A phylogenetic reassessment of the Sceloporus torquatus species complex is presented using a multilocus approach. Topological conflicts related to a clade belonging to disjunct southern populations of S. madrensis are resolved, confirming the identity of such populations as distinct from the nominal populations of S. madrensis located 175 kilometres to the north. We describe this southern clade as a new species distributed in the Sierra Madre Oriental based on its phylogenetic distinctiveness and a combination of morphological characters and measurements, increasing the number of recognised species in the S. torquatus complex to seven.
