dc.descriptionThe genus Atractus is the most diverse into the snakes. Its distribution ranges from Panama to Argentina and there are several species occurring in Brazil. One of these is Atractus collaris. This species is described from Ecuador, but also occurs in Colombia, Peru and Brazil. Despite the wide distribution of this species, in Brazil there are only two previous records in literature. This may be related mainly to the Cryptozoic habit and insufficient samplings. However, we present a new record of Atractus collaris in Central Amazonia. This is the third record for Brazil and the easternmost record for this species.en-US
