Description. Female (n = 2). Body matt; covered with setae; body length 7.1–7.6 (HT: 7.6) mm.

Head 0.6 × as long as wide in dorsal view. Clypeus 2.0 × as wide as long, slightly punctate; lower margin subtruncate; sharp in lateral view. Face 0.35 × as long as minimum width; slightly convex medially. Anterior tentorial pit small. Frons slightly concave above antennal sockets; sparsely punctate dorsally; transversely rugulose above antennal sockets. POL 1.3 × as OD. OOL 1.3–1.4 (HT: 1.3) × as OD. Occiput and vertex finely and densely punctate. Dorsal profile of gena weakly rounded in dorsal view; width gradually narrowing posteriorly ( Fig. 33D). Occipital carina complete. Malar space 1.0–1.1 (HT: 1.0) × as long as basal width of mandible. Mandible flat at base; lower tooth equal in length of upper tooth. Antenna with 21–22 (HT: 22) flagellomeres; not flattened and tapped. FL I 3.2 × as long as maximum depth in lateral view, 0.8 × as long as FL II.

Mesosoma. Pronotum coriaceous ventrally; punctate dorsally. Epomia short; dorsal end situated slightly above collar. Mesoscutum densely punctate. Notaulus weak; posterior end not reaching centre of mesoscutum. Scutellum punctate; convex in lateral view. Mesopleuron punctate; punctures partly united into groove-like foveola; with conspicuous small smooth area around speculum ( Fig. 33E). Epicnemial carina present laterally and ventrally. Sternaulus deep in anterior 0.6 of mesopleuron. Metapleuron punctate; with complete juxtacoxal carina. Propodeum coriaceous with fine and sparse punctures; anterior transverse carina absent ( Fig. 33G); posterior transverse carina complete; lateromedian longitudinal carina weakly present, sometimes partly absent; lateral longitudinal carina weakly present to complete; pleural carina complete; area superomedia weakly defined, more or less triangular-shape; apophysis absent; spiracle round. Fore wing length 5.6–5.9 (HT: 5.9) mm. Areolet slightly shorter than long; width steeply narrowing anteriorly; received vein 2m-cu basal than middle ( Fig. 33F). Fore wing vein 1cu-a interstitial to vein M&RS ( Fig. 33F). Nervellus subvertical; intercepted near posterior end of vein ( Fig. 33F). Hind femur reticulate coriaceous; 4.3–4.4 (HT: 4.4) × as long as maximum depth in lateral view. Tarsal claws simple.

Metasoma. T I 1.8 × as long as maximum width; lateromedian carina absent; dorso-lateral carina complete. T II 0.75–0.85 (HT: 0.85) × as long as maximum width. Thyridium present; somewhat distant from (by more than length of thyridium) anterior margin of T II; flat to slightly depressed; ca. 1.0 × as wide as length. Ovipositor sheath 0.95 × as long as hind tibia, 1.7–1.75 (HT: 1.7) × as long as T I. Ovipositor straight; apex sharp; apex of lower valve with teeth ( Fig. 79D).

Colouration ( Figs. 33A–G). Body (excluding wings) black to blackish-brown. Setae silver. Subapical part of mandible, lower part of clypeus, ventral surface of apical part of flagellum, posterior margins of T I and T II tinged with brown to reddish-brown. FL VI to FL X with white markings. Apical parts of fore and mid legs more or less tinged with brown. Tibial spurs of all legs yellow to yellowish-brown. Base of each hind tarsomere narrowly tinged with yellowish-brown. Membranous part of metasomal sternites yellow to ivory. Apex of metasoma with ivory marking. Thyridium and ovipositor reddish-brown. Wings hyaline. Veins and pterostigma blackish-brown to brown except for yellowish-brown to yellow wing base.

Male. Unknown.

Distribution. Japan (Honshu).

Bionomics. Unknown.

Etymology. The specific name is from the type locality and my hometown, Minami-ashigara City, a city of Kanagawa Prefecture.

Remarks. This species resembles J. coreensis and J. taniguchiae in the black body but can be distinguished by the ovipositor sheath 1.1 × as long as hind tibia (0.65–0.8 × in J. coreensis ; 1.43 × in J. taniguchiae ), the T I 1.8 × as long as maximum width (2.05–2.35 × in J. coreensis ), and the hind tibia without white base (with white base in J. taniguchiae ).
