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

Abstract

Two new species of the Liolaemus donosobarrosi clade are described. Liolaemus tirantii sp. nov. and Liolaemus calliston sp. nov. differ from other members of their clade by a combination of coloration characters, morphometric and molecular traits. Liolaemus tirantii sp. nov. is known from three localities separated only a few kilometers from each other and Liolaemus calliston sp. nov. is known only from the type locality. Both species inhabit a region strongly impacted by oil and gas extraction but their conservation status is unknown.
