The Bayesian phylogeny of South American Rhinella toads with a focus on the Rhinella margaritifera group and closely related species. Numbers below the branches correspond to the Bayesian posterior probabilities and ML bootstrap values. Nodes were collapsed if appeared in less than 50% of the post burn-in tree samples. In red the three toad species collected in the Cordillera Yanachaga mountains, Selva Central, Peru, representing members of three different species groups.
