Description. Female (n=5). Body: robust, its length 9.0– 9.5 mm.
Head 0.6 times as long as wide. Clypeus 0.8–0.9 times as long as wide, its upper 0.5 sparsely punctate. Face 0.6 times as long as wide. MSL 0.9–1.0 times as long as BWM. OOD 1.6–1.8 times as long as OD. IOD 1.2 times as long as OD. Antenna with 41–43 flagellomeres. F1 2.0 times as long as F2.
Mesosoma. Lateral area of pronotum largely smooth ventral half. Epicnemial carina absent laterally. Mesopleural fovea narrowly smooth. Anterior transverse carina absent. Posterior transverse carina of propodeum usually completely present, or sometimes absent. Lateral longitudinal carina of propodeum absent. Lateromedian longitudinal carina of propodeum largely absent, sometimes present basally. Fore wing length 7.0 mm, with vein 2 m -c u with two bullae. Hind wing with Cu 1 present, nebulous. Fore coxa with distinct ridge (Fig. 4 A, B). Hind femur 6.0–6.2 times as long as maximum depth in lateral view. Hind TS1 2.5 times as long as TS2.
Metasoma punctate. Punctures on T1–T4 slightly longitudinally striated by coalescent punctures. T1 1.4 times as long as maximum wide, its median dorsal carina present ca. basal 0.5, short median longitudinal keel sometimes present posteriorly (Fig. 6 A). T2 0.9–1.0 times as long as maximum width (Figs. 6 A, 7 A). T2 and T3 with short median longitudinal keel except for near each apex (Fig. 6 A). T4 sometimes with short median longitudinal keel basally. Ovipositor sheath 2.1–2.2 times as long as hind tibia.
Coloration (Figs. 1 A, 2 A, 5 A, 7 A). Body weakly polished by dark blue reflection. Head black except for: clypeus, mandible excluding tip yellow; palpi yellowish-brown; antenna sometimes tinged with dark brown. Mesosoma black except for: small spot before tegula on pronotum, tegula, hind margins of each axilla yellow. Wings hyaline with veins and stigma brown except for yellow wing base. Legs yellowish-brown except for: hind coxa and femur reddish-brown; base and apex of hind femur, hind tibia, tibial spur and tarsus brown to dark brown; base of hind tibia more or less paler than other part; apex of hind coxa sometimes darkened. Metasoma black except for: membranous area of sternites, apex of subgenital plate whitish-yellow. Ovipositor reddish-brown. Body sometimes tinged with reddish-brown.

Distribution (Fig. 10). Japan (Hokkaido and Honshu*).
Biology. Unknown.
Remarks. This species can be easily distinguished from other Japanese species by the following combination of characters: epicnemial carina absent laterally, scutellum black, fore coxa with distinct ridge (Fig. 4 A, B) and median dorsal carina of T1 present ca. basal 0.5 (Fig. 6 A). This species resembles A. genalis (Moller, 1883) and it can be easily distinguished from the latter by MSL 0.9–1.0 times as long as BWM (ca. 1.5 times as long as BWM in A. genalis).
