Diagnosis of male. The male of new species is most similar to that of Palaearctic A. scriptus, but differs by having labrum with two weak tubercles anteriorly and longitudinal median carina (with two strong teeth anteriorly and lacking longitudinal median carina in A. scriptus), by having flagellomere 1 length 0.8 × flagellomeres 2–4 combined together (equal flagellomeres 2–4 combined together in A. scriptus, Fig. 17 vs. Fig. 16), by having gonostyle with a few short setae (with abundant long setae in A. scriptus, Fig. 5 vs. Figs 11, 14), by having S7 narrow, with long lateral lobes and narrow apex (S7 wide, with short lateral lobe and wide apex in A. scriptus, Fig. 6 vs. Figs 12, 15), by having S8 wider than long, with strongly chitinized projecting rounded apex (S8 longer than wide, with weakly chitinized emarginated apex in A. scriptus, Fig. 7 vs. Fig. 13).
Diagnosis of female. The female of new species is most similar to that of Palaearctic A. scriptus, but differs by having labrum lacking tubercles anteriorly and with longitudinal median carina (with two denticles anteriorly and lacking longitudinal median carina in A. scriptus), by having mesoscutum shiny, with sparse irregular foveae and small punctures, much denser laterally; disc with rare punctures (mesoscutum more or less matt, with uniform foveae and small punctures, interspaces usually no more than their diameter in A. scriptus, Fig. 23 vs. Fig. 25); by having metasomal terga shiny, densely foveolate, with interspaces from 0.5 to 3.0 their diameter, apically densely punctured (metasomal terga matt, densely punctured, interspaces 0.25–0.33 their diameter in A. scriptus, Fig. 23 vs. Fig. 25); by having T1–T4 posteriorly with interrupted band of white plumose setae (T1–T5 posteriorly with interrupted band of white plumose setae in A. scriptus, Fig. 23 vs. Fig. 25).

Malar space exceedingly short, base of mandible almost touching compound eye. Labrum with two weak tubercles anteriorly and longitudinal median carina, covered with reddish setae. Clypeus weakly convex with smooth and shiny anterior border. Integument black except part of mandible dark reddish-brown. Supraclypeal area with median longitudinal carina. Paraocular and supraclypeal areas densely covered with long, greyish-white, erect setae. Vertex densely foveolate with smooth patch laterad of ocellus. Antenna 13-segmented. Apical flagellomere widened (Fig. 18). Flagellomere 1 length 0.8 × flagellomeres 2–4 combined together (Fig. 17). Flagellomeres black to brown, reddish-brown beneath. Mesosoma. Integument black. Mesoscutal disc between punctures smooth and shiny; densely punctate, sparser on disc. Scutellum medially longitudinally invaginated. Axilla not swallen. Metanotum densely punctate. Metapostnotum medially finely punctate, lacking setae. Mesoscutum, scutellum, metanotum, mesepisternum, and propodeum covered with long, greyish-white erect setae. Wings. Slightly yellowish-brown; wing venation dark brown. Legs. Integument black to dark reddish-brown. Hind tibia dorsally with white plumose setae; mid and hind basitarsus inside with reddish brush. Metasoma. Integument black except depressed apical tergal margins reddish translucent. Terga with irregular foveae, interspaces from 0.5 (T1–T2) to 3–5 (T3–T6) their diameter. Т1–Т6 posteriorly with band of white setae, interrupted medially (Figs 28, 29). Metasoma covered with erect black setae, longer and denser on sterna. Terminalia. Genitalia and S7–S8 as illustrated (Figs 5–7).
Female. Body length 11.0–12.0 mm. Head. Head wider than long; width 3.7 mm, length 3.3 mm. Mandible simple and pointed apically. Malar space exceedingly short, base of mandible almost touching compound eye. Labrum lacking tubercles anteriorly, with longitudinal median carina, covered with long erect black setae. Clypeus weakly convex, with smooth and shiny anterior border. Integument black except part of mandible dark reddishbrown. Supraclypeal area with longitudinal carina. Paraocular and supraclypeal areas densely covered with long, greyish-white, erect hairs. Vertex densely foveolate, with smooth patch postero-laterally of ocellus. Antenna 12- segmented. Flagellomeres black, weakly reddish-brown beneath. Mesosoma. Integument black. Mesoscutum with sparse irregular foveae and small punctures, much denser laterally; disc shiny, with rare punctures. Scutellum medially longitudinally invaginated. Axilla swallen. Metanotum densely punctate. Metapostnotum medially finely punctate, lacking setae. Scutellum, metanotum, mesepisternum and propodeum covered with long, black erect setae. Wings. Slightly yellowish-brown; wing venation dark brown. Legs. Integument black to dark reddish-brown. Mid tibia dorso-basally and hind tibia dorsally with white plumose setae. Mid and hind basitarsus inside with black brush. Metasoma. Integument black except depressed apical tergal margins reddish translucent. Terga shiny, densely foveolate, with interspaces 0.5–3.0 diameter. T1–T4 with band of white setae, interrupted medially (Figs 22, 23). Metasoma covered with subappressed black setae. Apical sternal seta bands broad.

Etymology. The species is dedicated to Oktawiucz Wincenty Radoszkowski (1820–1895), who was an expert in many groups of bees and wasps and described the genus Ammobatoides.
Hosts. Probably Melitturga mongolica Alfken (Andrenidae: Panurginae) (in Buryatia the specimens of new species have been collected together with the specimens of Melitturga mongolica).
