(Figures 76, 102)  
 Description. Holotype. Female. Body length 3.0 mm, fore wing length 3.0 mm.   
 Head. Transverse in dorsal view, 2.0× as wide as long, nearly 1.1× wider than mesoscutum. Vertex between eye and posterior ocellus shiny, densely punctate. Temple slightly shiny, indefinitely punctate, not constricted. Face 0.7× as high as wide, shin with small, even punctures, sparsely pubescent, inner margin of parallel-sided. Ocelli not large, posterior tangent to anterior ocellus just touching posterior ocelli, distance between fore and hind ocellus about as long as diameter of hind ocellus, POL:OD:OOL=5.0:2.0:5.0. Antenna much shorter than body length, relatively thick, not shrunken apically, loosely articulated, penultimate flagellomere quadrate.   
 Mesosoma. Length:width:height = 49.0:32.0:38.5. Disc of mesonotum wide, slightly shiny with dense and coarse punctures. Punctures tend to be coarser along notaulic courses and even confluent or rugulose-punctate at the end of it (without longitudinal striations), interspaces smaller than diameter of puncture. Scutellar sulcus curved, narrow with dense carinae inside. Scutellum highly shiny and smooth, except for numerous fine punctures, median length as long as basal width. Lateral polished field of scutellum reaching just over half length of scutellum. Propodeum slightly shiny, with much irregular carinae anterio-laterally, elsewhere shiny, smooth and with some carinae, areolation well defined with V-shaped apex and with indistinct transversal carina basally, costulae well defined. Mesopleuron highly shiny, its large anterior part with very strong, fine punctures, weakly strigulate on and above sternaulus.   
 Legs. Hind femur thin, 3.4× longer than wide. Hind coxa shiny with dense punctures above (basally). Spines on outer side of third tibia relatively dense. Inner spurs of hind tibia half length of hind basitarsus, outer spur 1/3. Basitarsus of hind leg as long as tarsomeres 2–4 combined, claws of normal size.   
 Wings. Pterostigma 2.9× as long as its widest part. Vein 1-R1 1.1× longer than pterostigma, 4.8× as long as its distance from apex of marginal cell. Vein r arising from middle of pterostigma, slightly curved outwards, slightly longer than width of pterostigma, r 1.4× longer than 2-SR, actually curved at junction, 2-M 2/3 length of 2-SR and slightly shorter than 2-SR+M, the latter as long as 1-SR, cu-a as long as 2-SR. First discal cell of fore wing hardly 1.1× wider than high. Second submarginal cell of hind wing as wide as high. Vein cu-a nearly straight. Hind wing much broad, length of 1-M much shorter than distance between its distal extremity and apex of vannal lobe, and vannal lobe beyond its widest strongly concave and without setae.   
 Metasoma. Nearly 1.2× longer than mesosoma (58.0:49.0). T1 narrow, parallel-sided on basal half, slightly, but distinctly, converged form middle towards apex, 2.1× longer than hind width, concave at basal third, turned-over part slightly longer than wide, slightly shiny and scrobiculate, longitudinal trough absent, apical tubercle small, shiny and polished. T2 shiny and smooth, narrow, 3.3× wider than long in the middle, slightly curved apically. T3 2.6× longer than T2. Tergites posterior to T2 shiny, smooth, sparsely pubescent. Hypopygium slightly longer than apex of metasoma. Ovipositor sheath about as long as length of hind tibia. Ovipositor relatively thin, slightly curved with an indistinct apical attenuation.   
 Colour. Black. Tegula black. Palpi yellowish and spurs pale yellowish. Antenna and ovipositor sheath dark brown. Labrum and mandible reddish brown. Legs dark brown to black, except apical half of fore femur, fore tibia with tarsus, apex of middle femur, middle tibia with tarsus, and basal 2/5 of hind tibia yellow to yellowish brown. Wing membrane hyaline, C+SC+R, 1-R1, pterostigma (slightly paler medially), r, 2-SR and 2-M brown, the rest more or less pale brownish.   
 Variation. Body length 2.5–3.8 mm, fore wing length 2.6–3.6 mm. Hind basitarsus yellowish brown to blackish brown basally.   
 Male. Unknown.

 Distribution. China (Guizhou, Hainan, Yunnan, Zhejiang).   
 Etymology. The specific name “ scrobiculatus ” derives from the Latin, referring to T1 scrobiculate.   
 Remarks. This species is similar to A. nixoni Song & Chen, but differs in the following: penultimate flagellomere quadrate (one-and-two-third longer than wide in latter); ovipositor thinner (thicker in latter); and scutellar sulcus curved, narrow (straight, wide in latter).
