The complete mitochondrial genome of Pseudoxenodon stejnegeri (Squamata: Colubridae: Pseudoxenodontinae) and its phylogeny

The mitochondrial genome sequence of Pseudoxenodon stejnegeri (Squamata: Colubridae: Pseudoxenodontinae) from Taishun County, Zhejiang Province, China, which is 18,475 bp in length and contains 25 tRNAs (including extra two tRNA-Tyr genes and extra one tRNA-Met gene), two rRNAs, 13 protein-coding genes and two identical control regions. The overall AT content of the mitogenome is 59.6% (A = 32.6%, T = 27%, C = 27%, G = 13.4%). In BI and ML phylogenetic analyses, the monophyly of the family Colubridae was well supported and P. stejnegeri was a basal clade of Colubridae.
