The identification of natural biogeographical regions is fundamental for comparisons in broad-scale ecological and evolutionary studies, and constitutes an essential tool for conservation planning. Several recent ecological and biogeographical studies have attempted to delimit bioregions at both global and local scales, and there is a long history of regionalization schemes proposed for the Neotropical region throughout the last 150 years. However, despite recent advances and proposals, there is no consensus on what kind of data are most adequate, what are the best methods for delimitating and mapping bioregions cartographically, nor which terminological system should be used for referring to the areas identified. This lack of consensus, as well as its insufficient analytical development, is surprising given that these natural units form the basis for the study of evolutionary, ecological, and geological process that spatially structure biotas. Thus, the aim of this study is to test methods and proposals of regionalization in Neotropics using real and reliable data (ca. 100,000 distributional records of 469 species) on the geographical distribution of snakes as a model, and to compare the results with previously published proposals for other animals, plants, and abiotic features. We aim to answer the following questions: i) How do different bioregionalisation methods perform on the distributional data of Neotropical snakes? ii) How congruent are commonly recognized "Brazilian biomes" with bioregions delimited by distributional data of snakes? iii) What are the main limitations of currently available methods used in regionalization analyses for biogeography?
