Two new species of decapod crustacean, Hoploparia miyamotoi (Astacidea : Nephropidae) and Callianassa masanorii (Thalassinidea : Callianassidae), are described from the Upper Cretaceous lzumi Group of Osaka and Hyogo Prefectures, Japan. H. miyamotoi represents the first record for the genus from Cretaceous deposits of Japan and C. masanorii is the second of a callianassid known from the Japanese Cretaceous. The occurrence of H. miyamotoi extends the known geographic range of Hoploparia to the west side of the North Pacific.
