We assembled the complete mitochondrial genome (mitogenome) of (Scyphozoa: Rhizostomeae: Mastigiidae) by the data generated from the next-generation sequencing platform. The complete mitogenome of was 16,560 bp in length, containing 14 protein-coding genes, two transfer RNA genes, and two ribosomal RNA genes. The base compositions were A 30.65%, C 15.16%, G 16.34%, and T 37.86%, with a gene arrangement similar to the mitogenomes derived from other representatives of Scyphozoa. Based on the 13 common protein-coding genes of 16 species within Scyphozoa, we constructed the phylogenetic tree and found that has a close relationship with and . All these species belong to an order of jellyfish Rhizostomeae, which have similar morphological characteristics. This is agreement with the conclusion we got by the phylogenetic relationship analysis using molecular data. This research has practical implications for advancing understanding of the phylogenetic relationships, taxonomic classifications, and phylogeography within Scyphozoa.
我们利用下一代测序平台生成的数据，组装了（钵水母纲：根口水母目：鞭腕水母科）的完整线粒体基因组（线粒体基因组）。的完整线粒体基因组长度为16,560 bp，包含14个蛋白质编码基因、两个转运RNA基因和两个核糖体RNA基因。碱基组成为A 30.65%、C 15.16%、G 16.34%和T 37.86%，其基因排列与钵水母纲其他代表物种的线粒体基因组相似。基于钵水母纲16个物种的13个常见蛋白质编码基因，我们构建了系统发育树，发现与和关系密切。所有这些物种都属于根口水母目的一种水母，它们具有相似的形态特征。这与我们通过分子数据进行系统发育关系分析得出的结论一致。这项研究对于推进对钵水母纲内系统发育关系、分类学分类和系统地理学的理解具有实际意义。
