Complete mitochondrial genome of Vanmanenia hainanensis (Cypriniformes: Gastromyzontidae)

Vanmanenia hainanensis Chen & Zheng 1980 is endemic to Hainan Island, China. The complete mitogenome of the species was sequenced in this study. It was 16,555 bp in length, containing 13 protein-coding genes (PCGs), 22 tRNA genes, 2 rRNA genes, and 1 control region. The base composition was 29.5% A, 25.4% T, 16.7% G, and 28.4% C. All genes were encoded on the H-strand except for ND6 and 8 tRNA genes, located on the l-strand. Phylogenetic analysis based on 13 protein-coding genes indicated that the genus Vanmanenia did not form monophyly and it had the closest relationship with Formosania. This study aimed at providing useful genetic information for future studies on taxonomy, phylogeny, and evolution of Vanmanenia species.
