Abstract
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.
Highlights
The praying mantis comprises up to 2,300 species having diversified morphological and ecological characteristics
Many studies mainly focused on their biological properties, like the distribution, taxonomy, captive breeding behavior and the foodstuffs applications [3, 4]
Four new mitogenomes were described from different families (Amorphoscelidae, Photinaidae and Deroplatyidae), and a relative analysis of all available mitogenomes was conducted. These studies embodied a comprehensive analysis to elucidate the characteristics of protein-coding genes (PCGs), structural features in transfer RNAs and ribosomal RNAs, the rate of evolution of PCGs, and the phylogenetic interrelation of these species based on 35 concatenated mitochondrial genes
Summary
The praying mantis comprises up to 2,300 species having diversified morphological and ecological characteristics. The phylogenetic relationships of Amorphoscelidae, Photinaidae and Deroplatyidae are in doubt in the latest taxonomic system These four species belong to three families and inhabit quite different niches. Four new mitogenomes were described from different families (Amorphoscelidae, Photinaidae and Deroplatyidae), and a relative analysis of all available mitogenomes was conducted. These studies embodied a comprehensive analysis to elucidate the characteristics of protein-coding genes (PCGs), structural features in transfer RNAs (tRNAs) and ribosomal RNAs (rRNAs), the rate of evolution of PCGs, and the phylogenetic interrelation of these species based on 35 concatenated mitochondrial genes. The results will lay the foundation for the study of Amorphoscelidae, Photinaidae and Deroplatyidae in the latest taxonomic system
