Blue-throated Macaw (Ara glaucogularis) is Critically Endangered species of parrot endemic to small Bolivian area. In this study, full mitochondrial genome of considered species was sequenced. It is 16,983 bp long and contains 13 protein-coding genes, 2 rRNAs, 22 tRNAs and a control region. It`s comparison with published Ara macao mitogenome revealed their high degree of identity. On the other hand, analysis of both the genome compositions showed incompleteness of Ara macao CYTB gene. Hence, mitogenome of Ara macao species occurred only partial sequence. In consequence, Ara glaucogularis mitogenome is the first complete Macaw sequence, which will be indispensable to refine the phylogenetic relationships within the tribe Arini and will enrich the resource of markers for systematic, phylogenetic and population genetic studies.
蓝喉金刚鹦鹉（Ara glaucogularis）是一种极度濒危的鹦鹉物种，仅分布于玻利维亚的小片区域。在本研究中，对该物种的完整线粒体基因组进行了测序。其长度为16,983 bp，包含13个蛋白质编码基因、2个rRNA、22个tRNA和一个控制区。与已发表的绿翅金刚鹦鹉（Ara macao）线粒体基因组进行比较，发现它们具有高度的同一性。另一方面，对两者基因组组成的分析表明绿翅金刚鹦鹉CYTB基因不完整。因此，绿翅金刚鹦鹉物种的线粒体基因组仅出现了部分序列。结果，蓝喉金刚鹦鹉的线粒体基因组是首个完整的金刚鹦鹉序列，这对于完善阿苏儿族（Arini）内部的系统发育关系将不可或缺，并将丰富系统发育、系统学和群体遗传学研究的标记资源。
