abtract The presence of bare facial area distinguishes Macaws from other members of the Arini tribe. Genera and species of the Macaw group differ in pattern of this bare skin as well as in body size. Individuals of the genera: Diopsittaca, Orthopsittaca, and Primolius are significantly smaller than the members of the genera: Anodorhynchus, Cyanopsitta, and the most species of the genus Ara. The genus Primolius contains three species: P. auricollis, P. couloni, and P. maracana, which are classified as medium-sized Macaws. So far, mitochondrial genome representative for the genus was sequenced only for Primolius couloni species. Primolius maracana mitogenome, which was sequenced in this study, will be indispensable to refine the phylogenetic relationships between Primolius species, as results of molecular researches seems to be inconsistent with Primolius species morphology.
Keywords: Arini; Primolius maracana; Psittaciformes; blue-winged Macaw; mitogenome.
