Using specimens collected around the distribution border between Platycerus albisomni and P. takakuwai in Utsukushigahara — the Yatsugatake Mountains, and in the area around Mt. Kumotoriyama, we examined male endophallic morphologies and mitochondrial genes. In both species, the geographical borders of morphology and mitochondrial genes were nearly coincident. We inferred that gene flow between the two species was strongly restricted, although hybrids were found. The observed hybrid zone between
