title: Two newLiolaemuslizards from the Andean highlands of Southern Chile (Squamata, Iguania, Liolaemidae).
abstract: Liolaemusis a diverse genus of lizards, subdivided into two subgenera:Liolaemus(sensu stricto) andEulaemus, distributed mainly in Chile and Argentina. TheLiolaemus elongatus-kriegicomplex is the most diverse group withinLiolaemus(sensu stricto), especially the species closely related toLiolaemus elongatus, which form a clade currently comprising nine species. Several Chilean species of this group have been recently described, mainly from volcanoes and poorly explored mountains. Here molecular and morphological evidence are provided for a new species of theLiolaemus elongatusclade, which is characterized by its small size and lack of dorsal pattern, unusual features for the species of this group of lizards. Additionally, the lack of precloacal pores in males ofLiolaemus(sensu stricto) is a trait found in few species, which do not constitute a monophyletic group. A second new southern Chilean species is also described, without precloacal pores and supported by molecular phylogenetics to be related toLiolaemus villaricensis. Both new species were found in the same locality, near a lake located in a pre-Andean zone withAraucariaandNothofagusforest. The two species are dedicated to prominent Lonkos (tribal chiefs) of the Mapuche and Pehuenche people: Janequeo and Leftraru. Additionally, the phylogenetic results suggest thatLiolaemus lonquimayensisis a synonym ofLiolaemus elongatus.
