Two new brachyurans from the Miocene and Pleistocene deposits of Ishikawa Prefecture are reported. Macrocheira sp. (Macrocheiridae) is the first recorded from the Middle Miocene (Langhian) Sekinobana Formation. Euclosiana obtusifrons (De Haan), a leucosiid crab from the Lower Pleistocene (Calabrian) Onma Formation is the oldest fossil record in Japan. The carapace of E. obtusifrons has exceptionally preserved traces of color spots.
