Description. Female (n=2). Body polished, covered with slightly brownish silver setae, length 10.5–11.0 (HT: 11.0) mm.
Head 0.5 × as long as wide, punctate. Clypeus 0.5 × as long as maximum wide, strongly convex in lateral view ( Fig. 1C View Fig ), its apical margin rounded, without a median tooth or convexity ( Fig. 1B View Fig ). Face 0.36–0.4 (HT: 0.36) × as long as maximum wide, finely coriaceous, slightly convex medially in lateral view. Frons densely punctate except for a smooth area above antennal sockets, with a pair of distinct concavity on the smooth area. Length of malar space 0.8 × as long as basal mandibular width. Base of mandible slightly convex. Upper tooth of mandible almost as long as lower tooth ( Fig. 1B View Fig ). OD: POL: OOL = 1.0: 1.7: 1.8–2.0 (HT: 2.0). Flagellum with 34–35 (HT: 35) segments. FL I 5.0 × as long as maximum depth in lateral view and 1.36 × as long as FL II.
Mesosoma. Lateral aspect of pronotum punctate dorsally, longitudinally strigose ventrally and posteriorly. Epomia present, short. Posterior end of notauli barely reached to middle of mesoscutum. Mesoscutum densely punctate. Scutellum punctate. Mesopleuron largely rugose ( Fig. 5B View Fig ), without a smooth area on speculum. Mesosternum without a median part of posterior transverse carina. Metapleuron reticulate rugose ( Fig. 2C View Fig ). Juxtacoxal carina present but indistinct partly ( Fig. 2C View Fig ). Propodeum punctate on area externa and strongly reticulate rugose on areas behind anterior transverse carina ( Fig. 5E View Fig ). Anterior section of lateromedian longitudinal carina present except for anterior part.Anterior transverse carina complete except for median part absent ( Fig. 5E View Fig ). Posterior transverse carina complete except for median part absent ( Fig. 5E View Fig ). Pleural carina present in anterior section, absent in posterior section ( Fig. 2C View Fig ). Area superomedia indistinct. Propodeal spiracle slightly elongate. Area basalis trapezoidal, widened anteriorly. Fore wing length 8.3–8.8 (HT: 8.8) mm. Areolet pentagonal, vein 2rs-m and vein 3rs-m subparallel ( Fig. 5C View Fig ). Nervellus of hind wing intercepted below the middle by second abscissa of vein Cu ( Fig. 5C View Fig ). Hind coxa with an antero-basal weak convexity. Hind femur 6.1–6.6 (HT: 6.1) × as long as maximum depth in lateral view. Hind TS I: II: III: IV: V = 4.0: 2.0: 1.4: 0.7–0.75 (HT: 0.75): 1.0.
Metasoma. T I 2.6–2.9 (HT: 2.6) × as long as maximum width, largely smooth basally, densely and finely punctate posteriorly, with a pair of strong convexities at base of spiracle, without latero-median carina, with dorso-lateral carina but largely absent, without a pair of triangular convexities at base ( Fig. 2D View Fig ). T II 0.82–0.9 (HT: 0.82) × as long as maximum width. T II, T III and T IV densely and finely punctate. Ovipositor sheath 1.0 × as long as hind tibia. Apex of ovipositor as Fig. 3B View Fig .
Colouration ( Figs 5 View Fig A-G). Body (excluding wings and legs) black to blackish brown, except for: base of FL I tinged with reddish brown; FL VI to FL VI whitish yellow except for outer surface; Posterior margin of T VI and T VII with a white membranous area; ovipositor reddish brown. Wings hyaline. Veins and pterostigma blackish brown to brown except for yellowish brown wing base. Legs black to blackish brown.
Male (n=1). Similar to female ( Figs 5H, I View Fig ). Body length 10. 2 mm. Face 0.45 × as long as maximum wide. OD: POL: OOL = 1.0: 1.75: 1.75. Flagellum with tyloid from FL 12 to FL 21. FL I 2.85 × as long as maximum depth in lateral view. Fore wing 7.5 mm. Hind femur 6.35 × as long as maximum depth in lateral view. T I 3.5 × as long as maximum width. T II 0.9 × as long as maximum width. Antenna without a white area. Scutellum with a small yellow spot. Posterior margin of metasomal tergites more or less tinged with yellowish brown. Base of hind femur narrowly tinged with reddish brown.
Distribution. Japan (Honshu).
Etymology. The epithet is from the type locality, Nippon (= Japan).
Remarks. This species resembles B. melana Sheng & Sun, 2014 (male unknown) in the coloration of body and legs, the sculptured speculum and the shape of vein AP of hind wing, but it can be distinguished by the antenna of female with a white band (without it in B. melana ) and the area superomedia indistinct (distinct in B. melana ). This species can easily be separable from B. laborator by the black legs (red in B. laborator ).
