We characterised, for the first time, the whole mitogenome of a unique tapeworm, Moniezia sichuanensis (Cyclophyllidea, Anoplocephalidae) of forest musk deer (Moschus berezovskii). The total length of the circular mitogenome was 13,652 bp. It consisted of 12 protein-coding genes (PCGs), 22 transfer RNA genes, and two ribosomal RNA genes, which are typical of the mitogenomes of Moniezia. By comparing the available mitogenomes of PCGs for Cyclophyllidea in GenBank, nad6 and cox1 showed the highest and lowest evolutionary rates, respectively, and cox2 could be used as a potential DNA barcoding marker. The phylogenetic analyses of Cyclophyllidea confirmed the monophyly of the genus Moniezia and the family Anoplocephalidae; they then formed a clade with species of Hymenolepididae. Moreover, two novel gene arrangements of Cyclophyllidea were observed.
我们首次对来自林麝（Moschus berezovskii）的一种独特的带绦虫，四川孟氏迭宫绦虫（Cyclophyllidea，膜壳科）的整个线粒体基因组进行了特征描述。该圆形线粒体基因组全长 13652bp，由 12 个蛋白编码基因（PCGs）、22 个转移 RNA 基因和两个核糖体 RNA 基因组成，这是孟氏迭宫绦虫线粒体基因组的典型特征。通过比较 GenBank 中已有的膜壳科 PCGs 的线粒体基因组，nad6 和 cox1 的进化速度分别最高和最低，cox2 可用作潜在的 DNA 条形码标记。膜壳科的系统发育分析证实了孟氏迭宫绦虫属和膜壳科的单系性，它们随后与膜头科的物种形成一个分支。此外，还观察到了两种新的膜壳科基因排列。
