الوصف: The Pyrrhura lepida species complex currently consists of four taxa: P. l. lepida, P. l. coerulescens, P. l. anerythra, and P. perlata. It occurs south of the Amazon River, and is distinguished within the genus by a dark red upper tail and black under tail, as well as by having wider rectrices. The aim of this paper was to describe the morphological variation present in these taxa, and to revise their taxonomy and geographic distribution. Morphometric data revealed the absence of sexual dimorphism and did not allow the diagnosis of any taxon. Furthermore, morphological analysis, according to patterns of plumage of 174 specimens, resulted in the recognition of only three valid taxa that should be treated as full species: P. perlata, P. anerythra and P. coerulescens. A small hybrid zone between the latter two species was detected west of the mouth of the Tocantins River, and its establishment seems to be related to an already known geological shift in the course of the Tocantins River.
