The complete mitochondrial genome of the praying mantises was characterized in this study. The circular molecule is 15,416 bp in length (GenBank accession no. MN037794), containing 13 protein-coding genes (PCGs), two ribosomal RNA (rRNA) genes, 22 transfer RNA (tRNA) genes. The nucleotide composition is asymmetric (39.5% A, 15.1% C, 9.6% G, 35.8% T), with an overall A + T content of 75.3%. The gene arrangement of is identical to that observed in other praying mantises. Seven PCGs are initiated with typical ATN start codons, Four genes (, nad3, nad4L, and ) begin with TTN, nad1 begin with GTT, and use CTT, as initiation codon. Twelve PCGs stop with complete termination codon TAA and TAG, whereas uses incomplete termination codon (T--). Twenty reading frame overlaps and seven intergenic regions are found in the mitogenome of . The phylogenetic relationships based on 13 PCGs show that clusters closest to the species of Mantidae.
本研究对螳螂的完整线粒体基因组进行了特征分析。该环状分子长度为15416 bp（GenBank登录号：MN037794），包含13个蛋白质编码基因（PCGs）、两个核糖体RNA（rRNA）基因、22个转运RNA（tRNA）基因。核苷酸组成不对称（A占39.5%、C占15.1%、G占9.6%、T占35.8%），A+T总含量为75.3%。其基因排列与其他螳螂中观察到的相同。7个PCGs以典型的ATN起始密码子开始，4个基因（、nad3、nad4L和）以TTN开始，nad1以GTT开始，以CTT作为起始密码子。12个PCGs以完整的终止密码子TAA和TAG结束，而使用不完整的终止密码子（T--）。在的线粒体基因组中发现了20个阅读框重叠和7个基因间隔区。基于13个PCGs的系统发育关系表明，与螳螂科的物种聚类最接近。
