Holotype, female, length of body 9.8 mm, of fore wing 5.8 mm, and of ovipositor sheath 10.2 mm.
Head. Antenna with flagellomeres partly missing; frons transversely striate-rugose (Fig. 344); three anterior coronal teeth acute, both posterior ones wide and arcuate; sculpture on vertex varied from rugose to striate-rugose (Fig. 342); temple smooth and shiny (Fig. 343), distinctly roundedly convex behind eyes.
Mesosoma. Pronotum (Figs 339, 340) robust, dorsally largely coarsely carinate or striate and laterally rugulose; neck short and transversely impressed posteriorly; pronotal fold and concavity absent; middle pronotum gradually elevated connected with posterior pronotum; mesoscutum anteriorly microreticulate and posteriorly foveolate; notauli and median groove distinct and formed by foveolae; scutellum (Fig. 341) coarsely coriaceous and laterally with several foveolae; mesopleuron robust, irregularly with dense and shallow foveolae; convex part of metapleuron coarsely reticulate-rugose; propodeum densely and coarsely foveolate (Fig. 341).
Wings. Fore wing (Fig. 338): vein 1-M 2.2 times as long as vein 1-SR and 1.3 times vein m-cu; vein cu-a slightly antifurcal and subvertical; vein 2-SR 2.6 times as long as vein r; vein r ends 0.3 times length of pterostigma behind level of apex of pterostigma; vein r and vein 1-M distinctly curved; vein 1-SR slightly shorter than parastigmal vein; vein 3-CU1 basal 0.2 tubular, remainder largely nebulous, apically distinctly curved.
Legs. Hind coxa rugose, but rugae on posterior third more regular and somewhat transverse (Figs 345, 346); hind femur densely finely aciculate, ventrally with two large obtuse teeth and some denticles in between (Figs 348, 349); hind tibia about 1.2 times as long as hind femur, basal narrow part 1.3 times as long as widened part, narrow part of inner side coriaceous (Fig. 349), widened part of inner side distinctly depressed basally and densely bristly setose apically; basitarsus rather robust, ventral length about 4.2 times as long as its apical width.
Metasoma. First tergite densely transversely striate, 4.2 times as long as its maximum width, 2.2 times second tergite and 0.9 times remainder of tergites; basal 0.2 of second tergite with weak rugae, remainder of tergite smooth or indistinctly microreticulate; pygidial impression indistinct (Fig. 347); ovipositor sheath (Fig. 350) about same size as body.
Colour. Largely blackish; frons largely orange-brown; temple and hind tibia completely yellowish; second tergite basally reddish.
