Characterization and phylogenetic analysis of the mitochondrial genome of xanthabraxas hemionata (lepidoptera: Geometridae)

Xanthabraxas hemionata (Guenee, 1858) is a medium-sized and slender-bodied forest pest in China. In this study, we sequenced and analyzed the complete mitochondrial genome (mitogenome) of X. hemionata. This mitogenome was 15,309 bp long and encoded 13 protein-coding genes (PCGs), 22 transfer RNA genes (tRNAs), and 2 ribosomal RNA genes (rRNAs). The gene order was conserved and identical to that of most other previously sequenced Geometridae species. Most of the PCGs of X. hemionata, except for cox1, have the conventional ATN start codon. Except for four genes (cox1, cox2, nad5, and nad4) that end with the incomplete stop codon T-, all other PCGs terminated with the stop codon TAA. Phylogenetic analysis positioned X. hemionata in a well-supported clade with the other Ennominae species. The relationships (Ennominae + (Sterrhinae + Larentiinae)) were supported by Geometridae.
