Comparative Analysis of Mitogenomes among Five Species of (Orthoptera: Acridoidea: Pamphagidae) and Their Phylogenetic and Taxonomic Implications.

Mitogenomes have been widely used for exploring phylogenetic analysis and taxonomic diagnosis. In this study, the complete mitogenomes of five species of were sequenced, annotated and analyzed. Then, combined with other seven mitogenomes of and four of Pamphagidae, the phylogenetic relationships were reconstructed by maximum likelihood (ML) and Bayesian (BI) methods based on PCGs+rRNAs. The sizes of the five complete mitogenomes are 15,656 bp, 15,657 bp, 15,661 bp, 15,661 bp and 15,666 bp. The nucleotide composition of mitogenomes is biased toward A+T. All tRNAs could be folded into the typical clover-leaf structure, except that tRNA Ser (AGN) lacked a dihydrouridine (DHU) arm. The phylogenetic relationships of species based on mitogenome data revealed a general pattern of wing evolution from long wing to increasingly shortened wing.
