Updated Checklist of the Crabs (Crustacea: Decapoda: Brachyura) from the Sea around the Ogasawara Islands, Japan

The known crab species of the Ogasawara (= Bonin) Islands, Tokyo, Japan, are updated, with the literature and localities concerned. In Table 1 are the definitely identified 314 species from the three island groups, Muko-jima (= Keetaa I.), Chichi-jima (= Peel I.) and Haha-jima (= Coffin I.) Groups, and also, 35 species from the southernmost Iwo-jima (= Sulhur I.) Group, and two solitary islands, Nishino-shima (= Rosario) Island and Okino-Torishima (= Parece Veta) Island are listed in Table 2.

Otherwise, in Table 3, the deep-sea 10 species reported from the seamounts off the Ogasawara Islands are listed. Eight of 35 species (in Table 2) and 4 of 10 species (in Table 3) are unrecorded from three main island groups, and thus a total of 326 species are known from the sea around the Ogasawara Islands.
