The objective of this work is to present a detailed phylogeographic analysis of one of the most conspicuous group of lizards distributed in northwestern Patagonia, the Liolaemus kriegi complex.This region is geographically very complex due to Andean orogeny and subsequent volcanism coupled with a long history of glaciations that produced pronounced climatic changes over the last million years (Myr). For 247 individuals we sequence one mitochondrial gene (cytochrome-b) and for a subset we sequenced another mitochondrial gene 12S rRNA (12S) and two nuclear fragments: kinesin family member 24 (KIF24) and BA3 rRNA (BA3). We obtained gene trees and mitochondrial and nuclear haploytpe networks, and estimated genetic distances between main lineages and basic molecular diversity indices. We also performed Spatial Analysis of Molecular Variance (SAMOVA) and Bayesian Skyline Plot (BSP) analyses. All of our analyses, except for the two nuclear haplotype networks, provided concordant results in recognizing seven lineages: two described species,
