More cryptic diversity among spiny lizards of the <i>Sceloporus torquatus</i> complex discovered through a multilocus approach

<p dir="ltr">A phylogenetic reassessment of the <i>Sceloporus torquatus</i> species complex is presented using a multilocus approach. Topological conflicts related to a clade belonging to disjunct southern populations of <i>S. madrensis</i> are resolved, confirming the identity of such populations as distinct from the nominal populations of <i>S. madrensis</i> 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 <i>S. torquatus</i> complex to seven.</p>
