Mesosoma black except for: small spot before tegula on pronotum, tegula, apex of scutellum, hind margins of each axilla yellow. Wings hyaline with veins and stigma brown except for yellow wing bases. Legs reddish-brown except for: apex of mid TS5, apex of claws, apex of hind femur, subbasal band and apical 0.2 of hind tibia, hind tarsus including claws dark brown; hind tibia excluding black area, hind tibial spur whitish-yellow. Metasoma black except for: membranous area of sternites, apex of subgenital plate whitish-yellow. Ovipositor reddish-brown. Mesosoma sometimes tinged with red. Malar space and postscutellum sometimes tinged with yellow. Subbasal black band of hind tibia sometimes erased. Metasomal tergites sometimes posteriorly or entirely tinged red.

Male (n=7). Similar to female. MSL 0.6 times as BWM; Flagellum with 42–44 segments. Subgenital plate with a long apodema sternalis, anterior margin slightly concave ( Fig. 9 View FIGURE 9 P). Inner margin of paramere strongly concave near basal inner angle (Fig. 8 F). Penis valve of aedeagus ca. 1.9 times as long as basal apodeme ( Fig. 9 View FIGURE 9 Q). Ventral surface of pedicel yellow.

Distribution ( Fig. 13 View FIGURE 13 ). Japan (Hokkaido, Honshu and Kyushu*), China and Far East Russia.

Biology. Unknown.

Remarks. This species may be confused with A. bipunctioria and A. honmai but it can be distinguished by the combination of characters: yellow area of upper margin of pronotum always present as a small spot before tegula (usually present as yellow stripe along upper margin in A. bipunctoria and A. honmai ), female MSL 0.8 times as long as BWM (0.5–0.7 in A. bipunctoria , 0.9 in female A. honmai and 0.5–0.6 in male A. honmai ) and T1 1.4–1.5 times as long as wide (1.2–1.3 in female of A. bipunctoria , 1.6–1.9 in honmai but 1.4 in male of A. bipunctoria ).
