Figures 1–6 .

Diagnosis. The male of A. antoninae closely resembles A. terminata turkestana Kohl, 1906 ( Figs 7–9 ) in having the glabrous propodeal enclosure, in the poorly represented appressed silvery setae on the body, and in having the pronotal collar and scutum finely transversely striate, but it is easily differentiated by the characteristically shaped penis valve ( Figs 5–6 , 9 ), and in having the clypeus with well-defined lateral angles (lateral angles absent in A. terminata turkestana ) ( Figs 3 , 8 ). The female is unknown.

Description. Male. Body length 15 mm. Head. Clypeus elongate, apical margin moderately concave with well-defined lateral angle ( Fig. 3 ). Clypeus, subantennal sclerite, and paraocular area with dense appressed silvery setae. Head with black erect setae. Vertex, occiput, and gena microsculptured, punctate; punctures 1–4 diameters apart. Mandible and palpi black. Mesosoma . Pronotum shiny, slightly prominent ( Fig. 2 ), finely transversely striate, sparsely punctate. Scutum slightly shiny, finely transversely striate anteriorly, finely obliquely striate posteriorly. Scutellum longitudinally rugose. Mesopleuron and metapleuron dull, microsculptured, slightly rugose, with inconspicuous sparse appressed silvery setae (setae denser ventrally). Propodeal enclosure glabrous, dull, obliquely striate. Propodeum shiny, rugose, with inconspicuous spot of appressed silvery setae posteriorly. Tegula black and translucent posteriorly. Erect setae black. Wings hyaline; veins dark brown; costal vein black. Legs black with sparse appressed silvery setae. Claws without teeth. Metasoma. T1-T3 and S1-S3 (excluding petiole) red; petiole black; T4-T7 and S4-S7 black with blue reflexes. Penis valve characteristically shaped: massive, broad, and semicircularly convex dorsally ( Figs 5–6 ).
