The complete mitochondrial genome of the Xizang hot-spring snake, Wall, 1907 (Reptilia, colubridae).

The Xizang hot-spring snake, (Reptilia, Colubridae), is a relict species of the family Colubridae, which is known only from Tibet, China. In this study, we report the complete mitochondrial genome of this species. The total length of the genome is 17,385 bp, and comprises 13 protein-coding genes, 22 tRNA genes, 2 rRNA genes, and 2 control regions. The total base composition is 32.5% for A, 23.8% for T, 13.5% for G, and 30.2% for C. The phylogenetic tree with 13 protein-coding genes (PCGs) of . together with 12 other closely related species belonging to the family Colubridae was built, in order to prove the validity of the mitogenome of . .
