Diagnosis

Workers Dimorphic. The minor workers very small; the major workers with massive heads and more larger than workers. Antennae 11-segmented (11 to 9, rarely 8-segmented in Old World species) with club 2-segmented. Mandibles with 4 or 5 teeth. Eyes present in majors, reduced in minor workers. Metanotal groove well developed. Propodeum armed with teeth, triangles or angulations. Queens. Strongly larger than workers. Antennae 10-segmented, the apical segments thicker than basal segments. Palps 3,2. Basal segment of the maxillary palp elongated laterally. Mandibles with 4-6 teeth. Propodeum armed. Postpetiole very broadly attached to the gaster. Males (Ettershank 1966): “Genitalia not fully retractile, about half exserted; parameres small, tips setose; aedeagus flattened, deep, ventrally dentate; digit rod-like, tips hooked, heavily sclerotized”.
