Molecular characterization of fire ants, Solenopsis spp., from Brazil based on analysis of mtDNA gene cytochrome oxidase I.
Bottom Line: The results revealed complete geographical coherence and polyphyly for the Solenopsis invicta Buren and Solenopsis saevissima species groups, which confirms the diversity of the genera.It also suggests the possibility that reproductively-isolated populations occur, resulting in the evolutionary process of speciation.No predominant haplotype was found in the populations analyzed, but some were more prevalent.

Mentions: Of the 726 characters used in maximum parsimony analysis, 482 were constant and 206 were informative characters (parsimonyinformative). Forty-eight equally parsimonious trees were found as a result of phylogenetic analysis of different Solenopsis populations based on a portion of the COI gene. Both analyses (maximum parsimony and Bayesian inference) were nearly the same, and only the Bayesian tree analysis was illustrated with posterior probability values (Figure 3).
