Molecular data.

None.

Biology.

Unknown. Probably univoltine as all known adults were collected in the period June to August, but there is no indication of its means of overwintering.

Diagnosis.

Maximum width of hypoclypeal depression approx. 0.7 × minimum width of face (Fig. 837 ); OOL of ♀ finely remotely punctate and 0.8-1.0 × diameter of posterior ocellus; ventral margin of clypeus thick apically and not protruding in lateral view (Fig. 839 ); lobes of mesoscutum densely finely punctate, with interspaces shiny; precoxal area densely punctate and with some rugae medially; vein cu-a of fore wing oblique, parallel with vein 3-CU1; surroundings of veins M+CU1 and 1-+2-CU1 largely setose; vein r of fore wing 0.4-0.5 × vein 3-SR (Fig. 830 ); vein 1-CU1 of fore wing 0.3-0.6 × vein 2-CU1 (Fig. 830 ); hind tarsal claws with rather conspicuous pale brown pecten (Fig. 840 ); 1st tergite gradually narrowed basally (Fig. 833 ); 2nd tergite 0.7 × as long as wide basally and black; 3rd tergite densely punctulate basally, and sparsely so apically; head black; vein 1-M of fore wing brown; wing membrane subhyaline.

This new species is similar to A. cruentus (Nees), but it differs by having the surroundings of veins M+CU1 and 1-+2-CU1 partly setose (Fig. 828 ; largely glabrous in A. cruentus ), vein M+CU1 of fore wing with bend near its distal fifth (Fig. 828 ; straight or slightly curved), vein cu-a of fore wing oblique, parallel with vein 3-CU1 (vertical or nearly so, rarely oblique), vein r of fore wing 0.4-0.5 × vein 3-SR (0.3-0.4 ×), vein 1-CU1 of fore wing 0.3-0.6 × vein 2-CU1 (0.8-1.1 ×, rarely less), OOL of ♀ 0.8-1.0 × diameter of posterior ocellus (0.5-0.8 ×, rarely longer), length of eye 1.1-1.6 × temple in dorsal view (1.5-1.9 ×), ovipositor sheath comparatively slender and area between ocelli and eyes moderately punctate (coarsely punctate). Also very similar to A. diversus ( Szépligeti), it differs from the latter by having vein 1-CU1 of fore wing distinctly shorter than vein m-cu, hind femur approx. 4 × as long as wide, vein cu-a inclivous (parallel with vein 3-CU1; vertical and vein 3-CU1 diverging posteriorly in A. diversus ), 5th-10th antennal segments of ♀ as long as wide (shorter than wide), vertex and OOL remotely punctate (densely punctate) and ovipositor sheath slender (robust).

Description.

Holotype, ♀, length of fore wing 7.0 mm, of body 9.0 mm.

Head. Antennal segments of ♀ 59, length of antenna 1.1 × fore wing, its subapical segments moderately slender; frons largely smooth; OOL equal to diameter of posterior ocellus, finely remotely punctate and shiny; vertex distinctly punctate and shiny; clypeus punctate-rugose, wide and short; ventral margin of clypeus thick and not protruding forwards (Fig. 839 ); width of hypoclypeal depression 0.7 × minimum width of face (Fig. 837 ); length of eye 1.1 × temple in dorsal view (Fig. 838 ); vertex behind stemmaticum densely punctate; clypeus near lower level of eyes; length of malar space 0.25 × length of eye in lateral view.

Mesosoma. Mesoscutal lobes largely densely and finely punctate, shiny; precoxal area of mesopleuron densely punctate, medially with few rugae; surroundings of precoxal area densely punctate; scutellum sparsely and finely punctate, rather flat, shiny and laterally rugose-punctate; propodeum evenly convex and coarsely rugose, medio-longitudinal carina complete but irregular posteriorly, and no protruding carinae laterally.

Wings. Fore wing: r 0.4 × 3-SR (Fig. 830 ); 1-CU1 horizontal, 0.5 × 2-CU1 and 0.7 × m-cu; r-m 0.6 × 3-SR; 2nd submarginal cell medium-sized (Fig. 830 ); cu-a inclivous, straight; 1-M slightly curved posteriorly; vein M+CU1 of fore wing with distinct bend near its distal fifth (Fig. 828 ); 1-SR widened; surroundings of M+CU1, 1-M and 1-CU1 largely setose. Hind wing: marginal cell gradually widened, its apical width 2.1 × width at level of hamuli (Fig. 830 ); 2-SC+R subquadrate; short m-cu weakly developed; M+CU:1-M = 7:4; 1r-m 0.9 × 1-M.

Legs. Tarsal claws with rather conspicuous pale brownish pecten (Fig. 840 ); hind coxa largely densely punctulate; hind trochantellus robust; length of hind femur and basitarsus 4.0 and 5.0 × their width, respectively; length of inner hind spur 0.55 × hind basitarsus.

Metasoma. First tergite rather flattened, as long as wide apically and distinctly narrowed basally (Fig. 833 ); 1st and 2nd tergites with medio-longitudinal carina and coarsely longitudinally rugose; medio-basal area of 2nd tergite wide triangular and short (Fig. 833 ); 2nd tergite 0.7 × as long as its basal width; 2nd suture deep and finely reticulate; basally 3rd tergite densely punctulate and apically (as remainder of metasoma) sparsely punctulate; 4th and apical half of 3rd tergite without sharp lateral crease; ovipositor sheath slender, with medium-sized setae and apically rounded (Fig. 829 ).

Colour. Black (including fore coxa anteriorly and basally); apex of hind tibia, telotarsi, hind tarsus, palpi, pterostigma and veins, dark brown; hind tibia (except apex) brownish yellow; clypeus narrowly ventrally, remainder of legs, pronotum (except ventrally), mesopleuron dorsally, mesoscutum, scutellum, and metanotum, orange-brown; tegulae pale brownish yellow; wing membrane subhyaline.

Variation. Antennal segments of ♀ 58(1), 59(1), 60(1), of ♂ 62(1); vein r of fore wing 0.4-0.5 × vein 3-SR; vein 1-CU1 of fore wing 0.3-0.6 × vein 2-CU1; OOL of ♀ 0.8-1.0 × diameter of posterior ocellus; length of eye 1.1-1.6 × temple in dorsal view; clypeus ventrally orange brown or black; mesopleuron dorsally or largely orange brown; basal half of third tergite rugose, punctate-rugose or punctulate; entire 1st tergite orange brown, posterior half of 1st tergite brownish and rest of tergite blackish (as base of middle coxa) or entirely black. Male is very similar, apical tergites type 1 and no fringe observed.

Distribution.

Turkey (Asian part: 1100-1800 m).
