Is Copytus Skogsberg, 1939 (Crustacea: Ostracoda) a neocytherideid? : with description of a new family and two new species

The genus Copytus Skogsberg, 1939 was erected based on C. caligula, recovered from bottom sediments of the South Georgia Island, Antarctica. However, we propose herein that Skogsberg’s species is a junior synonym of Cytherideis laevata Brady, 1880 also collected from Antarctica and, therefore, Copyt...

Description
Summary:The genus Copytus Skogsberg, 1939 was erected based on C. caligula, recovered from bottom sediments of the South Georgia Island, Antarctica. However, we propose herein that Skogsberg’s species is a junior synonym of Cytherideis laevata Brady, 1880 also collected from Antarctica and, therefore, Copytus laevata (Brady, 1880) becomes the type species. The position of the genus Copytus in the family Neocytherideidae is discussed, and a new family is proposed. In addition, we consider the genus Neocopytus Külköylüoðlu, Colin & Kiliç, 2007 invalid, and some of its species are transferred to Copytus. Finally, two new species of Copytus are herein described, C. cuspidata sp. nov. and C. wuerdigae sp. nov., and their geographic, bathymetric and stratigraphic distributions are discussed.
