Phylogenetic tree (ML) inferred using concatenated SSU rRNA and gGAPDH gene sequences of trypanosomes from caimans, crocodiles, tabanids, and tsetse flies. The analyses were inferred by Maximum Likelihood (ML, 1720 characters, Ln = −17593.067085) and Bayesian Inference (BI). Trypanosomes of the crocodilian clade were distributed in the clades Ralphi, Terena, Cay03, Tab01, Kaiowa, and Grayi. Trypanosomes of both terrestrial and aquatic lineages were used as outgroups. Numbers at nodes (ML/BI) are bootstrap support > 50%, and Bayesian posterior probability > 0.8 derived from 500 replicates. Insert: phylogram (ML) using gGAPDH sequences. Numbers at nodes are bootstrap values derived from 500 replicates
