The complete mitochondrial genome of Sinotmethis brachypterus Zheng & Xi, 1985, which was collected from the Gansu Province of China, is reported here. It is 15,662 bp in length and contains 72.6% AT. All Sinotmethis brachypterus protein-coding sequences start with a typical ATN codon, excluding cox1 and nad6. The usual termination codon (TAN) and incomplete stop codons (T, TA) were found from 13 protein-coding genes. All tRNA genes could be folded into the typical cloverleaf secondary structure, excluding trnS(AGN) which forms another structure. The sizes of the large and small ribosomal RNA genes are 1320 and 852 bp, respectively. The AT content of the A + T-rich region is 84.2%.
