Genus Polyergus Latreille, 1805

Polyergus Latreille, 1805: 256. Type-species: Formica rufescens Latreille, 1798.

This genus includes three palaearctic and several nearctic species immediate recognisable from other formicine ants by the long sickle shaped toothless mandible and much reduced thin palps, formula 4: 2. Members of this genus raid nests of ants the Formica fusca group to carry away pupae to be reared as auxiliaries in the ho[[..]] nest. Polyergus workers are unable to feed themselves and are entirely dependent o captive Formica for their survival.
