Type material. Holotype ♀ ( FAFU). “ CHINA | Chebaling | Shaoguan City | Guangdong Province | 25.v.2002 | LIU Changming / Holotype ”.  

Paratypes 2♀ ( FAFU), same data as holotype.

Description of holotype. FEMALE. Body length excluding ovipositor sheath 2.6 mm.

Head ( Figs 7A, D, E View FIGURE 7 ) primarily bright green with vertex, gena and occiput metallic bluish-green. Head in frontal view ( Fig. 7D View FIGURE 7 ) 1.31× wider than high; frons coriaceous-granular, parascrobal region rugose, with two rows of hairlike setae; interantennal region transversely reticulate-imbricate, with hair-like setae; lower face reticulate-rugose, and medially angulate, with white slightly lanceolate setae; scrobal depression with scrobe deep, lateral margin strongly carinate, dorsally separated from anterior ocellus by distance equal to 1.2× longitudinal diameter of anterior ocellus; distance between eyes below 2.3× distance between eyes above, lower orbit above level of ventral margin of torulus; distance between toruli greater than distance between torulus and clypeal margin, and 1.69× distance between torulus and orbit. Head in dorsal view ( Fig. 7E View FIGURE 7 ) with width about 2.0× length, with interocular distance about 0.3× head width and less than width of eye; vertex transversely reticulate to strigose, with brown hair-like setae. Head in lateral view ( Fig. 7A View FIGURE 7 ) lenticular with face evenly convex, 1.31× higher than long; gena reticulate to imbricate, with white hair-like setae; eye height 1.34× eye width in lateral view; malar space 0.32× eye height; distance between a posterior ocellus and inner orbit: distance between posterior ocelli: distance between the anterior and a posterior ocellus: maximum diameter of a posterior ocellus = 3:9: 7: 5. Antenna ( Fig. 7C View FIGURE 7 ) with scape light yellowish-brown, pedicel slightly darker than scape, flagellum dark brown; scape 0.41 mm; relative length(width) of scape = 30(6); pedicel 8(4.5); first to eighth funiculars: 4(4), 11(4.5), 11(5.5), 11(6.5), 9(7), 7(7), 7(7.5), 6(7.5); clava 19(9). Maxillary and labial palpi dark brown.

Pronotum ( Fig. 7G View FIGURE 7 ) yellowish-brown, except spiracular rim dark brown; in dorsal view pentangular, weakly coriaceous, divided medially, with hair-like setae. Mesoscutum ( Fig. 7G View FIGURE 7 ) with anterior convex part of medial lobe yellow without metallic luster, more-or-less triangular, 0.63× total length of mesoscutum, coarsely punctate-reticulate with white lanceolate setae, posterior concave part of mesoscutum slightly brownish-yellow, smooth, and broadly setose with white setae medially; lateral lobe with inclined inner surface slightly alutaceous, with white setae along lateral margin. Scutellar-axillar complex ( Fig. 7G View FIGURE 7 ) convex, coarsely reticulate, scutellum 1.63× longer than broad. Brachypterous; fore wing ( Figs 7F, H View FIGURE 7 ) 1 mm in length, with apex rounded, extended 3/5 length of gaster; basal third hyaline and apical two-thirds with yellowish-brown setae, but with one hyaline cross band behind apex of marginal vein with white setae and infuscate region basal to hyaline band 3.1× wider than hyaline band; basal region with basal cell bare basally, and with a few white setae apically, cubital and vanal areas with comparatively inconspicuous white setae ( Fig. 7H View FIGURE 7 ); submarginal vein: marginal vein: postmarginal vein: stigmal vein = 10: 7.5: 2.4: 1.1. Tegula yellowish-brown ( Fig. 7A View FIGURE 7 ). Mesopectus ( Fig. 7A View FIGURE 7 ) brownish, finely meshlike reticulate, and with entirely white lanceolate setae; acropleuron yellowish with purple metallic luster, longitudinally coriaceous-imbricate, and anterior 1/4 with white lanceolate setae. Metanotum and propodeum dark brown ( Fig. 7G View FIGURE 7 ); propodeum with plical depression broadly U-shaped, plical region sublinear medially ( Fig. 7G View FIGURE 7 ). Front and middle legs ( Figs 7A, B View FIGURE 7 ) yellowish-brown except dorsal margin of mesofemur brown and mesotarsal pegs black; hind leg brown except tarsus light yellowish-brown; front leg with ventral margin of femur evenly arched, not toothed; middle leg with mesotibial apical pegs in a patch, mesotibial apical spur pale, slightly shorter than basitarsus, mesotarsus with all tarsomeres pale in contrast with dark mesotarsal pegs; hind leg with basitarsus slightly shorter than following three tarsomeres combined.

Gaster ( Figs 7A, B View FIGURE 7 ) mostly dark brown with metallic luster under some angles of light and base partly yellowish-white, apex of syntergum and ovipositor pale yellowish-brown; gaster as long as mesosoma, finely alutaceous, with hair-like setae; ovipositor not exserted.

MALE. Unknown.

Variation. Female body length about 2.6–3.4 mm; submarginal vein: marginal vein: postmarginal vein: stigmal vein = 10: 8.6–9.1: 2:1; one paratype with the body light yellow.

Etymology. The species name is a combination of the Latin words ‘ flavus ’ (yellow) and ‘ aeratus ’ (covered with bronze or coppery), in reference to the mesosoma being mostly yellow with coppery luster.

Host. Unknown.

Distribution. ORIENTAL: China (Guangdong).

Remarks. Females of A. flavaeratus   most closely resemble those of A. gastropachae   , but are differentiated primarily by the features given in the key.
