Deskripsi

Mitogenomes have been widely used for exploring phylogenetic analysis and taxonomic diagnosis. In this study, the complete mitogenomes of five species of <i>Filchnerella</i> were sequenced, annotated and analyzed. Then, combined with other seven mitogenomes of <i>Filchnerella</i> 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 <i>Filchnerella sunanensis</i> 15,656 bp, <i>Filchnerella amplivertica</i> 15,657 bp, <i>Filchnerella nigritibia</i> 15,661 bp, <i>Filchnerella pamphagoides</i> 15,661 bp and <i>Filchnerella dingxiensis</i> 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 <i>Filchnerella</i> species based on mitogenome data revealed a general pattern of wing evolution from long wing to increasingly shortened wing.
