Workers of this subfamily can be recognized by the combination of large eyes (EL/HL usually > 0.25), short mandibles, flexible promesonotal connection, and presence of a postpetiole. Other characteristic features include: antennal sockets partly exposed in full-face (frontal) view; the scape is relatively short (SL/HL < 0.75); the clypeus is narrow (front to back) and does not extend posteriorly between the frontal carinae; the metapleural gland orifice is situated at the extreme posteroventral margin of the metapleuron; the hind tibia usually has two apical spurs, of which the posterior spur is pectinate; and the sting is well developed.
