The missing leopard lizard: Liolaemus ubaghsi sp. nov., a new species of the leopardinus clade (Reptilia: Squamata: Liolaemidae) from the Andes of the O'Higgins Region in Chile.

Liolaemus is an extremely species rich genus of iguanid lizards from southern South America. Most of the diversity though is found in the Andes Cordillera, between Argentina and Chile View Article and Find Full Text PDF

Liolaemus carlosgarini and Liolaemus riodamas (Squamata: Liolaemidae), two new species of lizards lacking precloacal pores, from Andean areas of central Chile.

Most of the lizards of the Liolaemus genus present precloacal pores in males, with few exceptions in species of the lineomaculatus and neuquensis groups, and in the elongatus-kriegi complex. The elongatus-kriegi complex, belonging to the Liolaemus (sensu stricto) subgenus, is composed of medium sized, saxicolous, viviparous and insectivorous or omnivorous lizards, distributed between the Andean and Patagonian zones of Chile and Argentina. We reviewed the taxonomic history of this group, and we describe two new species, Liolaemus carlosgarini, found in the vicinity of the Maule Lagoon, in the Maule Region, Chile, and Liolaemus riodamas, described from the population that was originally designated as Liolaemus cf ceii, from Las Damas River, near the Termas del Flaco locality, in the Libertador Bernardo O'Higgins Region, thereby based on this research L.

Body proportions, microhabitat selection, and adaptive radiation of Liolaemus lizards in central Chile.

A biometric analysis of body proportions with presumably functional meaning for microhabitat selection was made on 12 species of Liolaemus lizards in central Chile. Characters studied were forelimb length, hindlimb length, tail length (all standardized by the corresponding snout-vent length), and the ratio forelimb/hindlimb length. It is shown that irrespective of terrestrial, saxicolous, or arboreal habits, Liolaemus species are remarkably similar in body proportions.

Escaping behavior and morphological correlates in two Liolaemus species of Central Chile (Lacertilia: Iguanidae).

Two central Chile lizards differ in their response to the approach of potential predators: Liolaemus lemniscatus escapes from rocky patches into grassy patches, and Liolaemus fuscus runs away from a rock onto another within the same rocky patch. These escaping responses are associated with concealing coloration and comparatively shorter legs in L. lemniscatus, as compared to L.
