Description.

♀, length of body in lateral view 3.9 mm, length of antenna 4.0 mm and of fore wing 3.5 mm.

Colour: Body (Fig. 3A ) black, but metasoma entirely pale yellow; antenna dark brown basally, apical parts pale yellow (two apical segments missing); hind leg basally tri-coloured, coxa pale yellow, apical part of hind femur and hind tibia yellowish brown, posterior part of hind femur, hind tibia and hind tarsus reddish brown.

Head (Fig. 3D ): Width of head 2.1 times its median length in dorsal view. Antenna incomplete, remaining part as long as body and 29 segmented. First flagellomere 1.4 times longer than second and 4.4 times longer than wide. Compounded eye slightly oval, in lateral view 1.2 times as long as wide. Minimum width of face (Fig. 3E ) 1.8 times its height (measured from ventral rim of antennal sockets to upper margin of clypeus); face granulate and with long setae; labrum wrinkled. Eye in dorsal view 2.4 times as long as temple. Ocello-ocular line (OOL) 5.4 times longer than diameter of anterior ocellus; OOL: antero-posterior ocellar line (AOL): postero-ocellar line (POL) = 22: 5: 7. Vertex with long setae. Mandible 1.6 times longer than wide, first tooth with setae; first tooth lobe-shaped; second tooth reddish brown, narrow and sharp; second tooth 1.5 times longer than first tooth; apical part of third tooth reddish brown, short and flat. Maxillary palp pale yellow and 0.8 times longer than mesosoma.

Mesosoma: In dorsal view mesosoma 1.9 times longer than wide, 1.4 times longer than wide in lateral view. Mesoscutum (Fig. 3G ) with slightly oval medio-posterior depression and long setae; notauli impressed anteriorly, not reaching medio-posterior depression; mesosoma crenulated anteriorly; scutellar sulcus with four carinae; in lateral view, apical part of mesopleuron and metapleuron with long setae. Metanotum rugose. Propodeum (Fig. 3G ) entirely rugose, 0.4 times longer than wide in maximum length; precoxal sulcus (Fig. 3F ) distinct, apical part with setae, occupying entire length of mesopleuron; propodeum curved dorsally in lateral view. Fore wing (Fig. 3C ) 2.2 times as long as wide in maximum length; pterostigma 3.3 times as long as wide; vein r of fore wing 3.6 times longer than wide; vein 2-SR slightly bent; vein 2-SR+M and r-m not sclerotized; 2-SR: r: 3-SR = 10: 2: 7; first discal cell of fore wing approx. 0.9 times longer than wide in median length; first subdiscal cell of fore wing approx. 4.1 times longer than wide medially. Hind wing vein M+CU: vein 1r-m = 16: 5.

Leg: Hind coxa apically pale yellow; hind coxa 1.2 times longer than hind trochanter; hind femur 4.6 times as long as wide and 0.7 times longer than hind tibia; hind tibia as long as hind tarsus.

Metasoma: First tergite striate and narrow, 2.5 times longer than its apical width and dark brown. Setose part of ovipositor sheath (Fig. 3I ) 1.3 times longer than mesosoma and 1.3 times longer than hind tibia.

Male. Unknown.

Distribution.

Eastern Palaearctic, Japan, Russia ( Yu et al. 2016), South Korea (new record).
