Complete mitochondrial genome of Rhynchocypris cf. lagowskii (Cypriniformes: Cyprinidae).

Rhynchocypris lagowskii sensu lato (Cypriniformes: Cyprinidae) has been revealed as a species complex including two species, i.e. R. lagowskii sensu stricto and a cryptic species R. cf. lagowskii. We determined the first complete mitochondrial genome (mitogenome) of R. cf. lagowskii by comparing with a published mitogenome of R. lagowskii sensu stricto. The two species displayed similar pattern of mitochondrial gene arrangements and similar base compositions of the heavy strain with a bias in the A+T content. There were the nucleotide sequence similarity of 91.8% for mitogenomes and pairwise p-distance of 6.9% for COI genes between R. cf. lagowskii and R. lagowskii sensu stricto and these results supported the two species as different species.
