( Figs. 5A–C View Fig )

Type series. Holotype: JAPAN: NARO, F, Kagoshima Pref., Yakushima Is., Mt. Aiko-dake , 11. V. 1983, K. Konishi leg. Paratypes: JAPAN: NARO, F, Aomori Pref., Aomori City, Moyatouge , 27. VI. – 4. VII. 1992, T. Ichita leg. ; NARO, F, Aomori Pref., Aomori City, Moyasawa , 11. VII. 1992, T. Ichita leg.

Diagnosis. FL I 4.0–5.0 times as long as maximum depth in lateral view. Ovipositor sheath 0.43–0.44 times as long as fore wing and 1.25–1.3 times as long as hind tibia. Coxae reddish yellow to yellow.

Description. Female (n = 3). Body length 3.0–3.6 ( HT: 3.0) mm, polished and covered with silver setae.

Head 0.7 times as long as wide. Clypeus 1.9–2.1 ( HT: 2.0) times as broad as high, smooth. Supraclypeal groove deep. Face 1.7–1.8 ( HT: 1.7) times as broad as high, reticulate coriaceous, weakly convex medially in lateral view. Malar space 2.0–2.2 ( HT: 2.0) times as long as basal mandibular width. POL 1.2–1.4 ( HT: 1.4) times as long as OD. OOL 1.4 times as long as OD. Inner eye orbit weakly divergent ventrally. Occipital carina absent dorso-medially. Vertex reticulate coriaceous, weakly concave medially. Gena reticulate coriaceous. Mandible strongly twisted, upper tooth slightly longer than lower tooth. Flagellum with 17–18 ( HT: 17) segments, all segments longer than its maximum depth in lateral view. FL I 4.0–5.0 ( HT: 4.0) times as long as maximum depth in lateral view and 1.05–1.25 ( HT: 1.0) times as long as FL II.

Mesosoma reticulate coriaceous (sculpture on mesoscutum, metapleuron, and propodeum denser than other parts and thus these parts apparently matt). Mesoscutum with distinct notaulus, its posterior end situated near the middle of mesoscutum. Speculum with a conspicuous smooth area. Propodeum with posterior transverse carina, pleural carina and posterior section of lateromedian longitudinal carina. Fore wing length 2.85–3.0 ( HT: 2.85) mm. Vein rs-m of fore wing short. Vein 1cu-a of fore wing interstitial or slightly postfurcal. Vein 2r&RS of fore wing extends from pterostigma for its middle. Hind wing with nervellus intercepted at the middle. Hind femur 4.1–5.0 ( HT: 5.0) times as long as maximum depth in lateral view. Hind TS I 2.2–2.4 ( HT: 2.3) times as long as TS II. Hind TS II 4.0 times as long as maximum depth in lateral view. Tarsal claws simple.

Metasoma. T I 1.2–1.35 ( HT: 1.2) times as long as maximum width, densely reticulate coriaceous (apparently matt) ( Fig. 5 C View Fig ), strongly convex medially. T II 0.8–0.85 ( HT: 0.8) times as long as maximum width, reticulate coriaceous anteriorly, smooth posteriorly ( Fig. 5 C View Fig ), with a pair of narrow thrydia. T II to T VII largely smooth. Ovipositor sheath 0.43–0.44 ( HT: 0.44) times as long as fore wing and 1.25–1.3 ( HT: 1.3) times as long as hind tibia.

Coloration ( Figs. 5A–C View Fig ). Body (excluding wings and legs) black to blackish brown. Mandible, basal segments of antenna, tegula, thridium, posterior part of T II, and ovipositor yellowish brown. Palpi and membranous sections of metasomal sternites whitish yellow. Wings hyaline. Veins and pterostigma pale brown to brown. Legs reddish yellow to yellow.

Male. Unknown.

Distribution. Japan (Honshu and Yakushima Is.).

Etymology. The specific name is from the Latin longi- (long) plus cauda (tail). This species has a long ovipositor.

Remarks. This species can be distinguished from other species by the long ovipositor.
