Gena and mesopleuron more or less smooth, distinctly punctate ( Fig. 44 ). Clypeus large, lenticular. Malar space 0.7–0.9× as long as basal mandibular width ( Fig. 44 ).Antennal flagellum tapered towards apex. Notaulus distinct, with irregular wrinkles ( Fig. 44 ). Foveate groove of mesopleuron deep and long, distinctly upcurved anteriorly, with transverse wrinkles ( Fig. 45 ). Propodeal spiracle moderately large, separated from pleural carina by 1.5–2.0× diameter of spiracle ( Figs 44, 45 ). First tergite smooth laterally and dorsally ( Figs 44, 46 ); postpetiole in dorsal view much wider than petiole; glymma large, joining by distinct furrow to ventral part of postpetiole ( Figs 44, 46 ).
