Stomatopod mandibles and raptorial claws and fourteen species of decapods including Paradorippe sp. cf. P. granulata (de Haan, 1841), Hiplyra platycheir (de Haan, 1841), Myra sp. cf. M. celeries G alil, 2001, Halimede fragifer (de Haan, 1835), Eucrate crenata (de Haan, 1835) and Entricoplax vestita (de Haan, 1833) are described from the upper Pleistocene Ogushi Formation in Amakusa City, Kumamoto Prefecture, Kyushu, Japan. Alpheidae gen. et sp. indet. is abundant and Eucrate crenataand Entricoplax vestita are common in the decapod fauna of the Ogushi Formation. The occurrence of these species suggests that the Ogushi Formation was deposited as muddy bottom sediment in shallow marine water. Euplax leptophthalmus H. Milnee Edwards, 1852, a rare macrophthalmine crab is first reported as a fossil from Kyushu.
