We update the list of lizards of Argentina, reporting a total of 261 species from the country, arranged in 27 genera and 10 families. Introduced species and dubious or erroneous records are discussed. Taxonomic, nomenclatural and distributional comments are provided when required. Considering species of probable occurrence in the country (known to occur in Bolivia, Brazil, Chile and Paraguay at localities very close to the Argentinean border) and still undescribed taxa, we estimate that the total number of species in Argentina could exceed 300 in the next few years.Key words: Reptiles, Liolaemus, Phymaturus, South America, list ResumenActualizamos la lista de lagartijas de la Argentina, presentamos un total de 261 especies para el país, organizados en 27 géneros y 10 familias.

Considerando especies de probable existencia en nuestro país (que se encuentran en Bolivia, Brasil, Chile y Paraguay en localidades muy cercanas al límite con Argentina) y taxas aún no descriptos, estimamos que el número total de especies en Argentina puede exceder las 300 en los próximos años.

It has long been considered sufficient a single method or only a descriptive diagnosis to propose a new species. Recently, many works have proposed new theoretical paradigms to consider multiple sources of evidence to support the hypothesis of new taxa within an integrative approach. Despite this, many new described species continue to be merely descriptive and without any reproducible statistical analysis to support these descriptions. We tested whether five species described as members of a species complex of the lizard genus Liolaemus from Patagonia, can be differentiated based on classical morphometric analyses and ecological niche modeling. Individuals were sampled from their type localities. Our results showed that the univariate tests and Principal Component Analyses (PCA) were more accurate to differentiate species compared to the Linear Discriminant Analyses (LDA). However, there were almost no morphometric differences between two of the analyzed species. Major differences were found in bioclimatic variables of four of the species through Maxent ENMs and PCA using the original worldclim variables. Our results partially support the hypothesis that species can be differentiated by classical morphometric analyses, and found a strong support for the hypothesis that these taxa can be differentiated through their bioclimatic niches. These two approaches based on repeatable statistical basis, can supplement qualitative descriptive diagnoses of new species of the genus Liolaemus.
