Abstract
The complete mitochondrial genome of Bufo stejnegeri was determined, which was 17 939 bp in length. It consists of 13 protein-coding genes, two rRNA genes, 22 tRNA genes, and one displacement loop (D-loop). The total length of D-loop region is 2533 bp, some tandem repeat units were found in this region. The phylogenetic trees of the 20 species from anura were reconstructed based on complete mtDNA sequences by Bayesian inference and maximum likelihood analyses. The result demonstrated that B. stejnegeri is the most closely related species with other Bufo species.
