Abstract
Arini with 19 genera is the most diversified tribe of the neotropical parrots from Arinae subfamily. So far, among this tribe, the genus Aratinga appeared to be the most problematic for the taxonomists. The typical representative of this genus is Aratinga solstitialis, whose complete mitochondrial genome were sequenced and compared with five other representatives of Arini mitogenomes. Despite the conservatism in their general organization, some changes in A + T% composition of individual genes, start/stop codon usage and intergenic regions accumulated during evolution.
