The complete mitochondrial genome of convex reef crab was determined and characterized for the first time from the South China Sea. The whole mitogenome is 15,766 bp long and consists of 22 tRNA genes, 2 rRNA genes, 13 protein-coding genes (PCGs), and 1 control region. The nucleotide composition of the mitogenome is significantly biased (A, G, T, and C is 36.91%, 17.94%, 34.95%, and 10.19%, respectively) with A + T contents of 71.86%. All PCGs start with a normal initiation codon ATN and terminate with a standard stop codon except ND1 gene end with TTG. Five microsatellites are identified in mitogenome sequences. The phylogenetic tree showed that was first clustered with , and strongly supports that the recognition of the Carpiliidae as a monophyletic family.
首次测定并表征了来自中国南海的凸礁蟹的完整线粒体基因组。整个线粒体基因组长度为15766 bp，由22个tRNA基因、2个rRNA基因、13个蛋白质编码基因（PCGs）和1个控制区组成。线粒体基因组的核苷酸组成存在显著偏差（A、G、T和C分别为36.91%、17.94%、34.95%和10.19%），A+T含量为71.86%。所有PCGs均以正常起始密码子ATN开始，除ND1基因以TTG结尾外，均以标准终止密码子结束。在mitogenome序列中鉴定出五个微卫星。系统发育树显示，首先与聚类，强烈支持将梭子蟹科认定为单系科。
