A new species of Liolaemus (Reptilia: Squamata) of the Liolaemus capillitas clade (Squamata, Liolaemini, Liolaemus elongatus-kriegi group) from Sierra de Velasco, La Rioja Province, Argentina.

A new species of the Liolaemus capillitas clade is described. Liolaemus galactostictos sp. nov.

New species of (Reptilia, Squamata, Liolaemini) of the clade from northwestern Patagonia, Neuquén province, Argentina.

Two new species of the Liolaemus donosobarrosi clade are described. Liolaemus tirantii sp. nov.

A new lizard species of the Phymaturus patagonicus group (Squamata: Liolaemini) from northern Patagonia, Neuquén, Argentina.

The integrative taxonomy framework allows developing robust hypotheses of species limits based on the integration of results from different data sets and analytical methods. In this work, we test a candidate species hypothesis previously suggested based on molecular data, with geometric and traditional morphometrics analyses (multivariate and univariate). This new lizard species is part of the Phymaturus patagonicus group (payuniae clade) that is distributed in Neuquén and Mendoza provinces (Argentina).

Molecular phylogenetic relationships of the lizard clade Liolaemus elongatus (Iguania: Liolaemini) with the description of a new species from an isolated volcanic peak in northern Patagonia.

A new species of the Andean-Patagonian Liolaemus elongatus clade is described. Liolaemus crandalli sp. nov.

A new lizard of the Phymaturus genus (Squamata: Liolaemidae) from Sierra Grande, northeastern Patagonia, Argentina.

A new species of lizard of the saxicolous and viviparous genus Phymaturus from Patagonia is described. The new species is a member of the Phymaturus patagonicus species group distributed on volcanic plateaus, mountains or rocky outcrops of southern Argentina. Phymaturus yachanana sp.

Molecular phylogenetic relationships of the Liolaemus rothi complex and a new species of lizard from Auca Mahuida Volcano (Squamata: Liolaemini).

A new species of lizard of the genus Liolaemus from Neuquén Province, western Argentina, is described. The new species is a member of the Liolaemus rothi species complex, and mitochondrial and nuclear molecular data show it as sister taxon of the clade composed of (L. hermannunezi (L.
