Coleia uzume sp. nov., a lobster of the polychelidan family Coleiidae, is described from the upper Triassic (Carnian) Nakatsuka Formation of the Mine Group in Yamaguchi Prefecture, southwest Japan. The discovery of C. uzume greatly extends the geologic range for the genus back to the late Triassic. This species represents the first and oldest records of a Triassic decapod in the western Panthalassic realm.
