Mesoscutum with strong reticulation, meshes isodiametric on sidelobes, elongate on midlobe, midlobe without a median groove, with nine scattered adnotaular setae. Mesoscutellum with weak reticulation on median part and with a weak a median groove in anterior two-thirds, lateral parts with strong reticulation, meshes elongate; submedian grooves indistinct, running close to and parallel with lateral margin of mesoscutellum; anterior pair of setae situated in anterior part. Dorsellum with strong sculpture. Propodeum with strong reticulation; with a strong and wide median carina that expands strongly backwards from median part; callus with eight setae. Fore and hind coxae with strong reticulation, mid coxa with weak reticulation; hind coxa with a carina along posterior margin.
