Abstract
The phylogenetic relationships of Sciurus species present in Mesoamerica are addressed using a morphological analysis under Maximum Parsimony. Our results recovered the existence of two clades: one comprising S. aureogaster, S. colliaei, S. variegatoides and Syntheosciurus brochus and the other clade composed by S. richmondi, S. granatensis, S. deppei, S. yucatanensis and Microsciurus alfari. The taxonomic status of the genera Microsciurus and Syntheosciurus is discussed as well the biogeographic implications of these findings.References
