In this study, we first determined and characterized the complete mitochondrial genome of longlegged spiny lobster from South China Sea. The mitogenome is 15,739 bp long, and consists of 22 tRNA genes, two rRNA genes, 13 protein-coding genes (PCGs), and one control region. The nucleotide composition of mitogenome is significantly biased (A, G, T, and C was 32.06%, 14.36%, 32.42%, and 21.16%, respectively) with A + T contents of 64.48%. Among 13 PCGs, COX1 gene used an unusual initiation codon CAA, COX1, COX2, ND4 and CYTB genes were ended with an incomplete stop codon T, and ND5 gene with an abnormal stop codon ATT. One microsatellite (C) was identified in mitogenome located in the control region. Phylogenetic tree showed that was first clustered with , then together with and .
在本研究中，我们首先测定并表征了来自中国南海的长足刺龙虾的完整线粒体基因组。该线粒体基因组长度为15,739 bp，由22个tRNA基因、两个rRNA基因、13个蛋白质编码基因（PCGs）和一个控制区组成。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32.06%、14.36%、32.42%和21.16%），A+T含量为64.48%。在13个PCGs中，COX1基因使用了不寻常的起始密码子CAA，COX1、COX2、ND4和CYTB基因以不完整的终止密码子T结束，ND5基因以异常的终止密码子ATT结束。在位于控制区的线粒体基因组中鉴定出一个微卫星（C）。系统发育树显示，首先与聚类，然后与和一起聚类。
