Ocello-ocular line ( OOL) 4.9 × longer than diameter of anterior ocellus; OOL: antero-posterior ocellar line ( AOL): postero-ocellar line ( POL) = 28: 7: 9. Vertex smooth and glabrous, longitudinal groove present POL. Width of clypeus 2.6 × its maximum length. Mandible (Fig. 5 L ) 1.2 × longer than wide, wide with first tooth curved upward and broad; second tooth narrow and long, 1.2 × longer than first tooth, tip of second tooth dark brown; first and second tooth distinctly separate; third tooth as long as first tooth.

Mesosoma: In dorsal view mesosoma 2.0 × longer than wide and 1.4 × longer than high in lateral view. Mesoscutum (Fig. 5 F ) with small and round medio-posterior depression and glabrous; notauli distinct anteriorly to half of mesoscutum, not reaching to medio-posterior depression; anterior part of mesoscutum with few setae; scutellar sulcus with one carina; apical part of mesopleuron and metapleuron with few setae, mesopleuron groove sculptured in lateral view. Precoxal sulcus distinct, not reaching anterior and posterior edge of mesopleuron. Maximum length of propodeum (Fig. 5 F ) 0.5 × its width; longitudinal carina present on propodeum, posterior part of propodeum with small areola, not reaching up to half of propodeum, anterior part of propodeum smooth. In lateral view, metanotum curved medio-dorsally (Fig. 5 G ). Fore wing (Fig. 5 C ) 2.3 × as long as wide; pterostigma widened medially and nearly as wide as vein 1 - R 1; vein r of fore wing 3.8 × longer than wide; vein SR 1 3.0 × longer than vein 3 - SR; vein 3 - SR 1.8 × longer than 2 - SR; second submarginal cell 2.4 × longer than its medium length; 3 - SR: r: SR 1 = 5: 1: 15; first discal cell of fore wing as long as wide medially. Hind wing: vein M + CU + 1 - M: vein 1 r-m = 4: 1.
