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.

Description. Male. Unknown.

Female. Body length 18 mm. Head ( Fig 19 View Figure ). Clypeus slightly elongated; apical margin slightly undulate, reddish-brown. Clypeal disk distinctly concave anteriorly, sparsely punctate (punctures 2–3 diameters apart), shiny. Clypeus with fine sparse appressed silvery setae (except glabrous on medial concavity and along apical margin). 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 View Figure ). Pronotum glabrous, shiny, slightly microsculptured, with scattered inconspicuous punctures (punctures 3 and more diameters apart). Pronotal collar rounded dorsally. 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. Hindcoxa with dense appressed silvery setae dorsally. Claws without teeth. Metasoma. Petiole red with black stripe ventrally, T1 red with black stripe dorsally, T2-T3 and S2-S3 red, T4-T6 and S4-S6 black with no blue reflexes; metasoma slightly pruinose.
