A New Species of Lizard Endemic to Sierra de Fiambala, Northwestern Argentina (Iguania: Liolaemidae: Phymaturus). Integrated Taxonomy Using Morphology and DNA Sequences: Reporting Variation Within the antofagastensis Lineage.

ABSTRACT: The northernmost distributed group of lizards belonging to Phymaturus occurs in rocky outcrops of the Puna region between 3600-4200 m in Argentina. In a recent phylogenetic study based on morphological and genetic information, the monophyly of this small lineage was corroborated. This group is formed by Phymaturus antofagastensis, P. laurenti, P. denotatus, P. mallimaccii and a population of uncertain taxonomic status until the present study. After obtaining new samples and observations, we described a new species belonging to this lineage that is known only from Sierra de Fiambalá, being the species of Phymaturus living at the highest elevation ever recorded (4500 m). Males have a homogeneous yellow dorsum and lack melanic coloration over their he
