Description. Female (n=9). Body: slender, its length 6.5–9.0 mm.
Head 0.6 times as long as wide. Clypeus 0.8 times as long as wide, its upper 0.5 sparsely punctate. Face 0.6 times as long as wide. MSL 0.9 times as long as BWM. Upper part of occipital carina widely obscured medially. OOD 1.4 times as long as OD. IOD 1.4 times as long as OD. Antenna with 36–37 flagellomeres. F1 2.0 times as long as F2.
Mesosoma. Lateral area of pronotum largely smooth ventral 0.5. Epicnemial carina present laterally. Mesopleural fovea smooth. All carinae of propodeum strong and complete except median section of lateral longitudinal carina partly absent. Fore wing length 4.0–6.0 mm, with vein 2m-cu with one long bulla. Hind wing with C u 1 obscured. Fore coxa without ridge (Fig. 4 G). Hind femur 6.0 times as long as maximum depth in lateral view. Hind TS1 2.1 times as long as TS2.
Metasoma punctate. Punctures on posterior part of T1 to T4 slightly longitudinally striated by coalescent punctures. T1 1.4–1.5 times as long as maximum wide, its median dorsal carina nearly completely present, median longitudinal keel absent (Fig. 6 F). T2 0.9–1.0 times as long as maximum width (Figs. 1 F, 6 F, 7 F). T2–T4 with short median longitudinal keel only at base (Fig. 6 F). Ovipositor sheath 3.0–3.7 times as long as hind tibia.
Coloration (Figs. 1 F, 2 E, 5 F, 7 F). Head black except for: face excluding median longitudinal stripe, mandible excluding tip, malar space, palpi, ventral surface of scape and pedicel yellow; antenna sometimes tinged with dark brown excluding yellow area. Mesosoma black except for: pronotum excluding median black area, tegula, scutellum, subtegular ridge, large spot along mesopleural fovea on mesopleuron, postscutellum, hind margins of each axilla, metapleuron, posterior half of propodeum yellow. Wings hyaline with veins and stigma brown except for yellow wing base. Legs yellowish brown except for: apical 0.2 of hind tibia, apex of TS1–TS5, mid TS5, hind TS4 and TS5 brown. Metasoma black except for: posterior margin of T1–T3, postero-lateral margin of T5–T7, membranous area of sternites, subgenital plate whitish-yellow. Ovipositor reddish-brown. Yellow area of body sometimes expanded. Black area of mesosoma and metasoma sometimes partly tinged with red.
Male (n=12). Similar to female. OOD 1.2–1.4 times as long as OD; F1 1.7–2.0 times as long as F2. Hind femur 5.8–6.0 times as long as maximum depth. Subgenital plate with a short apodema sternalis, anterior margin convex (Fig. 9 J). Inner margin of paramere slightly concave near basal inner angle (Fig. 8 G). Penis valve of aedeagus ca. 2.3 times as long as basal apodeme (Fig. 9 K).

Distribution (Fig. 12). Japan (Ryukyus: Miyakojima Is.*, Ishigakijima Is. and Iriomotejima Is.) and Taiwan.
Biology. Unknown.
Remarks. This species can be easily distinguished from other all Japanese species by the following characters: upper part of occipital carina widely obscured medially (narrower than this species in all other species), ovipositor sheath relatively long, 3.0–3.7 times as long as hind tibia (less than 3.0 in all other species, Table 1), pronotum largely yellow (Fig. 2 E) (yellow area at most present dorsally in all other species) and mesopleuron with large yellow spot (Fig. 2 E) (absent in all other species). This species resembles A. karenkona Sonan, 1936 from Taiwan, in long ovipositor and the coloration of face, pronotum and mesopleuron, but it can easily distinguished from the latter by posterior part of propodeum and T1-T3 with conspicuous yellow markings (Fig. 1 F) (entirely black in A. karenkona).
