The South American Tropidurid lizard Stenocercus marmoratus: Redescription, Distribution, and Natural History

The holotype of Stenocercus marmoratus is redescribed, and morphological variation is documented for this poorly known tropidurid lizard. Stenocercus marmoratus has a more extensive distribution than previously thought and inhabits subhumid habitats of the Andes from Cochabamba, Bolivia to northernmost Argentina. Dumeril and Bibron are the authors of the name marmoratus and not D\u27Orbigny as believed by some revisors of this species. A key to the genus Stenocercus in Bolivia and Argentina is provided
