Paramesotriton aurantius (Caudata: Salamandridae) is a new species that found in southeastern China. Its complete mitochondrial genome (mitogenome) sequence was 16,313 bp in length with with A + T contents of 60.9%, and contained 13 protein-coding genes, 22 tRNA genes, 2 rRNA genes, one control region (D-loop), and one non-coding region. Our molecular tree showed that P. aurantius was positioned near P. hongkongensis, and formed a clade with other Paramesotriton species. The first complete mitogenome sequence of P. aurantius could provided fundamental data for resolving phylogenetic and genetic problems related to genus Paramesotriton.
