Abstract

The genus Psammodromus (Lacertidae) comprises six species. Three of the species are morphologically similar, phylogenetically closely related, and are distributed in the Iberian Peninsula (besides P. algirus): P. occidentalis (Western Iberia), P. hispanicus (Central Spain), and P. edwarsianus (Eastern Spain). Previous studies have shown these three species to have allopatric distributions in Iberia, though there are still many areas such as Andalucía where it is unclear which species of Psammodromus occurs. In this study we present nine new records of Psammodromus from key places in southern Spain. Since the three Iberian species are difficult to differentiate by morphology, specimens were genetically identified using mitochondrial DNA data and compared to all six species of the genus. Here we present an updated distribution map of Psammodromus specimens identified with molecular methods, increasing the ranges of all three species. We also propose wider regions of potential sympatry between P. occidentalis and P. hispanicus, and P. edwarsianus and P. hispanicus than previously recorded.
