The generic affinities of the Indo-West Pacific species assigned to Rochinia A. Milne-Edwards, 1875 (Crustacea: Brachyura: Majoidea: Epialtidae).

The generic positions of the 29 Indo-West Pacific species currently placed in Rochinia A. Milne-Edwards, 1875, sensu lato, are addressed, in an attempt to establish a more phylogenetically coherent classification for these spider crabs. Twenty-five Indo-West Pacific species are referred to a redefined Samadinia Ng & Richer de Forges, 2013. Three species are transferred to Laubierinia Richer de Forges & Ng, 2009, Pugettia Dana, 1851, and Oxypleurodon Miers, 1885, respectively. Rochinia kagoshimensis (Rathbun, 1932) and a new species from the South China Sea are assigned to a new genus. The generic status of four Atlantic species of Rochinia is also discussed.
