On the planopilumnidae Serène, 1984 (crustacea: brachyura: pseudozioidea), with diagnoses of two new pilumnoid genera for species previously assigned to Planopilumnus Balss, 1933

Abstract

The taxonomy of the planopilumnid Planopilumnus Balss, 1933 (type species Pilumnus spongiosus Nobili, 1905) (Pseudozioidea), is revised. A junior synonym, Rathbunaria Ward, 1933 (type species Rathbunaria sculptissima Wa r d, 1933)), is resurrected. Five species, Pilumnus labyrinthicus Miers, 1884, Pilumnus vermiculatus A. Milne-Edwards, 1873, Pilumnus penicillatus Gordon, 1930, Planopilumnus minabensis Sakai, 1969, and Planopilumnus pygmaeus Takeda, 1977, which have been described in or transferred to Planopilumnus, are here shown to be pilumnids (Pilumnoidea). Two new genera, Vellumnus and Colerolumnus, are established to accommodate these species. Copyright © 2010 Magnolia Press.
