A new species of the Liolaemus elongatus clade (Reptilia: Iguania: Liolaemini) from Cordillera del Viento, northwestern Patagonia, Neuquén, Argentina

Abstract

A new species of lizard of the genus Liolaemus from Cordillera del Viento, northwestern Neuquén Province, Argentina is described. The new species is a member of the Andean-Patagonian Liolaemus elongatus clade and is known only from a single locality above 3000 m in the eastern slopes of Domuyo Volcano. Liolaemus antumalguen sp. nov. is a stout species, saxicolous, probably viviparous and omnivorous, and seems to have low population density. It is easily differentiated from all other species of the elongatus complex for a highly variable but characteristic dorsal pattern and a completely black ventral coloration.
