Diagnosis. Head and mesosoma densely granulate, impunctate. Clypeus large, granulate in upper 0.7 ( Fig. 37 ). Malar space about as long as basal mandibular width ( Fig. 38 ). Antenna short, with 17 flagellomeres ( Fig. 39 ); flagellomeres 4 to 7 with distinct subapical finger-shaped structures on outer surface ( Fig. 39 ). Notaulus absent ( Fig. 38 ). Foveate groove of mesopleuron shallow, oblique, with weak transverse wrinkles ( Fig. 38 ). Propodeal spiracle very small, separated from pleural carina by one diameter of spiracle ( Fig. 38 ). Propodeum with basal keel ( Fig. 40 ). First tergite smooth laterally and dorsally ( Figs 38 , 41 ); postpetiole in dorsal view much wider than petiole ( Fig. 41 ); glymma large, joining by distinct furrow to ventral part of postpetiole ( Fig. 38 ). Thyridial depression very short, strongly transverse ( Fig. 41 ). Ovipositor short, weakly upcurved, with weak dorsal subapical depression and more or less distinct rounded tooth before this depression ( Fig. 42 ).
