| Los sedimentos del Mioceno Temprano de la Formación Sarmiento en Gaiman, provincia del Chubut (Argentina) han provisto una de las más importantes colecciones de escamosos del Mioceno, incluyendo iguanios, teidos, boideos y colúbridos. En este trabajo se describen restos fragmentarios de iguanios asignados a los actuales Pristidactylus y Liolaemus, constituyendo los registros más antiguos para estos géneros. Los cambios climáticos y ambientales ocurridos durante el Neógeno en las áreas patagónicas habrían impactado diferencialmente sobre la fauna de escamosos, produciendo la retracción en la distribución de los teidos tupinambinos y las serpientes boideas y, contrariamente, la diversificación de los iguanios a ambos lados de los Andes. |

| The record of non-mosasaur squamates (Reptilia, Squamata) is sparse in the Cretaceus fossil record of Brazil and include six putative reports, three from the Aptian-Albian of the Araripe Basin (Tijubina pontei Bonfim-Júnior and Marques, Olindalacerta brasiliensis Evans and Yabumoto, and a lizard indet.) and three from the Upper Cretaceous of the Bauru Group (Pristiguana brasiliensis Estes and Price, Anilioidae gen. et sp. indet., and Squamata gen. et sp. indet.). In this contribution, a new genus and species of lizard, Brasiliguana prudentis gen. et sp. nov., is described based on an isolated left maxilla with teeth. The material was discovered in an outcrop of the Upper Cretaceous Adamantina Formation (Bauru Group) located in the proximity of Presidente... |

| We describe a new species of Enyalioides from lowland cloud forests in southwestern Ecuador. This represents the third species in the genus known to occur west of the Andes in South America; the other two species are E. heterolepis and E. oshaughnessyi. Among other characters, the new species can be distinguished from other members in the genus by having small, keeled, paravertebrals; a series of skin folds on the lateral aspects of body and neck; size-homogeneous scales on body and limbs; distinct caudal segments; and an extensive dark patch on the gular region of adult males. Morphological similarity suggests that the new species, which we call E. touzeti, is closely related to E. oshaughnessyi. |
