Redescription of Japanese species. ♀ (n= 12). Body length: 11.0–14.0 mm (12.0 mm in the lectotype of J. tamanukii).
Head. 0.6–0.7 × as long as wide in dorsal view. Clypeus 0.6 × as long as wide, strongly punctate. Face 0.6–0.9 × as long as wide, strongly and densely punctate, and weakly convex (Fig. 9). Frons weakly and densely punctate, with a median longitudinal carina (Fig. 9). Malar space 0.9–1.0 × as long as basal width of mandible. Subocular groove present (Fig. 9). Mandible striated except for apex (Fig. 9). Vertex and gena weakly and sparsely punctate. Occiput sparsely punctate. Occipital carina complete. OOL/OD = 1.4–1.6. POL/OD = 1.4–1.6. Antenna with 33– 36 flagellomeres; first flagellomere 1.2–1.4 × as long as second flagellomere.
Mesosoma. Propleuron densely punctate. Lateral area of pronotum densely punctate and transversely striated medially. Lateral part of collar punctate. Median lobe of mesoscutum weakly and densely punctate. Lateral lobe of mesoscutum sparsely punctate. Scutellum sparsely punctate, weakly convex in lateral view and forming a square to pentagon in dorsal view (Figs 17–19). Metapleuron extensively and strongly punctate (Fig. 10). Propodeum weakly carinate, roundly convex in lateral view (Fig. 10). Area externa of propodeum rugose and polished. Area dentipara punctate. Propodeal spiracle elongate (Fig. 10). Fore wing: length 9.0– 12.5 mm. Areolet absent (Fig. 11). Vein cu- a basad of vein M+cu (Fig. 11). Vein 3 rs-m distad of vein 2 m-cu (Fig. 11). Hind wing with vein cu-a intercepted middle, but sometimes above or below (intercepted above the middle in the lectotype of J. tamanukii) (Fig. 12). Hind femur 2.9–3.2 × as long as maximum depth in lateral view, with a blunt ventral tooth. Hind tibia 10.0–11.2 × as long as maximum depth. First hind tarsomere 2.2–2.5 × as long as second one, 2.4–2.8 × as long as inner spur.
Metasoma. T1 1.9–2.5 × as long as maximum width, 1.8–2.1 × as long as T2. T2 0.7–0.8 × as long as maximum width. T1 polished. Other tergites weakly punctate. Ovipositor sheath 2.1–2.3 × as long as hind tibia.
Coloration. Black (Figs 1–8). Antennal flagellum with a white band. Inner margin of eye, tegula, hind corner of pronotum, scutellum, postscutellum and propodeum more or less tinged right yellow. Front and middle legs, hind trochanter, hind trochantellus, apical 2/3 of hind tarsus yellowish brown. Face, frons, gena, clypeus, mesosoma, dorsal area of hind coxa and basal area of tergites usually black, but more or less yellow in some specimens (face yellow though black medially in the lectotype of J. tamanukii). Fore wing with a black marking on apical margin (Fig. 11).
♂ (n=11). Similar to females except as follows. Body length: 11.0– 14.5 mm (13.0 mm in the lectotype of J. yamatonis). Clypeus 0.5–0.6 × as long as wide. OOL/OD = 1.1–1.4. POL/OD = 1.1–1.6. Antenna with 37–41 flagellomeres (41 flagellomeres in the lectotype of J. yamatonis). Hind femur 2.9–4.7 × as long as maximum depth in lateral view. Hind tibia 8.4–11.8 × as long as maximum depth. Area externa and area dentipara rugose. First hind tarsomere 2.0–2.9 × as long as second one, 2.4–3.3 × as long as inner spur. T1 2.3–2.8 × as long as maximum width, 1.8–2.2 × as long as T2. T2 0.8–1.0 × as long as maximum width. More light-colored than females, T1 sometimes entirely yellow and the lateral to ventral area of hind coxa some× yellow (lateral to ventral area yellow and dorsal area brown to black in the lectotype of J. yamatonis).
Genitalia (n=4). Subgenital plate pentagonal with a basal angle obtuse (Fig. 16), its length ca. 0.7 × as long as aedeagus. Paramere short, basal part strongly projected toward the base of subgenital plate (Figs 13, 14). Aedeagus gently curved, its penis valve ca. 1.5 × as long as basal apodeme (Fig. 15).
