We first determined the complete mitochondrial genome of the White-spotted guitarfish (Rajiformes, Rhinobatidae). The complete mitogenome was 16,804 bp, with a base composition of 32.3% A, 27.5% T, 26.9% C and 13.3% G, containing 13 protein-coding genes, two rRNAs, 22 tRNAs and a control region (D-loop). It had 35 bp short intergenic spaces and 39 bp overlaps between genes. The gene order and composition of was similar to most other fishes. The codon usage followed the typical vertebrate mitochondrial pattern (ATG or GTG for start codon and TAA or T for stop codon). The phylogenetic result showed that was clustered with the Rhinobatos.
我们首先测定了白斑犁头鳐（鳐形目，犁头鳐科）的完整线粒体基因组。完整的线粒体基因组为16,804 bp，碱基组成为32.3%的A、27.5%的T、26.9%的C和13.3%的G，包含13个蛋白质编码基因、两个rRNA、22个tRNA和一个控制区（D环）。它有35 bp的短基因间隔和基因间39 bp的重叠。其基因顺序和组成与大多数其他鱼类相似。密码子使用遵循典型的脊椎动物线粒体模式（起始密码子为ATG或GTG，终止密码子为TAA或T）。系统发育结果表明，它与犁头鳐属聚在一起。
