The metaphases were obtained using a short term culture of leather pulp. Eleven of the twelve analyzed species were karyotypically homogeneous, with only a few divergences in chromosomes 2 and 3. The species A. xanthops showed large karyotypic differences compared to the genus Amazona. Consequently, the genus Salvatoria (Ribeiro, Rev. Mus. Paul. 12: 1-82, 1920) was confirmed, and A. xanthops renamed Salvatoria xanthops. The study showed the chromosomic conservation of the genus Amazona and the need for further taxonomic studies of the karyotype of the Psittacidae.
