(Figures 88, 103)  
 Description. Holotype. Female. Body length 2.1 mm, fore wing length 2.6 mm.   
 Head. Transverse in dorsal view, 1.9× as wide as long, weakly (1.1×) wider than mesoscutum. Vertex between eye and posterior ocellus shiny and almost without punctures. Temple shiny with indefinite punctures, not constricted. Face 0.8× as high as wide, shiny without punctures, inner margin of eyes subparallel-sided. Ocelli small, posterior tangent to anterior ocellus just touching posterior ocelli, distance between fore and hind ocellus as long as diameter of hind ocellus, POL:OD:OOL=4.6:1.7:4.2. Antenna almost as long as body length, loosely articulated, penultimate flagellomere cubic.   
 Mesosoma. Length:width:height = 40.0:25.0:25.0. Disc of mesonotum shiny, with small and shallow punctures, interspaces larger than diameter of puncture, extremely shallow to absent on hind margin, no trace of striate-punctation at posterior end of notaulic courses. Scutellar sulcus nearly straight, extremely narrow with shallow foveate groove. Scutellum highly shiny and polished without puncture entirely. Lateral polished field of scutellum reaching up to half length of scutellum; carinae absent anteriorly, shiny. Propodeum highly shiny, polished entirely, two short arms reaching out from orifice, spiracle not enclosed with keels. Mesopleuron highly polished, anterior part with superficial sparse punctures. Sternaulus indistinctly concave and smooth.   
 Legs. Hind coxa shiny, with several close punctures dorsally. Spines on outer side of third tibia stout, not dense. Inner spur 2/5 length of hind basitarsus, outer spur 1/3. Basitarsus of hind leg slightly longer than tarsomeres 2–4 combined (15.0:13.0), claws small.   
 Wings. Pterostigma 3.1× as long as its widest part. Vein 1-R1 weakly longer than pterostigma, 4.3× as long as its distance from apex of marginal cell. Vein r arising from middle of pterostigma, perpendicular to it, as long as width of pterostigma, 1.6× longer than 2-SR, distinctly angled at junction, 2-M 3/5 length of 2-SR and slightly shorter than 1-SR, 2-SR+M distinctly shorter than m-cu, and the latter nearly as long as 2-SR. First discal cell of fore wing weakly wider than high. Second submarginal cell of hind wing 1.6× wider than high. Vein cu-a nearly straight. Hind wing broad, length of 1-M shorter than distance between its distal extremity and apex of vannal lobe, and vannal lobe beyond its widest part slightly concave and hairless.   
 Metasoma. Nearly as long as mesosoma (38.0:40.0). T1 parallel-sided at basal two thirds, but strongly constricted towards apex at apical third, 3.0× longer than hind width, concave at basal third, turned-over part slightly shiny with several indefinite punctures laterally, longitudinal channel broad, shallow, and almost without rugosity with polished apical tubercle. T2 highly shiny and polished, 2.4× wider than long in the middle, straight apically. T3 2.0× longer than T2. Tergites posterior to T2 highly polished, shiny, and sparsely pubescent. Hypopygium broad, longer than apex of metasoma. Ovipositor sheath 1.3× longer than length of hind tibia, narrow of even size.   
 Colour. Black. Tegula dark. Palpi (except first segment maxillary palpi yellowish) and spurs pale yellowish. Antenna and ovipositor sheath dark brown to black. Labrum and mandible dark brown. Legs dark brown, except hind third of fore femur, mid tibia with tarsus, and basal third of hind tibia with tarsus yellowish. Wing membrane hyaline, 1-R1, C+SC+R, r and 2-SR yellowish brown, other alar veins pale yellow to pale, pterostigma pallid with darker border.   
 Variation. Body length 2.1–3.5 mm, fore wing length 2.6–4.0 mm. Basal half of hind tibia or only anterior part yellowish.   
 Male. Unknown.   
 Material examined. Holotype: 1♀, Mengxiu, Ruili, Yunnan, 1981.V.2–6, He Junhua, No. 812992. Paratypes: 1♀, Kuankuoshui Nature Reserve, Guizhou, 2010.VI.4, Tang Pu, No. 201002913; 1♀, Laodian, Mt. Tianmu, Zhejiang, light trap, 1998.VIII.23, Zhao Mingshui, No. 20001112.   
 Distribution. China (Guizhou, Yunnan, Zhejiang).   
 Etymology. The specific name “ aphanoiugum ” derives from the Latin “aphano-” and “iugum”, referring to the absence of carinae on the anterior part of the lateral polished field of scutellum.   
 Remarks. This species is similar to A. aphanoiugum Liu & Chen, sp. nov., but differs in the following: T1 strongly narrowed at apex (only weakly constricted apically in latter); T2 2.4× wider than long in the middle (4.3× wider than long in latter); and penultimate flagellomere cubic (1.3× longer than wide in latter).
