Description. Female (n=4). Body: robust, its length 10.0–12.0 mm.

Head 0.6 times as long as wide. Clypeus 0.7–0.8 times as long as wide, its upper 0.5 punctate. Face 0.6 times as long as wide. MSL 0.7 times as long as BWM. OOD 1.4 times as long as OD. IOD 1.4 times as long as OD. Antenna with 47–48 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 on lateral section. Posterior transverse carina of propodeum complete. Lateral longitudinal carina of propodeum present, its median section sometimes partly absent. Lateromedian longitudinal carina of propodeum usually indistinct except for base, sometimes median section reduced as weak ridge. Fore wing length 8.0– 8.5 mm, with vein 2 m-cu with two bullae. Hind wing with Cu 1 present, nebulous. Fore coxa without ridge (Fig. 4 K). Hind femur 6.5–6.6 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, short median longitudinal keel sometimes present posteriorly (Fig. 6 J). T2 0.9–1.0 times as long as maximum width (Figs. 6 J, 7 J). T2 and T3 with short median longitudinal keel except for posterior part (Fig. 6 J). Ovipositor sheath 2.9–3.0 times as long as hind tibia.

Coloration (Figs. 1 J, 2 I, 5 J, 7 J). Body weakly polished with dark blue reflection. Head black except for: clypeus, mandible excluding tip, malar space along mandible, ventral apex of pedicel yellow; palpi yellowishbrown; antenna sometimes tinged with dark brown. Mesosoma black except for: upper margin of pronotum excluding median part, tegula, scutellum excluding basal spot, postscutellum, hind margins of each axilla yellow. Wings hyaline with veins and stigma brown except for yellow wing base. Fore and mid legs yellowish-brown except for fore coxa partly tinged pale yellow. Hind leg dark brown except for dorsal surface of coxa, trochanter, trochantellus, base of tibia, tibial spur more or less tinged yellow. Metasoma black except for: membranous area of sternites, apex of subgenital plate whitish-yellow. Ovipositor reddish-brown. Subtegular ridge sometimes tinged with yellow. Fore and mid coxae, trochanters and trochantelli sometimes entirely pale yellow.

Male. Not examined, but see male specimens used by Momoi (1965) deposited in SEHU.

Specimens examined. JAPAN [Hokkaido] 1F, Sapporo city, Hokkaido University, 27. vii. 1996, M. Matsuda leg. (KPMNH: KPM-NK 5001231). [Honshu] 1F, Aomori Pref., Aomori city, Kasamatsu-touge, 15. viii. 1992, T. Ichita leg. (NIAES); 1F, Nagano Pref., Hiziri highland, 2. viii. 1965, S. Katsuya leg. (NIAES); 1F (lectotype), Mie Pref., Toba, 22. vi. 1922, M. Yanagihara leg. (SEHU).

Distribution (Fig. 13). Japan (Hokkaido, Honshu and Shikoku), Russian Far East.

Biology. The following hosts are recorded in Japan: Archips oporanus (Linnaeus), Archips pulcher (Butler), Homona issikii Yasuda (Momoi, 1965) and Choristoneura diversana (Hübner) (Kamijo, 1973).

Remarks. This species resembles A. yamato sp. nov., but it can be distinguished from the latter by the length of ovipositor sheath 2.9–3.0 times as long as hind tibia (1.9–2.0 times in A. yamato sp. nov.), hind coxa with yellow marking dorsally (Fig. 5 J) (without yellow marking dorsally in yamato: Fig. 5 K), and the median dorsal carina of T1 at least present basal 0.6 (Fig. 6 J) (largely obsolete posteriorly, distinct area shorter than basal 0.5 in A. yamato: Fig. 6 K).
