The southwestern Andes of Peru harbor a hidden taxonomic diversity of reptiles. We describe a new species of Liolaemus Wiegmann (Iguania: Liolaemidae) from xerophytic environments of the southwestern slopes of the Andes of Peru, between 2,400– 2,900 m asl. The new species, previously considered as a population of L. insolitus Cei, exhibits unique diagnostic characters of morphological, scalation and color pattern, and molecular evidence, placing the new species in the Liolaemus montanus species group and included in the L. reichei clade. Moreover, the species is endemic to the eastern slopes of La Caldera batholith in the Department of Arequipa, southern Peru. We also provide information on the conservation status of the species and suggest its inclusion in the IUCN red list of the threatened species as endangered (EN). A key for the species of the L. reichei clade is provided.

Key words: Lizards, Taxonomy, Phylogeny, L. insolitus, Arequipa.
