Complete mitochondrial genome of Hynobius dunni (Amphibia, Caudata, Hynobiidae) and its phylogenetic position.

Hynobius dunni is a salamander species of the genus Hynobius endemically distributed in eastern Kyushu in southwestern Japan. In this study, we determined the complete mitochondrial genome sequence and clarified the phylogenetic position of this species. The mitochondrial genome was 16,47 bp in length and encoded 13 protein, 2 ribosomal RNA, and 22 transfer RNA genes. Phylogenetic tree based on 13 protein-coding genes revealed that H. nebulosus were the most closely related species within the Hynobius species. The data identified in this study will be useful for population and conservation genetic studies of Hynobius species.
