Subgeneric characters (from: Evans 1951, with modification). Small wasps, 3.5 to 12 mm in length. Color black, some species with basal abdominal segments rufous. Body with variable amount of erect setae, but seldom as many as in the subgenus Arachnospila Kincaid, 1900; front and propodeum at most moderately setose. Mandibles bidentate in male, tridentate in female. Antennal segment 3 [flagellomere 1] of male over twice as long as thick, and as long as segment 4 [flagellomere 2]. Posterior margin of pronotum distinctly angulate. Postnotum [metapostnotum] of moderate length, at least half length of metanotum. Front tarsus of female with comb of short to fairly long spines, basitarsus always with three comb-spines [seldom with four comb-spines]. Last tarsomere of front tarsus of male strongly asymmetrical, with lobe on inner margin that reaches its widest at about middle of tarsomere, outer claw of this tarsomere bifid, the inner claw bifid with inner ray short and rounded. Pulvillar comb fairly well developed, of about 12 setulae for female, about 8 for male. Fore wing with basal [M] vein arising at or slightly before transverse median [cu-a] vein. Stigma very short; marginal [radial] cell short, not more than 2.5 × as long as high, at least 1.3 × its own length from the tip of the wing. Second and third submarginal [radio-medial] cells rather small, rarely wider than high, often higher than wide, much narrowed above [Figs 95–125]. Subgenital plate of male variously modified, never with large lateral expansions at the base or with palpus-like processes [Figs 1–37]. Genitalia [Figs 38–56] with double basal hooklets: parameres [gonostyli] long and more or less setose; digiti [volsella] of rather uniform pattern throughout group, expanded and curved apically, disc usually with area of feeble longitudinal striolations toward apex. Parapenials rather short, always shorter than aedoeagus; aedoeagus [penial valves] bearing somewhere along its margins number of small, pigmented, tooth-like projections, clearly visible under high magnification.
Biology. Members of this subgenus occur in a variety of habitats from open steppe areas to any type of forest, where they may be found close to the ground in sunny spots. A few data are known about the habitats of species from the Russian Far East and East Siberia. Usually Arachnospila (Ammosphex) kuwayamai (Ishikawa) and other species of the A. (A.) abnormis- group inhabit sandy shores of rivers and lakes.
The prey consists of spiders Lycosidae, Clubionidae, Gnaphosidae, Pisauridae, Salticidae, Thomisidae, Segestriidae (Evans 1951, Krombein 1979, WiŠniowski 2009).
Distribution. Holarctic Region; represented in Europe by 18 species, in Russia by 25 species, of which 19 species inhabit the Russian Far East and East Siberia and are included in this paper. Eleven species of this subgenus occur in North America (Krombein 1979).
