Description. Female (n=2). Body length 4.2–4.9 (HT: 4.9) mm. Body polished, covered with silver setae.
Head. Clypeus 2.0 times as wide as maximum length, sparsely punctate, its anterior margin weakly rounded. Face densely punctate, with a median weak convexity. MSL 1.15–1.2 (HT: 1.2) times as long as BWM. Frons sparsely punctate, with transverse rugae just above antennal sockets, with a median longitudinal groove. Gena punctate. Vertex sparsely punctate anteriorly, punctate posteriorly, with a median longitudinal groove ( Fig. 19D View Fig ). OOL slightly shorter than POL and as long as OD ( Fig. 19D View Fig ). Occipital carina complete, its lower end joined with hypostomal carina distant from mandibular base by the length of BWM. Upper tooth of mandible longer than lower tooth. Base of mandible slightly convex. Antenna with 20–21 (HT: 21) flagellomeres. FL I, FL II, and FL III almost equal in length. FL III 6.7–7.0 (HT: 6.7) times as long as maximum depth in lateral view. Apex of flagellum more or less pointed.
Mesosoma 1.75 times as long as maximum depth in lateral view. Upper side of collar with a median carina. Lateral part of pronotum largely smooth dorsally, largely striate ventrally. Epomia short and weak. Mesoscutum largely smooth, with a median longitudinal groove on the median lobe ( Figs 19E View Fig , 63G View Fig ). Notaulus long, its posterior ends joined with each other posteriorly ( Figs 19E View Fig , 63G View Fig ). Scutellum smooth except for a few punctures, without a lateral longitudinal carina except for base. Postscutellum smooth. Mesopleuron densely punctate except for areas above and below smooth speculum with longitudinal striae. The impression that is just below speculum with an isolate pit. Posterior transverse carina of mesosternum complete. Metapleuron densely punctate, with a complete juxtacoxal carina. Anterior and posterior transverse carinae of propodeum complete. Pleural carina complete. Basal section of lateral longitudinal carina of propodeum absent. Area basalis distinct ( Fig. 65E View Fig ). Area superomedia more or less indistinct laterally ( Fig. 65E View Fig ). Propodeum largely rugose-punctate. Propodeum without projections. Length of fore wing 3.6–4.2 (HT: 4.2) mm. Areolet absent ( Fig. 19F View Fig ). Vein 2m-cu of fore wing with two bullae ( Fig. 19F View Fig ). Nervellus inclivous, intercepted slightly posterior to middle ( Fig. 19G View Fig ). Hind femur 4.9 (HT: 4.9) times as long as maximum depth in lateral view. Hind TS I: II: III: IV: V = 2.0: 0.8: 0.6: 0.35: 0.6. Tarsal claws simple.
Metasoma. T I 1.25–1.4 (HT: 1.25) times as long as maximum width, largely longitudinally striated except for smooth posterior margin ( Fig. 19H View Fig ), the interspace of striae punctate. Median dorsal carina of T I indistinct. Dorsolateral carina of T I complete. T II to T VI wider than long. T II and T III densely punctate and longitudinally striated except for smooth posterior area ( Fig. 19H View Fig ). Laterotergite of T II separated from T II. T IV to T VII largely smooth, with fine and sparse punctures. Ovipositor sheath 0.5–0.58 (HT: 0.5) times as long as hind tibia. Ovipositor straight, with a weak nodus and ventral teeth ( Fig. 66D View Fig ).
Coloration ( Figs 19A–H View Fig ). Head yellow. Apex of mandible, dorso-median part of face, area above antennal sockets, and antenna more or less tinged with reddish brown. Oceller area, posterior and median parts of vertex, and postero-dorsal part of gena blackish brown. Mesosoma yellow. Latero-median part of pronotum reddish brown. Propleuron tinged with reddish brown. Mesopleuron with three reddish brown stripes, its posterior part relatively darkened than anteriorly. Scuto-scutellar groove blackish brown to black. Axillae black. Scutellum with a median brown spot. Mesopleuron with reddish brown areas below subtegular ridge and speculum. Metapleuron with blackish brown margins. Dorsal face of propodeum largely blackish brown to black. Area petiolaris with a median blackish brown to black area. Metasoma blackish brown to black. Posterior margins of T I to T V broadly yellow. Posterior margins of T VI and T VII narrowly yellow. Border of black and yellow areas tinged with reddish brown. Lateral part of T II to VII reddish brown to yellow. Membranous part of metasomal sternites yellow. Ovipositor reddish brown. Wings hyaline. Veins and pterostigma yellowish brown. Legs yellowish brown. Coxae, trochanters, trochantelli, and base of hind tibia whitish yellow except for ventral face of hind coxa reddish brown. Reddish brown areas of pronotum and mesopleuron darkened in paratype.
Male. Unknown.
Distribution. Japan (Tokunoshima Is. and Ishigakijima Is.).
Bionomics. Unknown.
Remarks. This species can be distinguished from other species by the following combination of character states: body length 4.2–4.9 mm (7.0 mm in Be. striata ); median lobe of mesoscutum with a conspicuous median groove (without a median groove in Be. testacea); hind coxa without a black area (with a black area in Be. striata ); mesosoma and metasoma with conspicuous reddish brown and black areas (almost entirely reddish brown in Be. taiwanella); fore wing without a clouded band (with a clouded band in Be. taiwanella); head with black area (without black area in Be. divisa).
