( Figures 97 View FIGURE 97 , 103 View FIGURE 103. 77–97 )
Description. Holotype. Female. Body length 2.2 mm, fore wing length 2.5 mm.
Head. Transverse in dorsal view, 2.1× as wide as long, nearly (1.1×) wider than mesoscutum. Vertex between eye and posterior ocellus shiny with small punctures. Temple weakly dull with punctures, slightly constricted. Face nearly 0.8× as high as wide, dull with strong punctures, inner margin of eyes slightly constricted towards apex. Ocelli small, posterior tangent to anterior ocellus virtually transecting posterior ocelli, distance between fore and hind ocellus larger than diameter of hind ocellus, POL:OD:OOL=6.0:2.0:4.0. Antenna slightly shorter than body length, closely articulated, penultimate flagellomere 1.4× longer than wide.
Mesosoma. Length:width:height = 40.0:27.5:32.0. Disc of mesonotum shiny, with dense and strong punctures, interspaces shorter than diameter of puncture, characteristic dense, silvery, pubescence, on posterior half of mesoscutum pubescence becomes longer and silky, rugose-punctate at posterior end of notaulic courses. Scutellar sulcus curved, narrow with carinae in between. Scutellum dull with small punctures entirely, pubescence dense as posterior half of mesoscutum, wide posteriorly. Lateral polished field of scutellum reaching over half length of scutellum. Propodeum shiny, two short arms reaching out from orifice, spiracle not enclosed with keels, only some short carinae behind spiracle. Mesopleuron highly polished, most parts distributed with hairy punctures, becoming rugose along hind margin.
Legs. Hind coxa dull, with hairy bumps dorsally. Spines on outer side of third tibia long, not dense. Inner spur 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 3.3× as long as its widest part. Vein 1-R1 0.8× length of pterostigma, 1.8× as long as its distance from apex of marginal cell. Vein r arising from middle of pterostigma, slightly oblique outwards, slightly shorter than width of pterostigma, 1.2× longer than 2-SR, indistinctly angled at junction, 2-M half length of 2-SR and slightly shorter than 1-SR, 2-SR+M as long as m-cu and 2-SR. First discal cell of fore wing 1.2× wider than high. Second submarginal cell of hind wing 1.1× wider than high. Vein cu-a nearly straight. Hind wing not broad, length of 1-M not shorter than distance between its distal extremity and apex of vannal lobe, and vannal lobe beyond its widest part straight and hairless.
Metasoma. Nearly 1.1× longer than mesosoma (43.5:40.0). T1 nearly parallel-sided, slightly constricted towards apex at apical third, 1.9× longer than hind width, concave at basal half, turned-over part slightly shiny with close, indistinct punctures medially, longitudinal channel short, shallow, and almost without rugosity, rugose laterally and apical tubercle polished. T2 slightly shiny and slightly rough, 4.6× wider than long in the middle, nearly straight apically. T3 2.2× longer than T2. Tergites posterior to T2 highly polished, shiny, and pubescent. Hypopygium not longer than apex of metasoma. Ovipositor sheath 1.1× longer than length of hind tibia, narrow of even size, hairs sparse and long.
Colour. Black. Tegula dark brown. Palpi and spurs pale yellowish. Antenna and ovipositor sheath dark brown to black. Labrum and mandible dark brown. Legs dark, except most parts of fore femur with tibia and tarsus, mid tarsus (except apical segment brown) and mid tibia fumous, hind tibia and tarsus brown entirely. Wing membrane hyaline, 1-R1 brown, C+SC+R, r and 2-SR pale yellow, other alar veins pale almost colourless, pterostigma pallid with darker border.
Variation. Body length 2.2–2.8 mm, fore wing length 2.4–3.3 mm. Propodeum of some specimens with fine rugosity inside and outside of the imaginary areola.
Male. Unknown.

Distribution. China (Fujian, Guangdong, Hainan, Sichuan, Zhejiang).
Etymology. The specific name “ setosus ” derives from the Latin, referring to pubescence on scutellum dense similar to the posterior half of the mesoscutum.
Remarks. This species is similar to A. mutilia Nixon , but differs in the following: ovipositor sheath only indistinctly longer than length of hind tibia, narrow of even size (1.3×, falcate apically in latter); T1 rugose to punctate-rugulose (smooth, almost unsculptured in latter); and head above not grayish (slightly grayish owing to dense pubescence in latter).
