| Profile of alitrunk not continuous and evenly convex, the propodeum distinctly depressed below the level of the mesonotum, meso-epinotal suture always distinct, often deep (Figs. 30, 31); antennae inserted at or near the dorsal border of the clypeus (Fig. 32); metapleuron with a distinct, wide orifice for the metapleural gland, the orifice situated above the hind coxa and below the level of the propodeal spiracle.
