Diagnostic Notes

Monomorphic or exhibit continuous size polymorphism, but there is no distinct major worker caste; mandibles with 4 or 5 teeth; antennae 11-segmented (with the exception of one lineage of Asian and African species, in which there are 10 segments); enlarged apically (club of 2–4 segments); propodeum usually armed with a pair of dorsal spines; petiole low and rounded and lacks a node on its upper surface; when the gaster is elevated the petiole fits flush against the propodeum; postpetiole attached to the anterior dorsal surface of the first gastral segment. In profile, dorsum of gaster flat, feebly convex or concave. This contrasts with the strongly convex ventral surface. In dorsal view, the gaster is heart-shaped.
