--- A revision of the species of the genus Atractus that inhabit Peru was made using external morphological characters (morphometry and meristics), in a total of 14 species. Diagnosis and a key to the species of the genus for Peru are presented and the taxonomic value of their characters is evaluated through a principal component and a discriminant analysis: establishing the length of rostral and loreal scales as crucial characters to the creation of species groups; two species groups are formed: badius and elaps. Cluster analysis were also made in order to support the creation of these species groups. The status of four species is discussed and a possible new species is identified. A distribution map of the Atractus species found in Peru is also shown and the biogeographic hypotheses among these groups are discussed. Apparently, the origin of this genus is the Amazon, and it migrated to the west, only in the species of the badius group.
