Among Neotropical ants, the genera Acromyrmex and Atta are of great importance because they include the major agricultural pest species. Regarding the genus Atta, considered one of the most derived of the tribe Attini, cytogenetic data exists for 5 taxa that present 2n = 22 chromosomes; however, information regarding banding patterns is only available for Atta colombica. Cytogenetics has contributed to several aspects related to the family Formicidae, in particular to the understanding of its evolution. Therefore, the aim of this study was to increase the cytogenetic data on Atta sexdens rubropilosa, Atta laevigata and Atta bisphaerica belonging to populations in the state of Minas Gerais, Brazil. The 3 species were characterized as having ...
