Mesoscutum with strong reticulation, meshes isodiametric on sidelobes, elongate on midlobe; midlobe without median groove, with seven scattered adnotaular setae. Mesoscutellum with strong reticulation, meshes isodiametric in posterior half, elongate in anterior half; submedian grooves indistinct and partly absent, slightly curved and diverging towards posterior part; with a ±complete median groove; frenal groove wide and subdivided by carinae; with an expanded and strongly reticulate part behind frenal groove. Dorsellum with strong reticulation. Propodeum with a strong and relatively wide median carina that expands posteriorly; callus with six setae. Fore and hind coxae with strong reticulation, mid coxa with weak reticulation; hind coxa with a carina along posterior margin. Fore wing with five setae on dorsal surface of submarginal vein; speculum open.
