Studying the geographic distribution patterns of organisms and the processes that generate such patterns is fundamental to Biogeography. It is believed that the diagonal development of South American open vegetation, which includes Cerrado, Caatinga, Chaco and Pampas, corresponded to a vicarious process for several groups of forest animals and plants. We suggest to test this hypothesis using a clade of forest jararacas composed of 17 species of the genus Bothrops (Serpentes, Viperidae). The species occupy mainly forest regions of South America, with the exception of B. moojeni, that is distributed in open areas of the Cerrado and Caatinga. From the reconstruction of the geographic distribution areas of the hypothetical ancestors of the group, it will be possible to infer the importance of the processes that generated the patterns of current geographical distribution. The project may contribute to the recurrent discussion about the validation or not of the open diagonal as a vicarious process in the Neotropical region, which has the most diverse biota on the planet.
