Currently are recognized 138 species in the genus Atractus, distributed from the eastern region of the Isthmus of Panama to northern Argentina. In recent years, many species have been described based on external morphological differences and hemipenis. Here we described the variation in meristic character in the newly described specie Atractus tartarus from the eastern Brazilian Amazon from the Xingu region. Additionally we present a preliminary hypothesis of relationship with your relatives, based on marker 16SmtDNA.
