Vertex narrow, nearly as wide as ocellar diameter, densely punctate; surface above compound eyes with dense punctures, interval area is not visible; OOD:POD:OCD = 4:3:2; FL1 = FL2+FL3, FL2 = FL3; inner margin of eyes subparallel; facial fovea in upper part occupying 1/2 of distance between compound eye and lateral ocellus, not exceeding the lower level of antennal socket, FVL = 1 mm, FVW = 0.25 mm, facial quadrangle quadrate (nearly 1:1). Face above antennal fossae reticulate without longitudinal rugulae, interrugal space smooth and shiny. Clypeus slightly convex, with slanting PP (Pd = 55 µm), IS<0.1, without clear impunctate median line, shiny and smooth; CPL = 0.8 mm. Process of labrum moderate, emarginated, shiny; lower paraocular area with very dense irregular, large PP (Pd = 55 µm), IS<0.1. Malar space linear. GW<EW (2.5:3), surface smooth and shiny with very dense and ununiform, PP (Pd = 15 µm), IS<0.1 near eye.

Propodeal enclosure medium size, not well indicated by boundary line, strongly rugose with carina, interrugal surface smooth and shiny, dorsal area similar but with weaker rugose. Mesepisternum with dense PP, anterior part reticulate, posterior part with coarse PP, surface smooth and shiny; anterior part of tegula smooth, with PP.

Metasoma: Metasomal terga with dense, small PP (Pd = 20 µm), IS<0.1, smooth and shiny; posterior depression of T2–4 laterally distinct, with smaller PP; pygidial plate V-shaped, without internal raised area; S2–5 smooth and shiny with fine and deep PP.

Male [Florya region, Istanbul, Turkey, 21.v.1964 (W. Grünwaldt)]: BL = 6.5 mm, WL = 5 mm.

Color. Flagellum reddish brown beneath; mandible, wing membrane, veins and pterostigma as in female; posterior part of tegula translucent, reddish brown, anterior part dark brown. Rest of body black.

Pubescence. Hairs on head, thorax and clypeus as in female; those on vertex dull whitish, short, 300 µm; those on genal area yellowish; hairs on mesoscutum short (100–250 µm), on scutellum longer (500 µm); those on mesepisternum with the same color and size. Hairs on metasomal terga as in female, T3–5 with complete yellowish hair bands, S2–5 as in female.

Structure. Head: HL/HW = 0.9, HW:MsW:MtW and Vertex as in female; OOD:POD:OCD = 2:2:1; FL1<FL2+FL3, FL2<FL3; inner margins of eyes subparallel; facial quadrangle as in female. Face above antennal fossae reticulate without longitudinal rugulae, interrugal space smooth and shiny. Clypeus as in female; CPL = 0.5 mm. Process of labrum quadrangle, apically rounded; lower paraocular area with very dense, large punctures (Pd = 60 µm, IS<0.1). Malar space linear. Genal area narrower than eye (3:4), surface with very dense PP (Pd = 35 µm), IS<0.1 near eye. Mandibles not crossing at rest.

Mesosoma: Pronotum without humeral angle, weakly tessellate with scattered PP, dorsally with dense PP at middle, laterally with weak wrinkles. Mesoscutum, scutellum, propodeal enclosure, mesepisternum and tegula as in female.

Metasoma: Metasomal terga with dense small PP, smooth and shiny; posterior depressions of T2–5 not well indicated; genitalia and S8 as in Fig. 9 E,F; S2–5 smooth and shiny with very shallow PP.

Remarks. This species is similar to A. miegiella Dours , but is separated by the emarginated process of labrum, the pronotum without dorsolateral suture and the thorax without tawny hairs.

Variation. The first generation is characterized by having longer and thinner hairs and darker antennae than the second generation.

Sculpture of enclosure area shows wide rande of variability (rectangular fovea to irregular rugose). Also, punctuation of terga, impunctate area of marginal zones of terga 2–4 and length of fovea on T2 show variation.
