Liolaemus tirantii 
Avila, Perez, Minoli, Medina, Sites & Morando, 2017


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.

Liolaemus tirantii sp. nov.

Etymology. To honor Sergio Igor Tiranti, an enthusiastic biologist, colleague and friend, who first discovered and collected the species in early 1990 at the type locality, and to his father Ivan Nicolas Tiranti, professor of genetics at the National University of Río Cuarto, Argentina, who helped the first author on its doctoral studies and shared its experiences and friendship in the academic world.

Liolaemus calliston sp. nov.

Etymology. The specific epithet is an adjective of Greek origin (calliston = very beautiful), in reference to the distinct and brightly colorful pattern of dorsal and lateral body of this new species.
