The family Epialtidae is the most diversified family within superfamily Majoidea but there is no report for complete mitogenome of any species in this family. This study was performed to sequence a complete mitogenome of Stimpson, 1857, as the first mitochondrial genome report from the Epialtidae. The complete mitogenome sequence of was 16,415 bp and it consisted of 36 genes, including 13 protein-coding genes (PCGs), two rRNA genes, and 21 tRNA genes excluding tRNA-Leu (UAG). tRNA genes ranged from 63 bp to 72 bp in length. The base composition of a complete mitogenome of is 34.7% A, 15.3% C, 10.2% G, and 39.8% T. The phylogenetic position of in the superfamily Majoidea was examined based on 13 PCGs. The phylogenetic analysis showed that was most closely related to , a representative of the family Mithracidae.
扇蟹科是蜘蛛蟹总科中最多样化的科，但该科任何物种的完整线粒体基因组都没有相关报道。本研究对1857年的史氏扇蟹（学名：Epialtus stimpsoni）的完整线粒体基因组进行了测序，这是扇蟹科的首个线粒体基因组报告。史氏扇蟹的完整线粒体基因组序列为16,415 bp，由36个基因组成，包括13个蛋白质编码基因（PCGs）、两个rRNA基因和21个tRNA基因（不包括tRNA-Leu（UAG））。tRNA基因长度在63 bp至72 bp之间。史氏扇蟹完整线粒体基因组的碱基组成为：A占34.7%、C占15.3%、G占10.2%、T占39.8%。基于13个PCGs对史氏扇蟹在蜘蛛蟹总科中的系统发育位置进行了研究。系统发育分析表明，史氏扇蟹与蜘蛛蟹科的代表物种光辉圆扇蟹（学名：Cyclograpsus granulatus）关系最为密切。
