Figure 6

From the left to right: Phylogenetic relationship among Acromyrmex striatus, Acromyrmex spp. and Atta ssp. showing A. striatus as a sister group of the reminder leafcutter ants. Ideograms representing the haploid chromosome complement know for each cluster, Atta ssp. and A. striatus shared the haploid number of 11 chromossomes and the majority of metacentric chromosomes. Morphological characters (from description by Mayhé-Nunes [7]) shared among A. striatus, Atta spp. and Acromyrmex spp., three pairs of spines on promesonotum are beard by A. striatus and Acromyrmex spp, while Atta spp. display two pairs of spines, on the other hand A. striatus and Atta spp. display smooth gastral tergum whereas Acromyrmex spp. has a tuberculate gaster.
