Revision of the minuta-group of the genus Gnamptogenys (Hymenoptera, Formicidae)

Abstract

The Neotropical minuta group of Gnamptogenys Roger is revised. A group synopsis for the workers is given, as well as a comparative table of characters that separate the group from the rest of Gnamptogenys. The possible evolutionary history of the nine species of the group is discussed. An identification key is included, and information for each species is reviewed.
