Resumen
El Parque Nacional Traslasierra (PNT) se ubica al oeste de la provincia de Córdoba y abarca una superficie de 44 019 ha. Se extiende desde la cuenca hidrográfica de las Sierras de Pocho, al este, hasta el límite interprovincial con La Rioja, al oeste. Abarca bosques y matorrales del Chaco Serrano, extensos bosques xerófilos de llanura, y tierras bajas saladas y arbustos halófitos del extremo sur de las Grandes Salinas Centrales. Los vertebrados que habitan el Parque son típicos del Chaco árido, incluyendo poblaciones de especies en peligro de extinción. A pesar de ello, hasta la fecha no existe un estudio formal y completo de la herpetofauna del Parque. El objetivo de este trabajo es presentar una lista comentada de todos los reptiles confirmados en esta área protegida, así como una segunda lista de especies que probablemente formen parte del catálogo y que aún no se encuentran en el Parque, pero que cuentan con registros en sectores vecinos de fisonomía similar. Los registros de las especies provienen de observaciones realizadas por el primer autor y personal del PNT que realiza tareas diarias de vigilancia en el Parque, así como de nuestro trabajo de campo previo en la zona. Nuestros resultados confirman la presencia de 26 especies y subespecies, que corresponden al 35.6 % de los 73 reptiles nativos de la provincia de Córdoba. Cinco de ellas se encuentran amenazadas o vulnerables: Chelonoidis chilensis, Stenocercus doellojuradoi, Tropidurus spinulosus, Boa constrictor occidentalis y Epicrates alvarezi, y están protegidas por el PNT. La serpiente Rena unguirostris (Leptotyphlopidae), si bien presente en 12 provincias, estaría protegida solo en esta unidad del Sistema de Parques Nacionales de Argentina. De las 18 especies a confirmar en el Parque, siete son altamente probables debido a su presencia en el Parque Provincial y Reserva Forestal Natural Chancaní, distante 10 km al sur del Parque.
The Traslasierra National Park (TNP) is located in the west of the province of Córdoba, comprising an area of 44 019 ha. It extends from the watershed of the Sierras de Pocho, to the east, and to the interprovincial limit with La Rioja to the west. It includes forests and scrublands of the Chaco Serrano, extensive xeric plain forests, and salty lowlands and halophytic shrubs from the southern end of the Great Central Salinas. The vertebrates that inhabit the Park are typical of the arid Chaco, including populations of endangered species. Notwithstanding this fact, to date there is no formal and complete survey of the Park's herpetofauna. The objective of this work is to present an annotated list of all the reptiles confirmed in this protected area, and a second list of species likely to be part of the catalogue, still not found in the Park but with records in neighboring sectors with similar physiognomy to it. The species´ records come from observations by the first author and personnel of the TNP performing daily surveillance tasks in the Park, as well as the authors' previous field work in the area by ourselves. Our results confirm the presence of 26 species and subspecies, corresponding to 35.6 % of the 73 native reptiles of the province of Córdoba. Five of them are Threatened or Vulnerable: Chelonoidis chilensis, Stenocercus doellojuradoi, Tropidurus spinulosus, Boa constrictor occidentalis and Epicrates alvarezi, and are protected by the TNP. The leptotyphlopid snake Rena unguirostris, although present in 12 provinces, would be protected only in this unit of the National Park System of Argentina. Of the 18 species to be confirmed in the Park, seven of them are highly probable because they are present in the Chancaní Provincial Park and Natural Forest Reserve, 10 km south of the Park.
