudinal median carina and short dense setae ventro-laterally (Figs 32, 33). Genitalia as in Fig. 53.
Propleura, genae, and labrum latero-apically with long erect setae. Mandible with 2–3 long strong and a few short soft erect setae. Inner eye orbit with long erect sparse setae. Other body parts without setae. Lateral side of mesosoma and propodeum, and hind side of mid and hind coxae with dense silver to gray pubescence. Head, pronotum, mesoscutum, scutellum, metanotum, fore coxae, and mid and hind coxae anteriorly with brownish pubescence. Metasoma with regular sparse gray pubescence. Body regularly micropunctate. Body and legs black. Mandible brownish apically, T1 and S1 (except basal portion), T2 and S2 (except apical portion), and sometimes T3 basally ferruginous-red.
FEMALE. Unknown.
Type material. Holotype, 3, RUSSIA: Primorskiy Terr., Spassk, 3–6.VII.1993 (S. Belokobylskij) [ZIN]. Paratypes, 2 3, RUSSIA: Primorskiy Terr., Lazovsky Reserve, Korpad, 17.VII.2008 (V. Loktionov) [IBSS].
Distribution. Russia (Primorskiy Terr.).
Etymology. Named after Sergey A. Belokobylskij (Zoological Institute, St. Petersburg, Russia), a specialist in Braconidae, excellent collector of Hymenoptera, for his contributions to the taxonomy of Pompilidae.
Biology. Inhabits glades in broad-leaved forest.
