Abstract
Introduction: The relationships within the Pyrrhura species complex are partly unresolved. In this study, a comprehensive phylogenetic analysis of the Pyrrhura picta-leucotis complex was carried out, covering all species except P. subandina. Material and Methods: We made a morphological analysis of 745 preserved specimens of all the taxa in different museums. Nucleotide sequences of the mitochondrial cytochrome gene were generated and used to reconstruct a molecular phylogeny of Pyrrhura. Results and Discussion: Our results show that the complex is divided into 6 main groups comprising 15 species. P. dilutissima, regarded up to now as a subspecies of P. peruviana, acquires species status and three new subspecies are described. We also provide evidence that P. roseifrons is a paraphyletic group, indicating the existence of probably 3 lineages of which 2 deserve species status.
Highlights
The relationships within the Pyrrhura species complex are partly unresolved
The most probable explanation for the picta-leucotis complex is that the splitting up of populations and taxa is very recent and reproductive isolation is still incomplete
The comparison shows that species status for griseipectus is justified
