Abstract
The taxonomy and systematics of Phoxinus (Cypriniformes: Cyprinidae) is still not well-resolved. In this study, we determined the first complete mitochondrial genome (mitogenome) of Phoxinus tumensis. The mitogenome was 17,050 bp in length, including 13 protein-coding genes, 22 transfer RNA genes, 2 ribosomal RNA genes and 1 control region. All genes were encoded on the heavy strain except for ND6 and eight tRNA genes. The overall base composition of the heavy strain was 27.9% for A, 25.5% for C, 28.4% for T and 18.2% for G. The control region was revealed to contain tandem repeats. The mitogenome data of P. tumensis should contribute to clarify the systematics of Phoxinus fishes.
