Two New Species of Liolaemus (Iguania: Liolaemidae) from the Puna of Northwestern Argentina

Abstract We describe two new species of Liolaemus belonging to the montanus series. The new species are closely related to L. dorbignyi, but are disjunctly distributed with respect to this taxon. Both new species exhibit unique color patterns, which, along with differences in squamation, differentiate the two new taxa from the other species in the series. Both new species are saxicolous and inhabit rocky hills in the Puna regions of northwestern Argentina. One occurs in the Cerro de la Virgen, Nevados de Cachi and Nevados de Palermo of Salta Province. The other is known only from its type locality in the Cerro El Pichao of Tucumán Province.

Two New Species of Liolaemus (Iguania: Liolaemidae) of Central West Argentina

Abstract We describe two new species of lizards of the genus Liolaemus belonging to the chiliensis group, one found in southwestern Catamarca, and the other in central western Argentina, in Mendoza, San Juan and Catamarca provinces. The species from southwestern Catamarca has morphological characteristics that may relate it to the species of the capillitas group, a northern clade of the elongatus group, whereas the other species has characters that relate it to the southern clade of the elongatus group. Both species exhibit diagnoistic character states in their maximum snout-vent length, squamation, and dorsal and ventral colors, which differentiate them from the other species of the chiliensis group.

Taxonomy of the Liolaemus alticolor–bibronii Group (Iguania: Liolaemidae), with Descriptions of Two New Species

Abstract Liolaemus alticolor is redescribed herein, providing new character states that distinguish this taxon from all other members of the alticolor–bibronii group. Two new species of the alticolor–bibronii group are also described. One of the new species occurs in northern Argentina, in the Jujuy Province, whereas the other occurs in southern Argentina, in the Neuquén Province (northern Patagonia). Both of them exhibit characters that distinguish them from each other and from all other members of the alticolor–bibronii group. A key to the species of this group is provided.

The Iguanian Lizard Liolaemus barbarae Pincheira-Donoso and Núñez Is a Junior Synonym of Liolaemus puna Lobo and Espinoza

Abstract Liolaemus barbarae was recently described from northern Chile. However, the character states used to distinguish this species from Liolaemus puna are not exclusive. We reassessed the character states used for the diagnosis of L. barbarae and compared these with data from the type series and additional specimens of L. puna. We found identical ranges or broad overlap in character states between the two species. We conclude that L. barbarae is a junior synonym of L. puna.

A New Species of Liolaemus (Iguania: Liolaemidae) of the alticolor-bibronii Group from Northern Chile

Abstract We describe a new slender species of Liolaemus of the L. alticolor-bibronii group of the subgenus Liolaemus. The new species is phenetically and biogeographically close to L. alticolor, L. paulinae, and L. puna but presents a combination of character states that differentiates it from all other species of Liolaemus. The new taxon is the first species of subgenus Liolaemus sensu stricto recorded as having supernumerary pores. The new species inhabits places where Parastrephia lucida is the predominant flora and is distributed in areas close to Putre, in the Arica y Parinacota region, northern Chile. Data on its biology, complete distribution, and conservation status are lacking.

A New Species of Liolaemus of the Liolaemus alticolor-bibronii Group (Iguania: Liolaemidae) from Mendoza, Argentina

Abstract. We describe a new species of Liolaemus of the L. alticolor-bibronii group of the subgenus Liolaemus sensu stricto. Liolaemus bibronii has a large geographic distribution; however, preliminary studies suggest that it comprises a species complex. The new species is phenetically similar to L. bibronii and was confused with this taxon for many years. Nevertheless, the new species presents a combination of character states that clearly differentiate it. Also, the new taxon is distributed far from L. bibronii type locality (ca. 1,600 km). It differs from other species of Liolaemus in presenting a unique color pattern and a combination of morphological character states from lepidosis and morphometry. The new species inhabits pre-Andean localities in Uspallata, Las Heras department, northwest Mendoza Province, and is an insectivorous and oviparous species. With the description of this new taxon, the number of species of the L. alticolor-bibronii group rises to 30, but many populations still remain undescribed.
