The aim of this study was to determine the patterns of morphological variation in color and design, verify that these patterns are related to the presence of Amazonian rivers, verify the degree of genetic structure among populations of C. hortulanus throughout its distribution and verify that the major south interfluves of the Amazon basin represent genetically structured populations. For morphologic data were analyzed the color pattern of 125 specimens and for molecular data were generated 103 sequences of COI and 38 of CITB. Six morphotypes were described for populations from south of the Amazon River. It was observed that the rivers of south of the Amazon River showed a mixed pattern, which Tocantins, Xingu and Madeira rivers did not influence the genetic structure, while Purus and Tapajós rivers acted as a geographical barrier for populations of C. hortulanus, and only in one case the genetic structure was found in all analyzes (Purus).porAcesso AbertoAnfíbioSerpentesCorallus hortulanusVariação morfológicaRio AmazonasAmazônia brasileiraDissertaçãoCNPQ::CIENCIAS BIOLOGICAS::ZOOLOGIA::MORFOLOGIA DOS GRUPOS RECENTES
