Mitogenome of a monotypic genus, Oliotius Kottelat, 2013 (Cypriniformes: Cyprinidae): Genomic characterization and phylogenetic position.

We examined the evolutionary status of the genus Oliotius Kottelat, 2013, clarified the mitogenome structure of Smiliogastrinae, and analyzed its phylogenetic information to provide a reference for the taxonomy, evolutionary genetics, and germplasm identification of Smiliogastrinae. Using next-generation sequencing, the complete mitogenome sequence of the monotypic species Oliotius oligolepis was obtained, annotated, and characterized. The mitogenomic sequences of Smiliogastrinae fish were compared and analyzed, and a phylogenetic tree was constructed.
