Praying mantises are distributed all over the world. Though some Mantodea mitogenomes have been reported, an evolutionary genomic and phylogenetic analysis study lacks the latest taxonomic system. In the present study, four new mitogenomes were sequenced and annotated. Deroplatys truncate, D. lobate, Amorphoscelis chinensis and Macromantis sp. belong to Deroplatyidae, Amorphoscelidae and Photinaidae family, respectively. Our results indicated that the ATP8 gene may be lost in D. truncate and D. lobata mt genome, and four tRNA genes have not been found in D. truncate, D. lobata and Macromantis sp. A dN/dS pair analysis was conducted and it was found that all genes have evolved under purifying selection. Furthermore, we tested the phylogenetic relationships between the eight families of the Mantodea, including 35 species of praying Mantis. Based on the complete mitochondrial genome data, it was also suggested as sister to Deroplatyidae + Mantidae, Metallyticus sp., the only representative of Metallyticidae, is sister to the remaining mantises. Our results support the taxonomic system of Schwarz and Roy and are consistent with previous studies.
螳螂分布于世界各地。虽然已经报道了一些 Mantodea 线粒体基因组，但缺乏最新的分类系统的进化基因组和系统发育分析研究。在本研究中，我们测序并注释了四个新的线粒体基因组。截胸大刀螳、宽纹大刀螳、中华大刀螳和 Macromantis sp. 分别属于刀螳科、螳科和光肩星花螳科。我们的结果表明，ATP8 基因可能在 D. truncate 和 D. lobata mt 基因组中丢失，而 D. truncate、D. lobata 和 Macromantis sp. 中则未发现四个 tRNA 基因。我们进行了 dN/dS 对分析，发现所有基因都在纯化选择下进化。此外，我们还测试了 Mantodea 的 8 个科（包括 35 种螳螂）之间的系统发育关系。基于完整的线粒体基因组数据，它也被认为与刀螳科和螳科具有姐妹关系，而唯一代表金螳科的 Metallyticus sp. 与其余的螳螂具有姐妹关系。我们的结果支持 Schwarz 和 Roy 的分类系统，与之前的研究一致。
