Eleven-segmented antennae; anterior clypeal margin medially impressed; frontal carinae variably developed, ending about halfway between posterior eye margin and posterior head margin, often curving down ventrally and forming posterior margin, and sometimes even ventral margins, of antennal scrobes; anterior face of mesosoma only weakly developed; margination between lateral and dorsal mesosoma weak; propodeal spines short to medium-sized, triangular to elongate-triangular; propodeal lobes triangular and short; petiolar node rectangular nodiform with usually well-defined angles, in profile roughly as high as or weakly higher than long, in dorsal view typically as wide as long, often antero- and posterodorsal angles well-developed and about same height, sometimes anterodorsal angle better developed and higher situated than less angulate, more rounded posterodorsal angle, in the latter case dorsum usually tapering weakly backwards posteriorly; postpetiole usually roughly rounded; mandibles usually sculptured; cephalic sculpturation distinct and predominantly longitudinally rugose; mesosoma and waist segments with distinct sculpturation, postpetiole sometimes with weak sculpturation only; gaster almost always unsculptured, smooth, and shiny; dorsal surfaces of head, mesosoma, waist segments, and first gastral tergite generally with abundant, short to medium-sized, appressed to erect hairs, pilosity on first gastral tergite sometimes reduced; sting appendage spatulate.
