Description. Female (n = 1). Body polished; covered with setae; body length 7.4 mm.

Head 0.57 × as long as wide in dorsal view. Clypeus 1.9 × as wide as long; slightly convex in lateral view; sparsely punctate; lower margin subtruncate; sharp in lateral view. Face 0.4 × as long as minimum width; matt; slightly convex medially; densely punctate medially. Anterior tentorial pit small. Frons slightly concave above antennal sockets; finely and densely punctate dorsally. POL 1.25 × as OD. OOL 1.0 × as OD. Gena and vertex finely and densely punctate. Dorsal profile of gena slightly convex; width abruptly narrowing posteriorly ( Fig. 35D). Occipital carina complete. Malar space 1.4 × as long as basal width of mandible. Mandible flat at base; lower tooth equal in length of upper tooth. Antenna with 24 flagellomeres; not flattened and tapped. FL I 4.2 × as long as maximum depth in lateral view, 1.05 × as long as FL II.

Mesosoma. Pronotum rugulose ventrally; finely punctate dorsally ( Fig. 35E). Epomia long; dorsal end situated between collar and dorsal margin of pronotum. Mesoscutum densely and finely punctate. Notaulus sharp ( Fig. 35D); posterior end reaching centre of mesoscutum. Scutellum densely punctate; convex in lateral view. Mesopleuron punctate dorsally, irregularly rugulose ventrally; with conspicuous smooth area around speculum. Epicnemial carina present laterally and ventrally. Sternaulus deep in anterior 0.6 of mesopleuron. Metapleuron rugose to rugulose; with complete juxtacoxal carina. Propodeum punctate anteriorly; rugose or rugulose posteriorly; with all carinae except for anterior transverse carina absent; area superomedia defined ( Fig. 35G), longer than maximum width; apophysis absent; spiracle oval. Fore wing length 5.4 mm. Areolet as long as maximum width; width not narrowing anteriorly; received vein 2m-cu at near middle ( Fig. 35F). Fore wing vein 1cu-a slightly antefurcal to vein M&RS. Nervellus subvertical; intercepted near posterior end of vein. Hind femur reticulate coriaceous; 4.6 × as long as maximum depth in lateral view. Tarsal claws simple.

Metasoma matt. T I 1.85 × as long as maximum width; postpetiole partly irregularly rugulose ( Fig. 35H); lateromedian carina absent; dorso-lateral carina complete. T II 0.8 × as long as maximum width; largely matt ( Fig. 35H); thyridium indistinct. T III to T V coriaceous and finely punctate anteriorly, smooth posteriorly. Ovipositor sheath 1.43 × as long as hind tibia, 2.7 × as long as T I. Ovipositor straight; apex sharp; apex of lower valve with teeth ( Fig. 79F).

Colouration ( Figs. 35A–H). Body (excluding wings) black to blackish-brown. Setae silver. Subapical part of mandible, labrum, and posterior margin of T II tinged with reddish-brown. FL VI to FL X with white markings. Wing base, base of hind tibia, tibial spurs of all legs, and apex of metasoma ivory. Trochantelli paler than other parts of each leg. Ovipositor reddish-brown. Wings hyaline. Veins and pterostigma blackish-brown to brown except for ivory wing base.

Male. No additional specimen available. Malar space 1.0 × as long as basal width of mandible. Antenna with 27 flagellomeres. T I 2.3 × as long as maximum width. FL I slightly longer than FL II. Face with pair of large yellow markings laterally. Clypeus yellow. Ventral surface of scape and mandible except teeth both largely yellow. Fore and mid trochanter and trochantelli ivory. Base of tibiae ivory.

Distribution. Japan (Amamioshima Is. and Tokunoshima Is.).

Bionomics. Unknown.

Remarks. Momoi (1970) described the female of this species briefly. I could not find the voucher specimen of this species in MNHAH. The following two character states of KPM-NK 102806 described above are largely differed from the description by Momoi (1970): T I 1.85 × as long as maximum width (1.5 × as long as wide at apex in Momoi’s description); ovipositor sheath 2.7 × as long as T I (about 2.0 × in Momoi’s description). These may be the intraspecific variation of this species.
