Abstract
This study determined the complete mitochondrial genome of Formosania galericula (Cypriniformes: Gastromyzontidae) from Zhejiang, China, for the first time. The complete mitochondrial genome of F. galericula was sequenced to be 16,555 bp in length. The genome contained 13 protein-coding genes, 22 transfer RNAs, two ribosomal RNAs, two central non-coding regions (the control region and the origin of light strand replication), identical to most other vertebrates. Phylogenetic analysis highly supported that F. galericula was close to Crossostoma lacustre and the genus Vanmanenia fish. However, F. galericula was not firstly clustered with Formosania chenyiyui but after the genus Vanmanenia fish. These data would explain the evolutionary mechanisms and biogeography of the family Gastromyzontidae and is helpful for the conservation of genetics and stock evaluation for F. galericula.
