The genus is one of the widespread freshwater bivalves. To date, its intra-generic phylogeny remains controversial and therefore the mitochondrial genome data is needed. Here, we report the complete mitogenome of MG that is distributed in the Chihe River, a branch of Huaihe River, East China. This mitochondrial genome is 15,764 base pair in total length. It consists of 37 genes: 13 protein-coding genes, 22 tRNA genes, and 2 rRNA genes (12S and 16S). The base composition was 38.38% for A, 26.48% for T, 23.17% for C, and 11.98% for G, showing an obvious bias of higher A + T content (64.86%) than the G + C content (35.14%). Phylogenetic analysis showed that MG is clustered with other and mollusks in the family Unionidae. These results showed that combine with morphological techniques, the mitogenome can provide useful information to further understanding of the genetics, systematics, and conservation of this endangered species.
该属是广泛分布的淡水双壳类动物之一。迄今为止，其属内系统发育仍存在争议，因此需要线粒体基因组数据。在此，我们报道了分布于中国东部淮河支流浉河的MG的完整线粒体基因组。这个线粒体基因组全长15764个碱基对。它由37个基因组成：13个蛋白质编码基因、22个tRNA基因和2个rRNA基因（12S和16S）。碱基组成为：A占38.38%，T占26.48%，C占23.17%，G占11.98%，显示出明显的A+T含量（64.86%）高于G+C含量（35.14%）的偏向性。系统发育分析表明，MG与蚌科的其他和软体动物聚集在一起。这些结果表明，结合形态学技术，线粒体基因组可以为进一步了解这种濒危物种的遗传学、系统学和保护提供有用信息。
