Platepistoma Rathbun, 1906 |
| Abstract |
The genus Platepistoma Rathbun, 1906, is reviewed and considered to be valid and not a subgenus of Cancer Linnaeus, 1758. Three new species are described viz. P. nanum, P. kiribatiense and P. seychellense. They are mainly separated on the distinctness of the carapace regions, extent of dorsal granulation of the carapace, and shape of the telson of the male abdomen. The genus is considered to contain seven species, and a key is provided. The name Platepistoma anaglyptum Balss, 1922, is resurrected and the synonymy clarified. Cancer balssii Zarenkov, 1990, is placed in Platepistoma. Cancer (Glebocarcinus) Nations, 1975, is also considered a valid taxon and provisionally allowed to remain as a subgenus of Cancer; it contains at least Cancer oregonensis Rathbun, 1898, and C. amphioetus Rathbun, 1898. Platepistoma is restricted to deeper water, mostly greater than 350 m, in the Indo-West Pacific Oceans, and this is briefly discussed in relation to recent biogeographic theories. |
