Diagnosis. The female of A. nemkovi has the metasomal apex with no blue reflexes, a glabrous propodeal enclosure, partly red legs, and no supra-antennal lamellate projection. The female of the new species is similar to A. sareptana Kohl, 1884 in having the glabrous propodeal enclosure, partly red mandible, tegula, and petiole, but differs in having the clypeus with only fine sparse appressed silvery setae not concealing the integument (clypeus with dense appressed silvery setae concealing integument in A. sareptana ), in having the mesosoma with appressed silvery setae only along the mesopleural suture, on the pronotal lobe and on the propodeum posterolaterally (mesopleuron entirely, pronotal lobe, pronotum dorsally, scutum and propodeum laterally with dense appressed silvery setae in A. sareptana ), and in having partly red legs (legs black in A. sareptana ). The male is unknown.

Subantennal sclerite and paraocular area with sparse, inconspicuous appressed silvery setae. Vertex and occiput slightly shiny, with scattered punctures. Erect setae pale. Supra-antennal lamellate projection absent. Mandible red in basal half. Palpi black. Mesosoma ( Figs 18, 20 ).

Pronotal lobe with lateral spot of dense appressed silvery setae. Scutum shiny, punctate anteriorly, slightly obliquely rugose and punctate posteriorly. Scutellum slightly shiny, punctate anteriorly, longitudinally rugose posteriorly. Mesopleuron rugose dorsoventrally and punctate, shiny, with stripe of appressed silvery setae along mesopleural suture. Metapleuron rugose, with sparse appressed silvery setae posteriorly. Propodeum punctatorugose with dense appressed silvery setae posteriorly. Propodeal enclosure glabrous. Erect setae sparse, pale. Tegula red. Wings slightly smoked; veins reddish-brown; costal vein and stigma dark-brown to black. Legs. Coxae black; trochanters, fore- and midfemur basally, midtarsus, and hindleg brownish; fore- and midfemur apically, fore- and midtibia, foretarsus and stripe on hindfemur dorsally red.
