RESUMO
The Military Macaw is one of the eight species of the genus Ara. The genus is one of six genera, which form morphologically diverse group termed as Macaws. Parrots of this group differ in body size on demand of the genus and species. Six of Ara species are classified as large Macaws. Based on morphological similarities and differences, these species can be segregated into three pairs according to their plumage coloration. Representative mitochondrial genomes were sequenced only for A. glaucogularis (blue and yellow coloration) and A. macao (predominantly red/scarlet). Ara militaris is one of two predominantly green species and full mitochondrial genome of considered species was sequenced in this study. It's comparison with A. glaucogularis and A. macao mitogenomes revealed higher degree of identity between militaris and macao sequences than between militaris and glaucogularis mtDNAs. Ara militaris mitogenome will be indispensable to refine the phylogenetic relationships within Macaw group.
