Figure 6
Description. Female. Body length ca. 1.8 mm, fore wing length ca. 2.3 mm.
Head. Transverse in dorsal view, 2.0 as wide as long (23.2:11.5) and slightly narrower than mesosoma (23.2:25.0). Temple shiny, more or less impunctate, rather constricted. Face less transverse, hardly 0.8 as high as wide, relatively shiny, slightly bulging medially, coarsely punctate, sparsely pubescent (Fig. 6 b), inner margin of eyes subparallel. Ocelli small, distance between fore and hind ocellus indistinctly greater than diameter of a hind ocelli, posterior tangent to the anterior ocellus touching the posterior pair, POL:OD:OOL=3.0:1.6:3.8. Antenna almost as long as body length, penultimate antennomere subcubic.
Mesosoma. Length to breadth and height 31.0:25.0:23.0. Disc of mesonotum relatively dull, densely heavily punctate anteriorly, punctation becomes smaller and sparser posteriorly. Scutellar sulcus a little curved, narrow with sparse carinae in between. Scutellum polished with a few of indistinctly punctures. Propodeum highly shiny, polished, without punctures anteriorly, several radiating carinae around nucha. Mesopleuron highly polished, its anterior half with shallow punctation of even size.
Legs. Spines on outer side of hind tibia sparse. Inner spur of hind tibia longer than the outer one, almost half length of hind basitarsus, outer spur almost 1/3 length of hind basitarsus. Hind basitarsus almost as long as tarsal segments 2–4 combined.
Wings. Pterostigma 2.5× as long as its widest part. Vein 1-R1 (metacarp) 1.4× longer than pterostigma, almost closing the radial cell. Vein r arising from middle of pterostigma, as long as width of pterostigma, vein r as long as vein 2-SR, both veins distinctly angled at their meeting, vein 2-M 2/3 length of vein 2-SR. 1st discal cell slightly wider than high. Vein cu-a straight. Vannal lobe beyond its widest part straight and without projecting setae.
Metasoma. Slightly shorter than thorax (29.0:31.0). T1 strongly narrowed to apex, basal width 2.7× hind width, and relatively short, almost 1.6× longer than basal width. Concave at basal 2/5, highly shiny and polished with scattered independent punctures. T2 triangular, curved into T3, sulcus between T2 and T3 indistinct. 2.5× wider than long in the middle. T3 1.6× as long as T2 (6.5:4.0). Tergites after T1 relatively shiny, smooth. Hypopygium shorter than apex of abdomen. Ovipositor sheath almost as long as hind tibia, relatively thin.
Colour. Body black, except T1 and anterior half of T2 bright yellow. Scape and pedicel yellow. Flagellum, tegulae and ovipositor sheath brown. Labrum and mandible reddish brown. Palpi and spurs of tibiae pale yellow. Legs bright reddish brown, coxae 1–3 dark, most parts of hind femur and basal 2/3 of hind tibia testaceous, and margins of hind femur and apical 1/3 of hind tibia darker. Fore wing membrane hyaline, faintly brown, vein 1-R1, C+SC+R and pterostigma brownish, r, 2-SR, 2-M and other veins light brown.
Male. Unknown.
Host. Unknown.
Material examined. Holotype: ♀, Jiangfengling, Hainan, 2007. VI.5–7, Weng Liqiong, No. 200806432.
Distribution. China (Province: Hainan).
Etymology. The specific name “ hainanensis ” refers to the type locality.
Remarks. This species is very similar to A. magnioculus Liu & Chen, sp. n., but can be separated by the followings: penultimate antennomere subcubic (in the latter species 1.7× longer than wide); ovipositor sheath almost as long as hind tibia (in the latter species 1.3× as long as hind tibia); and T1 narrower than that of A. magnioculus Liu & Chen, sp. n.
