Diagnosis

Apical half of vein 1-M of fore wing dark brown and basal half yellow (Fig. 11F); face granulate-rugose, with median bump (Fig. 11D); mesoscutum and scutellum coarsely rugose (Fig. 11G); pterostigma large (Fig. 11F); apical tooth of mandible rather slender (Fig. 11F); hypopygium apically acute, with up-curved short triangular protuberance (Fig. 11E).
