Whereas it is generally agreed that the Neotropical bat family Mormoopidae, as well as the two mormoopid genera (Mormoops and Pteronotus) are each monophyletic, relationships among the six extant species of Pteronotus remain unresolved. The purpose of this study was to evaluate phylogenetic relationships within Pteronotus using DNA sequence data from the mitochondrial ribosomal and cytochrome b genes and the nuclear Recombination Activating Gene-2 based on likelihood inferential techniques (maximum likelihood and Bayesian phylogenetics). Results of this study present, for the first time, a fully resolved and strongly supported phylogeny for all relationships within Pteronotus. These data strongly support: sister-group relationships between davyi and gymnonotus (subgenus pteronotus), between macleayii and quadridens (subgenus chilonycteris), and between the subgenera pteronotus and chilonycteris. Pteronotus personatus is sister to this clade and P. parnellii is the most basal lineage of Pteronotus. Although this is the first study to provide a fullyresolved and strongly supported hypothesis for the phylogenetic relationships among species of Pteronotus, future work must focus on phylogeographic surveys within each species because previous studies have suggested that parnellii and personatus may contain undescribed species.
