Redescription.

♀, length of body in lateral view 3.4 mm, length of antenna 4.0 mm and of fore wing 4.1 mm.

Colour: Body (Fig. 2A ) black, but metasoma entirely reddish brown; antenna dark brown basally, leg yellowish brown basally, tarsus brown.

Head (Fig. 2D ): Width of head 2.0 times its median length in dorsal view. Antenna 1.2 times longer than body, 38 segmented. First flagellomere 1.2 times longer than second and 3.8 times longer than wide. Compounded eye slightly oval, in lateral view 1.4 times as long as wide. Minimum width of face (Fig. 2E ) 1.8 times its height (measured from ventral rim of antennal sockets to upper margin of clypeus); face wrinkled with long setae. Eye in dorsal view 1.3 times as long as temple. Ocello-ocular line (OOL) 6.1 times longer than diameter of anterior ocellus; OOL: antero-posterior ocellar line (AOL): postero-ocellar line (POL) = 23: 6: 7. Vertex smooth and with sparse long setae. Mandible 1.4 times longer than wide, with three teeth; first tooth lobe-shaped; second tooth reddish brown, wide and sculptured; second tooth 1.3 times longer than first tooth. Maxillary palp pale yellow and 0.5 times longer than mesosoma.

Mesosoma: In dorsal view mesosoma 2.0 times longer than wide, 1.6 times longer than wide in lateral view. Mesoscutum (Fig. 2G ) with oval medio-posterior depression and long setae; notauli impressed anteriorly, not reaching medio-posterior depression; anteriorly mesosoma crenulated widely; scutellar sulcus with four carinae; in lateral view, mesopleuron and metapleuron with long setae. Metanotum sculptured. Propodeum (Fig. 2G ) entirely wrinkled, 0.5 times longer than wide in maximum length; precoxal sulcus (Fig. 2F ) distinct, without setae, occupying entire length of mesopleuron; propodeum curved dorsally in lateral view. Fore wing (Fig. 2C ) 2.2 times as long as wide in maximum length; pterostigma 3.4 times as long as wide; vein r of fore wing 2.1 times longer than wide; vein 2-SR slightly bent; vein 2-SR+M and r-m not sclerotized; 2-SR: r: 3-SR = 6: 1: 5; first discal cell of fore wing approx. 0.8 times longer than wide in median length; first subdiscal cell of fore wing approx. 3.6 times as long as wide in median length. Hind wing vein M+CU: vein 1r-m = 4: 1.

Leg: Hind coxa apically pale yellow and 1.2 times longer than hind trochanter; hind femur 4.4 times as long as wide and 0.7 times longer than hind tibia; hind tibia 1.2 times longer than hind tarsus.

Metasoma: First tergite striate and narrow, 1.7 times longer than its apical width and dark brown. Setose part of ovipositor sheath (Fig. 2I ) 1.2 times longer than mesosoma and 1.2 times longer than hind tibia.

Male. Unknown.
