The first complete mitochondrial genome of the hawkmoth (Lepidoptera: Sphingidae) and insights into its phylogenetic position.

In this study, we sequenced and analyzed the complete mitogenome of Okamoto, 1924. The complete mitogenome sequence of is circular, 15,662 bp in size and encodes 13 protein-coding genes (PCGs), two ribosomal RNA genes (rRNAs), 22 transfer RNA genes (tRNAs), and a control region (CR). Nucleotide composition is highly biased toward A + T nucleotides (81.2%). Most of 13 PCGs initiate with the standard start codon of ATN, except , which starts with CGA. Phylogenetic analyses were performed using nucleotide sequences. A total of 32 Smerinthinae species were selected. The topology based on mitogenome showed that , , and formed a clade, and this indicated that was a member of genus . was the most closely related to genus on the phylogenetic tree reconstructed by mitogenomes.
