Type material.

Holotype of A. schewyrewi zaydamensis , ♀ (ZISP), "[Mongolia], Kerijsk Kr., Ruio Zaydam, Przewalski", “1910a”, [illegible handwritten label], " Rh. Schewyrewi Kokw. var. zaydamensis Kokw., No.1910a", "♀ Rhogas schewyrewi var. zaydamensis Kok., C. van Achterberg, 1992, holotype". Holotype of A. s. schewyrewi not found, according to the original description with same label data and with a larger part of the body blackish.

Additional material.

1 ♀ (BZL), "S. Russia, [Volgograd obl.], Elton Lake env., 20.v.2001, J. Miatleuski"; 1 ♂ (MTMA), "Mongolia, Gobi Altay aimak, Mongol els, 10 km SO von Somon Chechmort, 1600 m, Exp. Dr. Z. Kaszab, 1966", "Nr. 684, 13.vii.1966", " Rogas schewyrewi Kok., det. Papp J., 1977/ compared with ♀ det. Kokujev, Papp, 1983, 57".

Molecular data.

None.

Biology.

Unknown. A female collected in May and a male in July may suggest that it is plurivoltine (or, less probably, that the female overwinters as an adult).

Diagnosis.

Maximum width of hypoclypeal depression 0.6-0.7 × minimum width of face (Fig. 737 ); OOL of ♀ approx. as long as diameter of posterior ocellus and densely rugose (Fig. 738 ); head in anterior view rather robust (Fig. 737 ); clypeus distinctly protruding anteriorly in lateral view, thick apically and with long setae on medium-sized anterior part (Fig. 739 ); lobes of mesoscutum largely superficially punctate, interspaces finely granulate or smooth and with satin sheen; precoxal area densely rugose, but posterior third only finely punctate; vein 1-CU1 of fore wing 0.3 × vein 2-CU1 and 0.5 × vein m-cu (Fig. 730 ); hind tarsal claws long and slender, nearly straight and only brownish bristly setose (Fig. 740 ); tarsal segments (except telotarsus) with long apical spiny bristles (Fig. 728 ); basal half of hind tibia pale yellowish, contrasting with dark brown colour of basal half of hind femur.

Description.

Holotype, ♀, length of fore wing 5.8 mm, of body 7.5 mm.

Head. Antennal segments of ♀ 48, length of antenna 1.1 × fore wing, its subapical segments moderately slender (Fig. 742 ); frons largely with fine curved rugae; OOL equal to diameter of posterior ocellus, and densely rugose; vertex superficially rugose-punctate, rather shiny; clypeus convex and densely punctate; ventral margin of clypeus thick and protruding forwards (Fig. 740 ); width of hypoclypeal depression 0.6 × minimum width of face (Fig. 737 ); length of eye 1.3 × temple in dorsal view (Fig. 738 ); vertex behind stemmaticum finely rugose-punctate and with long setae; clypeus largely above lower level of eyes; length of malar space 0.3 × height of eye in lateral view.

Mesosoma. Mesoscutal lobes largely superficially punctate, interspaces finely granulate and with satin sheen; precoxal area of mesopleuron largely smooth medially, densely punctate anteriorly and posteriorly densely rugose, but posterior 0.3 only finely punctate; metapleuron spaced coarsely punctate; metanotum with fine and nearly complete median carina; scutellum sparsely punctate, shiny; propodeum rather convex and rather coarsely rugose, medio-longitudinal carina on anterior 0.4 of propodeum.

Wings. Fore wing: r curved and 0.4 × 3-SR (Fig. 730 ); 1-CU1 horizontal and slightly widened, 0.3 × 2-CU1; r-m 0.7 × 3-SR; 2nd submarginal cell medium-sized (Fig. 730 ); cu-a slightly inclivous, straight; 1-M slightly curved; 1-SR slender; surroundings of M+CU1, 1-M and 1-CU1 setose. Hind wing: basal third of marginal cell subparallel-sided and remainder linearly widened; 2-SC+R short and longitudinal; m-cu slightly indicated; M+CU:1-M = 10:7; 1r-m 0.6 × 1-M.

Legs. Tarsal claws long and slender, nearly straight and only brownish bristly setose (Fig. 740 ); tarsal segments (except telotarsus) with long apical spiny bristles (Figs 728 , 740 ); hind coxa largely punctate, but dorsally punctate-rugose; hind trochantellus rather robust; length of hind femur and basitarsus 4.7 and 6.6 × their width, respectively; length of inner hind spur 0.4 × hind basitarsus.

Metasoma. First tergite evenly convex and strongly widened posteriorly, 0.9 × longer than wide apically; 1st and 2nd tergites with weak medio-longitudinal carina (absent posteriorly) and finely longitudinally rugose, but 2nd tergite smooth medio-posteriorly; medio-basal area of 2nd tergite wide triangular and rather distinct (Fig. 734 ); 2nd suture deep and narrow; basal half of 3rd tergite aciculate, remainder of metasoma smooth and shiny; 2nd and 3rd tergites with sharp lateral crease; ovipositor sheath moderately widened, with medium-sized setae and apically truncate (Fig. 729 ).

Colour. Yellowish brown (including basal half of antenna); apical half of antenna, frons largely, stemmaticum, occiput dorso-laterally, pronotal side medially, axilla, mesopleuron (except antero-dorsally), mesosternum, metapleuron, propodeum, hind femur and apical third of hind tibia, 5th-7th tergites, last two posterior sternites, ovipositor sheath and pterostigma dark brown or blackish brown; veins brown; wing membrane subhyaline.

Variation. Length of 4th hind tarsal segment 1.8-2.0 × longer than wide; malar space and temple ventrally largely dark brown or yellowish brown. Antennal segments: ♀ 45(1); ♂ 54(1); according to original description ♀ type has 58 segments. Male has clypeus yellowish and contrasting with black face, apical tergites type 1, and no fringe observed.

Distribution.

*Iran, Mongolia, *Russia (European part).
