Claparede 1868 (Polychaeta, Spionidae) is a mollusk shell-boring species which has been reported as a harmful species. In the present study, we sequenced and reported the mitochondrial genome (mitogenome) of from Korea. Its mitogenome was determined by long range PCR and primer walking. The mitogenome was found to be 17,707 bp in length and contained two ribosomal RNAs (rRNAs), 23 transfer RNAs (tRNAs), and 12 protein-coding genes which showed different gene arrangement with that in related mitogenomes of species of Sedentaria (Annelida). Interestingly, the 8 gene was not found in the mitogenome of , whereas it is present in the mitogenomes of related species and . Moreover, 2 (3' end) and 1 (5' end) genes overlapped in 23 bases. The mitogenome structure and gene contents of provide useful information on the evolution and phylogenetic relationship among polychaete species.
克拉帕雷德1868年（多毛纲，海稚虫科）是一种蛀食软体动物贝壳的物种，已被报道为有害物种。在本研究中，我们对来自韩国的[该物种名称未给出]进行了线粒体基因组（线粒体基因组）测序并进行了报道。其线粒体基因组通过长片段PCR和引物步移法确定。发现该线粒体基因组长度为17707 bp，包含两个核糖体RNA（rRNA）、23个转运RNA（tRNA）和12个蛋白质编码基因，其基因排列与定居亚纲（环节动物门）相关物种的线粒体基因组不同。有趣的是，在[该物种名称未给出]的线粒体基因组中未发现8基因，而在相关物种[物种名称未给出]和[物种名称未给出]的线粒体基因组中存在该基因。此外，2个基因（3'端）和1个基因（5'端）在23个碱基处重叠。[该物种名称未给出]的线粒体基因组结构和基因内容为多毛类物种的进化和系统发育关系提供了有用信息。
