A new species of Liolaemus (Iguania: Liolaemidae) from the hot deserts of northern Patagonia, Argentina

A new species of Liolaemus is described from southwest the town Añelo, Neuquén Province, Argentina. Integrative evidence methodology external morphological characters and molecular phylogenetic analyses mitochondrial DNA (cyt-b) used to place group boulengeri. The phenotypically close L. mapuche. medium large in size (males 77.64–83.98 mm, females 72.88–78.58 mm), with evident sexual dichromatism. Genetic distances mtDNA between its closest relative are greater than 3% (L. cuyanus 7.48–12.02%; josei 7.56–9.60%; puelche 8.23–9.93%; mapuche 8.51–9.79%). Molecular results show as sister one. larger Dorsal ventral scales more numerous mapuche, precloacal pores present absent species. It has strict psammophilic habits, using sand mounds sheltering, under Alpataco (Neltuma alpataco) bushes. boulengeri now contains 75 distributed Argentina, Bolivia, Brazil, Chile, Paraguay, Peru Uruguay.
