Mesoscutellum with strong reticulation, meshes elongate; submedian grooves indistinct but traceable, wide apart, slightly curved and diverging towards posterior part; anterior pair of setae in median part of mesoscutellum. Dorsellum with strong sculpture, hidden under mesoscutellum and not visible in dorsal view. Propodeum with a strong median carina that splits in posterior part, forming an inverted “Y”; callus with two setae. Fore and hind coxae with strong reticulation, mid coxa with weak reticulation, fore coxa with a sharp edge along posterior margin, hind coxa without carina along posterior margin.
