A revision of the Aratinga mitrata complex, with the description of one new species, two new subspecies and species-level status of Aratinga alticola

摘要

Prompted by field observations in 2001 in the Utcubamba Valley, Peru, a study was undertaken of 130 specimens in the Aratinga mitrata complex. As a result, the traditional arrangement of Aratinga mitrata (A. m. mitrata Tschudi 1844 and A. m. alticola Chapman 1921) as one species, is replaced with a new classification where Aratinga mitrata is divided into five taxa, A. m. mitrata Tschudi 1844, Aratinga mitrata chlorogenys ssp. nov and Aratinga mitrata tucumana ssp. nov, Aratinga hockingi sp. nov, and A. alticola Chapman 1921.
