Resumen:
The Liolaemus alticolor-bibronii group is distributed over a wide latitudinal geographic range, from central Perú to Argentina and includes 30 described species and 8 candidate species. Current hypotheses of phylogenetic relationships are mostly based on morphological evidence, but lack of resolution and statistical support preclude these hypotheses to be used for further evolutionary studies. We present the first comprehensive molecular phylogenic hypotheses for this group based on 2 mitochondrial and 4 nuclear regions. Our results show that the Liolaemus alticolor-bibronii group is not monophyletic and some species of this group are more closely related to other species of the subgenus Liolaemus. We inferred a strongly monophyletic group that we call the walkeri clade, composed of L. chavin, L. pachacutec, L. tacnae, L. walkeri and L. wari. These results are in agreement with a previous mitochondrial molecular study that also inferred this group as a clade. We discuss taxonomic and biogeographic implications of our systematic results.
