Abstract

To elucidate the genetic population structure of Pseudogobio esocinus (Cyprinidae) in central Honshu, Japan, we performed phylogeographic analysis based on partial mitochondrial cytochrome b gene sequences. We found not only differentiation of mtDNA lineages between basins (uncorrected p ≈ 2%), presumably associated with uplifting of the Suzuka Mountains in the early Pleistocene, but also more diverged two mtDNA lineages within basins (p ≈ 8%). No evidence of mtDNA introgression from related sympatric species was found. The phylogeographic history of these two lineages should be elucidated by further analysis based on the specimens of P. esocinus from the entire distribution range.
