Gnamptogenys Roger is a group of predatory ponerine ants found in tropical and subtropical, mesic forested areas in Southeast Asia and Australasia, and from the southern United States to northern Argentina. Most species nest at ground level in rotten wood or leaf litter, but some are arboreal. Their colonies are relatively small, with at most a few hundred workers. Reproduction is generally through queens, though worker reproduction is known in some species from Southeast Asia. While many species are generalist predators, specialized diets such as millipede predation have arisen in several New World lineages. The biology of Old World species is poorly known. The last generic revision recognized 81 species, with 26 Old World species. This book presents a taxonomic revision of the species of Gnamptogenys from the Old World, shows evidence for their monophyly, and assesses their phylogenetic relationships.
