The complete mitochondrial (mt) genome of (De Haan, 1841) is 16,131 bp in length, comprising 13 protein-coding genes (PCGs), 22 transfer RNA genes, and two ribosomal RNA genes. The nucleotide composition for is 34.3% of A, 36.6% of T, 10.9% of C, and 18.3% of G. All PCGs are initiated by ATN codons, except for the 1 gene, which was not determined. Nine PCGs use a common stop codon of TAA or TAG, the other four end with an incomplete stop codon (a single stop nucleotide T). Phylogenetic tree analysis showed that had a close relationship with the species from the family Thalassinidae. The study will provide an important theoretical basis for further analysis of mt genome evolution and the phylogenetic relationships of the order Decapoda.
（德哈恩，1841年）的完整线粒体（mt）基因组长度为16,131 bp，包括13个蛋白质编码基因（PCGs）、22个转运RNA基因和两个核糖体RNA基因。该物种的核苷酸组成为：A占34.3%，T占36.6%，C占10.9%，G占18.3%。除了未确定的1个基因外，所有PCGs均由ATN密码子起始。9个PCGs使用常见的终止密码子TAA或TAG，另外4个以不完全终止密码子（单个终止核苷酸T）结束。系统发育树分析表明，该物种与蝼蛄虾科的物种关系密切。该研究将为进一步分析mt基因组进化和十足目系统发育关系提供重要的理论依据。
