Description. Female (n=6). Body: robust, its length 9.5–11.5 mm.

Head 0.6 times as long as wide. Clypeus 0.7–0.8 (HT: 0.7) times as long as wide, its upper 0.3 punctate. Face 0.6 times as long as wide, its striation strong. MSL 0.8–1.0 (HT: 1.0) times as long as BWM. Punctures on frons transversely striated by coalescent punctures above smooth area. OOD 1.8–2.0 (HT: 1.8) times as long as OD. IOD 1.2–1.6 (HT: 1.6) times as long as OD. Antenna with 43–46 (HT: 46) 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. Anterior transverse carina of propodeum complete. Posterior transverse carina of propodeum complete. Lateral longitudinal carina of propodeum complete. Lateromedian longitudinal carina of propodeum complete, sometimes median section weak. Fore wing length 7.5–9.0 (HT: 8.0) mm, with vein 2 m-cu with two bullae. Hind wing with Cu 1 present, nebulous. Fore coxa without ridge ( Fig. 4 View FIGURE 4 D). Hind femur 5.8–6.0 (HT: 5.8) times as long as maximum depth in lateral view. Hind TS1 2.5 times as long as TS2.

Metasoma punctate. Punctures on T1 to basal 0.5 of T4 slightly longitudinally striated by coalescent punctures. T1 1.4 times as long as maximum wide, its median dorsal carina nearly completely present, strong median longitudinal keel present ca. posterior 0.5 ( Figs. 1 View FIGURE 1 C, 6 C). T2 1.0 times as long as maximum width ( Figs. 1 View FIGURE 1 C, 6 C). T2–T4 with strong median longitudinal keel except for each apex ( Figs. 1 View FIGURE 1 C, 6 C, 7 C). Ovipositor sheath 2.3–2.5 (HT: 2.4) times as long as hind tibia.

Coloration (1 C, 3 A, 5 C, 7 C). Head black except for: clypeus, mandible excluding tip yellow; palpi yellowish-brown; antenna sometimes tinged with dark brown. Mesosoma black except for: upper margin of pronotum excluding median part, tegula, scutellum sometimes excluding pair of lateral basal spot, hind margins of each axilla yellow. Wings hyaline with veins and stigma brown except for yellow wing base. Fore and mid legs reddish-brown except for: coxae, trochanters and trochantelli yellowish-white; mid tarsus more or less tinged with brown. Hind leg dark brown to black except for: coxa, trochanter, trochantellus and base of femur, reddish-brown. Metasoma black except for: base of T1, posterior margin of T1 to T7, membranous area of sternites, apex of subgenital plate whitish-yellow; yellow area of T1 sometimes reduced; posterior white band of T2 and T3 sometimes narrowed. Ovipositor reddish-brown.

Distribution ( Fig. 10 View FIGURE 10 ). Japan (South Kyushu, Amamioshima Is., Okinawajima Is.).

Etymology. This species is named after the Latin term “ elegans ”, which origins from the elegant body coloration.

Biology. Unknown.

Remarks. This species closely resembles A. formosana Cushman, 1933 , in having a strong and long median longitudinal keel on T1 to T3 but it can be distinguished from the latter by the posterior transverse carina of propodeum complete (incomplete in A. formosana ) and hind coxa and femur dark brown to black ( Fig. 5 View FIGURE 5 C) (largely reddish-brown in A. formosana ).
