At present, only several species of genus were described and information of mitochondrial DNA were also just focused on two species. Here, the complete mitochondrial genome of was completely sequenced by high throughput sequencing method. The complete mitochondrial genome was 16,614 bp in length, consisted of 13 protein-coding genes, 22 tRNA genes, 2 rRNA genes, 1 large non-coding control region, and 1 light-strand replication origin. Overall base composition values for the mitochondrial genome were 28.24, 29.20, 16.77, and 25.79% for A, C, G, and T, respectively. The gene arrangement is identical to those in typical fishes. Phylogenetic tree based on 13 protein-coding genes shows that three species of genus did not cluster into one clade.
目前，仅描述了该属的几个物种，线粒体DNA信息也仅集中在两个物种上。在此，通过高通量测序方法对该属的完整线粒体基因组进行了全序列测定。完整的线粒体基因组长度为16,614 bp，由13个蛋白质编码基因、22个tRNA基因、2个rRNA基因、1个大的非编码控制区和1个轻链复制起点组成。线粒体基因组的总体碱基组成值中，A、C、G和T分别为28.24%、29.20%、16.77%和25.79%。基因排列与典型鱼类中的相同。基于13个蛋白质编码基因构建的系统发育树表明，该属的三个物种没有聚为一个分支。
