Description. Female (n = 6). Body length 11.4–13.5 (HT: 13.5) mm, polished and covered with punctures and brown setae.
Head 0.55–0.6 (HT: 0.57) × as long as wide in dorsal view, finely punctate and matt. Clypeus 3.0 × as broad as high, sparsely punctate, convex in lateral view, lower margin narrowly margined with a median concavity ( Fig. 40J View Fig ). Face 1.7–1.8 (HT: 1.8) × as broad as high, densely punctate ( Fig. 16B View Fig ), weakly convex medially in lateral view. Dorsal profile of gena as Fig. 38I View Fig . Occipital carina complete. Length of malar space 0.4 × as long as basal width of mandible. Mandible densely punctate, punctures partly united each other. POL 1.2–1.4 (HT: 1.2) × as long as OD. OOL 1.25–1.5 (HT: 1.25) × as long as OD. Antenna with 42–45 (HT: 42) flagellomeres. FL I 5.0 × as long as maximum depth, 1.7–1.8 (HT: 1.7) × as long as FL II.
Mesosoma densely punctate. Epomia absent. Mesoscutum with weak notaulus, interspace of punctures densely coriaceous and dull. Epicnemial carina present laterally and ventrally, its dorsal end situated near anterior margin of mesopleuron. Speculum with large smooth area. Mesopleuron finely striated in front of speculum. Propodeum with lateromedian longitudinal carina and pleural carina ( Fig. 16C View Fig ). Lateral longitudinal carina largely absent anteriorly. Posterior transverse carina partly obscured anteriorly. Area superomedia and area petiolaris largely rugose. Fore wing length 9.0–10.0 (HT: 10.0) mm. Areolet present, shortly petiolated, received vein 2m-cu at the outer angle ( Fig. 16D View Fig ). Fore wing with vein 2rs-m as long as vein 3rs-m. Fore wing vein 1cu-a postfurcal to vein M&RS. Nervellus subvertical, intercepted at the middle. Tarsal claws simple. Hind femur 4.2–4.7 (HT: 4.4) × as long as maximum depth in lateral view. Ratio of length of hind first to fifth tarsomeres 4.2– 4.3 (HT: 4.3): 2.0: 1.4–1.55 (HT: 1.5): 0.8–0.9 (HT: 0.8): 0.9–1.0 (HT: 0.9).
Metasoma minutely coriaceous. T I 1.8–1.9 (HT: 1.8) × as long as maximum width, largely finely punctate. T II 0.9–0.95 (HT: 0.95) × as long as maximum width, finely punctate. Ovipositor sheath 0.2 × as long as hind tibia.
Colouration ( Figs. 16A–D View Fig ). Body (excluding wings) black. Mandible partly tinged with yellowish brown to reddish brown. Fore tibia, fore and mid tibial spurs and tarsi yellowish brown. Ovipositor yellowish brown. Wings hyaline. Veins and pterostigma blackish brown except for dark brown wing base.
Male (n = 3). Similar to female. Clypeus 2.9–3.0 × as broad as high. Face 1.65 × as broad as high. POL 1.1–1.25 × as long as OD. OOL 1.2–1.25 × as long as OD. Antenna with 41–42 flagellomeres. FL I 4.4 × as long as maximum depth. Ratio of length of hind first to fifth tarsomeres 4.5– 4.6: 2.0: 1.6: 0.85–0.9: 1.0.
Distribution. Japan (Honshu).
Bionomics. Unknown.
Etymology. The specific name is from Latin “ nigra ” (black). This species has black body and legs.
Remarks. This species can be easily distinguished from other species by its almost entirely black body, including legs and antenna.
