KARASAWA, Hiroaki  and  KANO, Manabu. A first notice of the goniodromitid crab from the Cenomanian (Upper Cretaceous) cold seep deposits of Hokkaido, Japan, with the redescription of Sabellidromites inflata (Collins and Karasawa, 1993) (Decapoda: Goniodromitidae).

Goniodromites sp. (Brachyura: Dromiacea: Goniodromitidae) is described from the Cenomanian (Upper Cretaceous) cold seep sediment in the Middle Yezo Group of Hokkaido, Japan. This species is the first recognition of the genus and family from the Cretaceous chemosynthetic communities, and represents the second record of a decapod from the fossil chemosynthetic communities in Japan. In addition, Sabellidromites inflata (Collins and Karasawa, 1993), a poorly known goniodromitid crab is redescribed.

Keywords : Decapoda; Brachyura; Goniodromitidae; cold seep; Cretaceous; Japan.
