The Liolaemus montanus group is distributed over a wide latitudinal and altitudinalgeographic range from central Perú to central Argentina and Chile, and from sea level to more than 5000 masl. A comprehensive hypothesis of phylogenetic relationships islacking and species in this group are arranged based on overall morphological featuresthat preclude further evolutionary studies. We present the first comprehensivemolecular phylogenetic hypothesis for this group based on a sample of 33 knownspecies (of about 60 species assigned to this group), and four genes (two mitochondrial and two nuclear regions). Our results show that the L. montanus group is not monophyletic and some species that were previously included in this group, seem to be part of other species arrangements in the same subgenus. We discuss taxonomic andbiogeographic implications of our results.
