Material examined.

Mongolia. 1 ♂, Bayankhongor 130 km S, 1240 m, 45.03'N, 100.59'E, 06.07.2004, J. Halada ( OLML) .

Description.

Male. Body length 4.0–5.0 mm, lateral view Fig. 15 View Figures 1–16 . Head and mesosoma black. Antenna reddish-brown, mandible reddish with brown tip. Antennomeres I – III with short white setae. Mandible basally with deep transverse sulcus, medially with tuft of pale setae. Malar space about 3 × as long as diameter of anterior ocellus. Middle clypeal lobe medially with short triangular tooth in the middle and small lateral teeth, separating middle lobe from lateral lobes (Fig. 10 View Figures 1–16 ). Clypeus indistinctly punctate, lateral lobes without distinct striae, finely punctate. Face finely punctate, with long white setae; frons, vertex and occiput smooth and shiny (Fig. 16 View Figures 1–16 ). Head behind eyes well developed, about as long as eye length on vertex. Mesoscutum, mesoscutellum and mesopleuron smooth and shiny. Mesoscutum anteriorly and mesopleuron with scattered pale setae. Propodeal dorsum very finely micro-reticulated. Lateral surface of propodeum strongly coriaceous, declivity with strong punctures, both with long white setae. Metasoma dark brown to black, pygidium reddish. Tergum I and sterna with white setae. Femora dark brown with reddish apex and short white setae, longest ventral setae of hind femur distinctly shorter than half maximal femur diameter. Tibiae and tarsi reddish. Wings hyaline. Tegula brown; basal sclerites and base of forewing veins pale yellowish, other veins brown; pterostigma brown, basal quarter pale yellow. Anterior margin of marginal cell about 0.8 × as long as apical height (Fig. 2 View Figures 1–16 ).

Female (from Kazenas 1996, 2000). Body length 4 mm. Head and mesosoma black, pronotal lobe brown; metasoma black, proximal terga sometimes brownish, pygidium reddish. Femora dark brown to black with reddish apex, tibiae and tarsi reddish. Mandible reddish-yellow, tip dark brown. Antenna brown, apically reddish. Clypeus reddish-brown, middle clypeal lobe weakly convex, separated from lateral lobes by short teeth directed obliquely forward (Fig. 11 View Figures 1–16 ). Malar space about as long as diameter of anterior ocellus. Frons strongly and evenly curved, smooth and shiny; nearly without punctures and microsculpture, medially with deep longitudinal furrow. Distance between antennal insertions about as wide as insertion diameter, about 2.5 × as wide as distance between insertion and eye. Mesoscutum glabrous, smooth and shiny, with very scattered fine punctures. Mesoscutellum with deep longitudinal furrow. Mesopleuron smooth and shiny, with some pale setae. Propodeal dorsum finely reticulated, posterior surface smooth. Lateral propodeal surface smooth and shiny, with sparse white setation. Tegula reddish-brown, posteriorly hyaline. Wing veins brown or reddish-brown, basally whitish-yellow. Pterostigma brown with whitish-yellow base as well as adjacent part of costa. Marginal cell very short, apically rounded, anterior margin less than half as long as posterior height (Fig. 3 View Figures 1–16 ). First recurrent vein leads to submarginal cell I.

Distribution

(Fig. 35 View Figure 35 ). Turkmenistan ( holotype), Kazakhstan ( paratypes, Kazenas 1972, 1996, 2002), Mongolia ( Tsuneki 1971), Russia: Astrakhan prov. ( Mokrousov et al. 2016) (Fig. 35 View Figure 35 ). The isolated record (a single male) from Israel ( Mokrousov et al. 2016) requires confirmation and is not included in the distribution map.
