          Abstract

          Abstract The region of Volta Grande do Xingu River, in the state of Pará, presents several kinds of land use ranging from extensive cattle farming to agroforestry, and deforestation. Currently, the Belo Monte Hydroelectric Power Plant affects the region. We present a checklist of amphibians and reptiles of the region and discuss information regarding the spatial distribution of the assemblies based on results of Environmental Programmes conducted in the area. We listed 109 amphibian (Anura, Caudata, and Gymnophiona) and 150 reptile (Squamata, Testudines, and Crocodylia) species. The regional species richness is still considered underestimated, considering the taxonomic uncertainty, complexity and cryptic diversity of various species, as observed in other regions of the Amazon biome. Efforts for scientific collection and studies related to integrative taxonomy are needed to elucidate uncertainties and increase levels of knowledge of the local diversity.

          Resumo A região da Volta Grande no Rio Xingu, localizada no estado do Pará, apresenta várias frentes de exploração que vão desde a criação animal até área de cultivo, resultando no desmatamento de fragmentos florestais. Atualmente a região está sendo impactada pela implantação da Usina Hidrelétrica de Belo Monte. A partir de dados obtidos através dos Programas de Monitoramento Ambiental realizados na área de influência da UHE Belo Monte, apresentamos uma listagem das espécies de anfíbios e répteis, com comentários sobre a distribuição espacial das assembleias. Foram catalogados 109 espécies de anfíbios (Anura, Caudata e Gymnophiona) e 150 de répteis (Squamata, Testudines e Crocodylia). Considerando as incertezas taxonômicas, a complexidade e a diversidade críptica de várias espécies, a riqueza regional ainda continua subestimada, assim como observado em outras regiões da Amazônia. Esforços direcionados ao aproveitamento científico e estudos que contemplem a taxonomia integrativa são necessários para elucidar as incertezas e aumentar o nível de conhecimento sobre a diversidade da região.
