Abstract
To investigate the genetic differentiation between the Bonin (Ogasawara) Islands' freshwater goby Rhinogobius sp. Bonin Island (BI) form (Ogasawara-yoshinobori) and the Japan–Ryukyu Archipelago relatives, the mitochondrial DNA (mtDNA) phylogeny of Japanese Rhinogobius species was inferred from partial nucleotide sequences of the mitochondrial NADH dehydrogenase 5 subunit (ND5) gene (945 bp). The resultant tree showed that the Bonin Islands group separated first from the other Japanese lineage, and a test calculation indicated the divergence date to be approximately 3 million years BP. Although it is necessary to use a more reliable estimate to confirm the divergence date, Rhinogobius sp. BI has retained its mtDNA lineage in the islands for millions of years.
