Complete mitochondrial genome of the Korean Clawed Salamander <i>Onychodactylus koreanus</i> Min, Poyarkov &amp; Vieites, 2012 (Caudata: Hynobiidae)

We report the complete mitochondrial genome of the Korean Clawed Salamander (<i>Onychodactylus koreanus</i>), endemic to the Korean Peninsula. The 16,445 bp mitogenome, assembled from Illumina HiSeq data, contains 37 genes (13 PCGs, 22 tRNAs and 2 rRNAs) plus the control region and has an A + T content of 68.6%. Phylogenetic analysis confirms it is a distinct lineage within <i>Onychodactylus</i>, closely related to <i>O. fischeri</i> and <i>O. zhaoermii</i>. These findings enhance our understanding of Hynobiidae diversity and evolution.
