 Description. Holotype, ♀, length of body 3.4 mm, of fore wing 3.8 mm.   
Head. Transverse, width of head 1.9 × its lateral length, and 1.6 × wider than mesoscutum (Fig. 2I); antenna with 34 antennomere, third antennomere (including annellus) 1.3 × longer than fourth segment, length of third and fourth antennomere 4.0 and 4.0 × their width, respectively (Fig. 2G); length of maxillary palp twice height of head (Fig. 2K); eye in dorsal view 1.2 × as long as temple (Fig. 2I); eye in lateral view 1.1 × higher than wide (Fig. 2K); frons smooth (Fig. 2I); vertex and temple smooth (Fig. 2I); OOL:diameter of ocellus:POL= 11:3:3; face smooth, twice wider than high, rather convex medially and with a longitudinal ridge (Fig. 2J); clypeus small, semi-elliptical and smooth (Fig. 2J); mandible enlarged apically, dorsal tooth enlarged and lobe-shaped (Fig. 2L), ventral tooth medium-sized and lobe-shaped (Fig. 2M), middle tooth curved and acute, with no incision between first and second tooth (Fig. 2L), medial length of mandible 1.3 × its maximum width.  
Mesosoma. Length of mesosoma 1.4 × its height (Fig. 2C); pronope absent (Fig. 2I); medio-anteriorly pronotum crenulate, remainder of pronotum smooth; epicnemial area crenulated (Fig. 2C); precoxal sulcus widely crenulate, reaching middle coxa and anterior edge of epicnemial area (Fig. 2C); pleural sulcus crenulated (Fig. 2C); episternal scrobe small and deep; metapleuron reticulate-rugose ventrally, remainder smooth (Fig. 2C); mesoscutum with setae present at middle lobe (Fig. 2D); notauli incomplete, not impressed on mesoscutal disc (Fig. 2D); medio-posterior depression deep and droplet-shaped, almost extending to middle of mesoscutum, scutellar sulcus deep, with one longitudinal carina and some rugae, sulcus 3.0 × wider than its maximum length; scutellum smooth (Fig. 2D); surface of propodeum densely reticulate-rugose, areola absent posteriorly (Fig. 2E).  
Wings (Figs 2A–B). Pterostigma wide, 3.8 × longer than its maximum width. r:3-SR:SR1 = 5:18:55; 1-SR+M nearly straight; SR1 straight; r 0.4 × as long as width of pterostigma; cu-a postfurcal; 1-CU1:2-CU1 = 3: 20; 3-CU1 as long as CU1b; 2-SR:3-SR:r-m = 5:4:3; m-cu interstitial, converging to 1-M posteriorly; first subdiscal cell 2.5 × as long as wide; M+CU1 largely unsclerotized. Hind wing: M+CU: 1-M: 1r-m = 20:15:8; m-cu interstitial.  
Legs. Hind coxa smooth, without ventro-basal tubercle; tarsal claws slender, longer than arolium (Fig. 2N); length of femur, tibia and basitarsus of hind leg 4.6, 10.0 and 6.7 × their width, respectively; apical appendages of hind tarsal segments absent, segments ventrally with dense bristles (Fig. 2N).  
Metasoma. Length of first tergite 1.3 × its apical width, its surface longitudinally striate, its dorsal carinae remain separated medially (Fig. 2E); dorsope distinct; convexity of upper valve of ovipositor steep basally (Fig. 2H); setose part of ovipositor sheath 0.35 × as long as fore wing (total visible sheath 0.4 times), and 1.2 × as long as hind tibia (Fig. 2H).  
Colour. Black (Fig. 1); two basal antennomere of antenna, mandible brownish yellow; palpi yellow; metasoma except first tergite dark brown; legs (except dark brown apical part of hind tibia and hind tarsus) yellowish brown; pterostigma and veins light brown; wing membrane hyaline.  
Variation. Antennal segments of ♀ 34(1) or 35 (1).  
 Comparative diagnosis. This species is similar to A. incongrua Nees, but differs by having a wider face (twice wider than high versus 1.5–1.6 × in A. incongrua); length of third antennal segment 4 × its width (versus 5 times); vein m-cu of fore wing interstitial (versus antefurcal); first tergite of metasoma 1.3 × as long as its apical width (versus 1.5 times); distance between base of pterostigma and vein r 4.6 × longer than vein r (versus 6.5 times).   
 Etymology. Named “ hebeiensis ” because of the type locality of the holotype is situated in Hebei province.
