Diagnosis.

Maximum width of hypoclypeal depression 0.6-0.7 × minimum width of face (Fig. 822 ); OOL twice as long as diameter of posterior ocellus and coarsely rugose; clypeus rather short, rather flat, weakly protruding anteriorly and its ventral margin thick (Fig. 824 ); mesoscutum coarsely and remotely punctate, with interspaces smooth and wider than punctures; precoxal sulcus area coarsely and densely punctate; vein 1-CU1 of fore wing approx. 0.8 × as long as vein 2-CU1 and as long as vein m-cu (Fig. 815 ); membrane near veins M+CU1 and 1-CU1 of fore wing sparsely setose; tarsal claws rather robust and with some fine dark brown spiny bristles subbasally (Fig. 825 ); head brownish yellow; vein 1-M of fore wing brown; apical half of hind tibia dark brown; metasoma of ♀ yellowish, but anterior 0.6 of first tergite black; wing membrane subhyaline.

Description.

Holotype of A. venustulus , ♀, length of fore wing 6.7 mm, of body 8.6 mm.

Head. Antenna incomplete, with eight segments remaining; frons rugose and shiny; OOL twice diameter of posterior ocellus, mainly rugose and shiny; stemmaticum densely punctate; vertex remotely punctate and shiny; clypeus punctate and slightly convex; ventral margin of clypeus thick and anterior part weakly protruding (Fig. 824 ); width of hypoclypeal depression 0.6 × minimum width of face (Fig. 822 ); length of eye 1.3 × temple in dorsal view (Fig. 823 ); vertex behind stemmaticum convex and remotely punctate; clypeus near lower level of eyes; length of malar space 0.4 × length of eye in lateral view and temple as wide as eye.

Mesosoma. Mesoscutum coarsely and remotely punctate, with interspaces smooth and wider than punctures; precoxal area coarsely and densely punctate, remainder of mesopleuron remotely punctate and antero-dorsally rugose; metapleuron densely and coarsely punctate; metanotum with coarse medio-longitudinal carina anteriorly; scutellum punctate; propodeum convex and coarsely rugose, its medio-longitudinal carina present only on anterior third of propodeum.

Wings. Fore wing: r 0.4 × 3-SR (Fig. 815 ); 1-CU1 slightly oblique, 0.2 × 2-CU1; r-m 0.6 × 3-SR; 2nd submarginal cell medium-sized (Fig. 815 ); cu-a inclivous, straight; 1-M nearly straight posteriorly; 1-SR wide; surroundings of M+CU1, 1-M and 1-CU1 largely glabrous. Hind wing: marginal cell linearly widened, its apical width twice width at level of hamuli (Fig. 816 ); 2-SC+R short and vertical; m-cu absent; M+CU:1-M = 12:11; 1r-m 0.7 × 1-M.

Legs. Tarsal claws rather robust and with some fine dark brown spiny bristles subbasally (Fig. 825 ); hind coxa largely densely punctate; hind trochantellus rather robust; length of hind femur and basitarsus 4.7 and 6.5 × their width, respectively; length of inner hind spur 0.4 × hind basitarsus.

Metasoma. First tergite evenly convex, as long as wide apically; 1st and 2nd tergites with medio-longitudinal carina and coarsely rugose-reticulate; medio-basal area of 2nd tergite triangular and rather distinct (Fig. 819 ); 2nd suture deep and narrow; basal half of 3rd tergite punctate-rugose, remainder of metasoma superficially micro-sculptured; 4th and apical half of 3rd tergite without sharp lateral crease; ovipositor sheath wide, with long setae and apically truncate (Fig. 814 ).

Colour. Black; antenna (except scapus and pedicellus), palpi, tegulae, fore and middle telotarsi, veins, and pterostigma dark brown; coxae, trochanters and trochantelli, apical third of hind femur (ventrally extended to its apical two-thirds), hind tibia (except pale yellowish basal ring), fore and middle femora apically, and hind tarsus black; remainder of legs yellowish brown; wing membrane subhyaline.

Variation. No specimens with intact antennae examined; 2nd tergite coarsely rugose-reticulate or coarsely longitudinally rugose. Male is very similar and with apical tergites type 3, setae quite dense, glabrous stripe narrow, and fringe very weak.

Distribution.

Kazakhstan, Kyrgyzstan.

Notes.

This Central Asian species bears a superficial resemblance to A. miniatus and A. aestuosus . It is included in this revision, because it has been reported twice from Turkey ( Aydogdu and Beyarslan 2005, 2006).
