In this study, we report the first complete mitochondrial genome of the tapeworm in the order Nippotaeniidea Yamaguti, 1939. This mitogenome, which is 14,307 base pairs (bp) long with an A + T content of 72.2%, consists of 12 protein-coding genes, 22 transfer RNA (tRNA) genes, two rRNA genes, and two non-coding regions. Most tRNAs have a conventional cloverleaf structure, but and lack dihydrouridine arms of tRNA. The two largest non-coding regions, NCR1 (220 bp) and NCR2 (817 bp), are located between and and between and , respectively. Phylogenetic analyses of mitogenomic data indicate that is closely related to tapeworms in the order Cyclophyllidea.
在这项研究中，我们报告了第一个完整的线粒体基因组属于 1939 年 Yamaguti 命名的膜壳绦虫目（Nippotaeniidea）。这个线粒体基因组全长 14307 个碱基对（bp），A+T 含量为 72.2%，由 12 个蛋白质编码基因、22 个转移 RNA（tRNA）基因、两个核糖体 RNA（rRNA）基因和两个非编码区组成。大多数 tRNA 具有典型的三叶草结构，但 和 缺乏 tRNA 的二氢尿嘧啶臂。两个最大的非编码区，NCR1（220bp）和 NCR2（817bp），分别位于 和 之间以及 和 之间。基于线粒体基因组数据的系统发育分析表明，膜壳绦虫与圆叶目（Cyclophyllidea）的绦虫关系密切。
