In this study, we first present the complete mitochondrial genome of , the only member of genus in family Hemigaleidae. It is 16,691 bp in length with the typical gene order invertebrates. Its overall base composition is 31.7% A, 24.1% C, 12.9% G and 31.3% T. Two start codons (ATG and GTG) and three stop codons (TAG, AGA and TAA/T) are found in the protein-coding genes. The 22 tRNA genes ranged from 67 bp (tRNA-, tRNA-2) to 75 bp (tRNA-1). The phylogenetic result showed that was clustered to and formed Hemigaleidae.
在本研究中，我们首次展示了半锯鲨科中 属唯一成员的完整线粒体基因组。它长度为16,691 bp，具有无脊椎动物典型的基因排列顺序。其总体碱基组成为31.7%的A、24.1%的C、12.9%的G和31.3%的T。在蛋白质编码基因中发现了两个起始密码子（ATG和GTG）和三个终止密码子（TAG、AGA和TAA/T）。22个tRNA基因长度从67 bp（tRNA- 、tRNA-2）到75 bp（tRNA-1）不等。系统发育结果表明， 聚类到 并形成半锯鲨科。
