Abdomen orange-yellow, with black and brown pattern. 1+2nd tergite at base and in central part shining black, yellowish-brown laterally; 3rd and 4th tergites with median longitudinal black spots (shining in basal 0.4–0.5 and dense light dust apically) and paired brownish-black lateral stripes in basal 0.3; the distances between spot and stripes of 4th abdominal tergite significantly less then diameter of median spot; 5th tergite with 3 shining black rounded spots in basal three-fourths; 6th tergite with shining black median spot; genitalia reddish-brown.

Body length: 5.0 mm.

Head: Frons at vertex 0.34×, at level of antennal base 0.33× of head width. Frontal vitta 2.5× widened backwards, 1.2× wide as one of parafrontalia. Flagellomere 2.5× as long as pedicel, arista widened in basal 0.8. Parafacialia at level of antennal base 0.20×, genae 0.12× of eye height. Palpi at apex widened. Ocellars short, hair-liked; vte absent; fr 9–10, midlong and strong; orb 1+4, slightly longer than fr; parafrontalia and parafacialia with microscopic light setae; genae with erect yellow hairs; only one pair of vi presents; 8–10 oral bristles black, others numerous and yellow ( Figures 1 and 2 ).

Mesosoma. Covered with short white hairs, bristles well developed; acr 4+5, prescutellar pair longest; dc 4+5; ia 1+3; pprn 2; npl 2; kepst 1+1; propleuron bare. Scutellum with 3 pairs of long and strong marg; d hair-liked. t 2 with one ad.

Wings. The petiolus of vein r 4+5 0.5 as long as r-m, vein r 4+5 with one basal seta, vein m right-angled, dm-cu s -liked curved ( Figure 3 ).

Legs. First tarsomere of hind tarsus widened and elongated, covered by several rows of numerous short spine-like setae, with ventral ctenidium constructed from short and thick hooked bristles ( Figure 4 ).

Metasoma. 1+2nd and 3rd tergites without marginal bristles, 4th tergite with a pair of medio-marginals, 5th and 6th tergites with rows of strong marginal bristles ( Figure 5 ). The median parts of hind margins of 4th and 5th tergites slightly stilted over the surface of next posterior tergite ( Figure 6 ). Genitalia small.

Etymology. The specific name is given in honor of one of the coauthors, the well-known Ukrainian entomologist Prof V Radchenko.

Type material. Holotype (male). Turkey, Antalya Province, Side city, sand waste plot, 36°46′05″N, 31°23′24″E, 10– 19.08.2011, Yu. G. Verves leg. Holotype in Institute for Evolutionary Ecology, National Academy of Sciences of Ukraine, Kyiv, Ukraine ( IEE-NASU) .

Comparison. This species is closely related to A. dispar Villeneuve, 1916 by construction of hind tarsi of male, head proportions, and presence of row of black oral setae, but differs by orange-yellow ground color of metasoma, right-angled vein m, and almost not stilted hind margins of 4th and 5th abdominal tergites.
