Taxonomic History (provided by Barry Bolton, 2015)
Extant: 1 tribe, 3 genera, 230 species, 36 subspecies
Fossil: 19 species
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; scape relatively short (SL/HL < 0.75); clypeus narrow (front to back) and not extending posteriorly between the frontal carinae; metapleural gland orifice situated at extreme posteroventral margin of metapleuron; hind tibia usually with two apical spurs, of which the posterior spur is pectinate; and sting well developed.
These are slender, large-eyed arboreal ants, predominantly tropical or subtropical in distribution. One genus and two species occur in California.
