Mesoscutellum with strong reticulation, meshes distinctly elongate; submedian grooves weak but traceable, wide apart, straight and diverging towards posterior part; anterior pair of setae placed in anterior one-third. Dorsellum with strong reticulation. Propodeum with median carina wide and strongly expanding in posterior part, anterior part not raised; callus with two setae. Fore and hind coxae with strong reticulation, mid coxa with weak reticulation, hind coxa without carina along posterior margin.
