The complete mitochondrial genome (mitogenome) of Danio myersi (Teleostei: Cypriniformes: Cyprinidae) has been sequenced, and it is a circular molecule of 16,565 bp in length and contains the typical complement of 13 protein-coding genes, 2 ribosomal RNA genes, 22 transfer RNA genes and 12 non-coding regions. The order and orientation of the genes are identical to the typical arrangement in vertebrates, and most of the genes were encoded on the H-strand except for ND6 and eight tRNA genes. The AT content of the overall base composition of H-strand is 63.4% (T, 26.8%; C, 25.3%; A, 31.6%; G, 16.4%) and the length of control region is 925 bp with 65.5% AT content. The mitogenome sequenced in the present study will be an important step forward in completely resolving phylogenetic relationships of the subfamily Danioninae in the future.
