Molecular phylogenetic reconstruction and localization of the (TTAGG)n telomeric repeats in the chromosomes of (Roger, 1863) suggests a lower ancestral karyotype for leafcutter ants (Hymenoptera).

Chromosome counts and karyotype characterization have proved to be important features of a genome. Chromosome changes during the diversification of ants might play an important role, given the diversity and success of Formicidae. Comparative karyotype analyses on ants have enriched and helped ant systematics.
