Many studies have reported the complete mitochondrial genome sequences of Chinese Megascolecidae earthworms, however, there have been no reports on sequences originating from Japanese Megascolecidae earthworms. In this study, we determined complete mitochondrial genome sequences of two Japanese earthworms belonging to the complex within the Megascolecidae family. is one of the most common earthworms in Japan and was found to be morphologically similar to . The complete mitochondrial genomes of (15,186 bp; LC573968) and (15,109 bp; LC573969) contained typical 13 protein coding genes, 22 tRNA genes, and 2 rRNA genes. The phylogenetic analysis revealed that these two species were sister species. Therefore, our findings will further contribute to phylogenetic and genetic diversity analyses of Megascolecidae earthworms.
许多研究报告了中国巨蚓科蚯蚓的完整线粒体基因组序列，然而，尚无源自日本巨蚓科蚯蚓序列的相关报道。在本研究中，我们测定了巨蚓科家族内两个属于该复合体的日本蚯蚓的完整线粒体基因组序列。 是日本最常见的蚯蚓之一，并且发现其在形态上与 相似。 （15,186 bp；LC573968）和 （15,109 bp；LC573969）的完整线粒体基因组包含典型的13个蛋白质编码基因、22个tRNA基因和2个rRNA基因。系统发育分析表明这两个物种是姐妹物种。因此，我们的研究结果将进一步有助于巨蚓科蚯蚓的系统发育和遗传多样性分析。
