Two new species of Longodromitidae, Planoprosopon ogawaense and Planoprosopon sarumaru, are described, based upon examination of the previously known and new specimens of crabs from the Torinosu Group (Upper Jurassic–Lower Cretaceous), Shikoku, Japan. Both species together with goniodromitids from the Torinosu Group (Karasawa and Kato, 2007) and a longodromitid from the Somanakamura Group (Kato et al., 2010) represent the oldest records of Brachyura known from the circum-Pacific realm.
