    Animal coloration is an important biological attribute with different functions related to the strategies adopted by individuals in the environment, such as thermoregulation, defense and inter and intraspecific communication. The mimicry is perhaps one of the most important biological communication mechanisms, often involving similarity of color with a defensive connotation. Systems mimetics reflect a complex evolution process that accentuates similarities morphological or behavioral between two or more species guaranteeing adaptive advantages at least one. Though common between invertebrates, mimicry also observed in vertebrate groups as lizards and serpents eg. For examples common mimicry snakes are described relations between corals true and false. The false coral, Atractus latifrons (Günther, 1868) is endemic in the Amazon and occurs in the Brazil, Colombia, French Guiana, Peru, Suriname and Venezuela. Due to the similarity of their different color patterns, this species was related to some species of the genus Micrurus coral snakes that also have Amazon distribution. Although the chromatic variation of this species has been reported by some authors, some questions about the intraspecific polymorphism and its relation to geographic distribution, as well as the mimetic relationship with the coral snakes Micrurus not yet been studied. With the purpose of contribute to the elucidation of these issues, this study was organized into two chapters: In first entitled "Variation Morphological and Taxonomy Atractus latifrons (Günther, 1868) (Serpentes: Dipsadidae)" were presented morphological variations species including descriptions their standards chromatic and variations morphological intraspecific A. latifrons and analysis sexual dimorphism group; in second chapter entitled "Relations mimicry between Atractus latifrons and corals true Amazon" were identified for possible models mimetics A. latifrons, inferring their mimetic relationships through the analysis of co-occurrence and distribution maps showing patterns among mimetic species involved.
