The dragonfly Okumura, 1949 (Odonata: Macromiidae) has been listed as an Endangered insect in South Korea. We sequenced the complete 15,198 bp mitochondrial genome (mitogenome) of this organism, which is the first mitogenome sequence reported from the family Macromiidae. The genome includes a typical set of genes [13 protein-coding genes (PCGs), 2 rRNA genes, and 22 tRNA genes) and one non-coding region with an arrangement identical to that observed in most insect genomes. Phylogenetic analyses using concatenated sequences of the 13 PCGs and 2 rRNA genes using the Bayesian inference (BI) method placed Macromiidae, represented by , as a sister group to Libellulidae with the highest nodal support [Bayesian posterior probabilities (BPP) = 1]. Unlike conventional phylogenetic analysis, the suborders Anisozygoptera and Zygoptera formed a strong sister group (BPP =1), justifying the use of different molecular markers for phylogenetic analysis.
冈村大蜓（1949年命名，蜻蜓目：大蜓科）在韩国已被列为濒危昆虫。我们对该物种完整的15,198碱基对线粒体基因组（线粒体基因组）进行了测序，这是大蜓科首次报道的线粒体基因组序列。该基因组包含一组典型的基因[13个蛋白质编码基因（PCG）、2个rRNA基因和22个tRNA基因]以及一个非编码区，其排列与大多数昆虫基因组中观察到的相同。使用贝叶斯推断（BI）方法对13个PCG和2个rRNA基因的串联序列进行系统发育分析，以冈村大蜓为代表的大蜓科作为蜻科的姐妹群，具有最高的节点支持率[贝叶斯后验概率（BPP）=1]。与传统的系统发育分析不同，差翅亚目和均翅亚目形成了一个强有力的姐妹群（BPP =1），这证明了在系统发育分析中使用不同分子标记的合理性。
