Establishing the ancestral area of a group of organisms is one of the central objectives of historical biogeography. I applied three methods of ancestral area analysis, Fitch optimization, weighted ancestral area analysis and dispersal‐vicariance analysis (DIVA) to establish the ancestral area of the iguanian lizard genus Phymaturus . I then extended the analysis to hypothesize the ancestral area for Liolaemidae ( Ctenoblepharys , Liolaemus and Phymaturus ). The ancestral area for Phymaturus is Patagonia Central or Patagonia Central‐Cordillera Andina and Valle Central. For Liolaemidae, the ancestral area is Patagonia Central‐Coastal Perú, or Patagonia Central‐Patagonia Occidental‐Cordillera Andina and Valle Central‐Coastal Perú. The ancestral area of Phymaturus is congruent with previous studies, but the inclusion of Ctenoblepharys poses some questions regarding the distribution of the ancestor of the family.
