Material. Holotype, 1♀ (ZJUH), “ [N. China:], Hebei, Mt. Xiaowutai, 1200 m, 22.viii.2005, Zhang Hongying, No. 200608550”; Paratype, 4 ♀ + 1♂ (ZJUH), id., but No. 200608698, 200608577, 200608587 and 200608558; 1♂ (ZJUH), id., but Shi Min, No. 200607920.
Diagnosis. Body brown; antenna incomplete, first flagellomere 1.8 × longer than second flagellomere (Fig. 2E); face smooth (Fig. 2I); frons flat and smooth (Fig. 2H); mandible with small fourth protuberance ventrally and no incision between second and third tooth (Fig. 2K); pronope small (Fig. 2H); mesopleuron smooth; episternal scrobe deep and narrow; metapleuron smooth (Fig. 2C); notauli only anteriorly impressed, absent posteriorly; mesoscutum smooth; medio-posterior depression elliptical; scutellar sulcus with three carinae; metanotum sculptured, and weakly protruding; surface of propodeum smooth, except for some short rugae near carina, medio-longitudinal carina complete and areola absent (Figs 2B, 2D); vein r of fore wing issued near base of pterostigma; SR1 of fore wing about 2.4 × 3-SR, m-cu of fore wing postfurcal (Fig. 2A); first tergite of metasoma 1.2 × its apical width, parallel-sided or nearly so; dorsal carinae converging, and dorsope medium-sized (Fig. 2D); length of setose part of ovipositor sheath 0.6 × as long as fore wing, and 1.7 × hind tibia (Fig. 2L).
Description. Holotype, ♀, length of body 3.4 mm, of fore wing 3.5 mm.
Head.Antenna incomplete, with 27 antennomeres remaining, length of first flagellomere 1.8 × as long as second flagellomere, length of first and second flagellomere 6.0 and 3.3 × their width, respectively (Fig. 2E); segments of labial palp rather slender; length of maxillary palp 1.2 × height of head; face smooth, with setae medially (Fig. 2I); length of eye in dorsal view 1.2 × temple; POL: diameter of ocellus: OOL= 11: 10: 21; frons flat and smooth (Fig. 2H); malar space without suture, and its length 0.1 × basal width of mandible (Fig. 2I); mandible with small fourth tooth ventrally and no incision between second and third tooth, and 1.4 × longer than its maximum width (Figs 2J–K).
Mesosoma. Length of mesosoma 1.5 × its height (Fig. 2C); pronope shallow (Fig. 2B); ventral side of pronotum smooth; mesopleuron smooth; episternal scrobe deep and narrow; metapleural flange smooth; metapleuron largely smooth (Fig. 2C); notauli crenulate, present at almost anterior half of mesoscutum; mesoscutum smooth and glabrous, but with some setae near imaginary notaulic courses; medio-posterior depression narrow and elliptical; scutellar sulcus deep and smooth, with three carinae; scutellum smooth; metanotum largely reticulate-rugose and weakly protruding; surface of propodeum smooth, except for some short rugae near carina, medio-longitudinal carina complete and areola absent.
Wing. Fore wing: r issued near base of pterostigma; r:3-SR:SR1 = 8:25:60; 2-SR:3-SR:r-m = 8:8:25; 1-CU1:2- CU1 = 1:12; m-cu distinctly postfurcal and parallel to 1-M; CU1b about as long as 3-CU1 (Fig. 2A).
Legs. Hind coxa smooth; tarsal claws rather slender; length of femur, tibia and basitarsus of hind leg 5.0, 11.3 and 10.0 × their width, respectively; length of hind tibia spurs 0.2–0.3 × hind basitarsus; hind tarsus normally setose (Fig. 2G).
Metasoma. Length of first tergite 1.2 × its apical width, surface largely smooth, with some striate posteriorly; first tergite parallel-sided or nearly so, its dorsal carinae converging and distinct in basal half of tergite; dorsope medium-sized, rather deep (Fig. 2D); length of setose part of ovipositor sheath 0.6 × as long as fore wing, and 1.7 × hind tibia (Fig. 2L).
Colour. Body brownish; palpi, legs and tegulae yellow; first and second flagellomere, annellus, mandible, basitarsus and anterior part of second metasomal tergite yellowish brown; wing membrane subhyaline (Fig. 1A).
Variation. Length of body of female 3.0– 3.6 mm, of fore wing of female 3.5–4.1 mm; first flagellomere 1.9–2.2 × as long as second flagellomere; first tergite of metasoma 1.0–1.3 × its apical width; length of setose part of ovipositor sheath 2.2–2.3 mm, 0.62–0.66 × as long as fore wing, and 1.7–1.8 × hind tibia.
Male. Similar to female except for the sexual characters.
Comparative diagnosis. The new species runs in the key to Palaearctic species by Belokobylskij (1997) to A. perdita (Haliday, 1838), but shares the weakly curved and comparatively short vein 3-SR of the fore wing with A. shelichovi Belokobylskij, 1997. The new species differs mainly by having the first tergite nearly parallel-sided (distinctly widened in both A. perdita and A. shelichovi). It differs from the latter also by the transverse clypeus (subtriangular in A. shelichovi) and more transverse head.
Distribution. China.
Etymology. Named after the nearly parallel-sided first metasomal tergite.
