dc.description.abstract The new genus <I>Abyssocythere</I> Benson has been erected to receive five new species and one described species of psychrospheric ostracode ranging in age from the Paleocene to the Recent. These species include <I>Abyssocythere casca</I> Benson, new species (Indian Ocean), herein designated the type species, <I>A. pannucea</I> Benson, new species (eastern Pacific), <I>A. japonica</I> Benson, new species (western Pacific), <I>A. atlantica</I> Benson, new species (Atlantic), <I>A. australis</I> (Southern Ocean), and <I>A. trinidadensis</I> (van den Bold) from the Caribbean region. Modern species are typical of the deep-sea floor and are common to depths below 2,000 meters. Fossils have been found in deep-water Paleocene and Miocene strata in Trinidad and in deep-sea cores in Pleistocene sediments. These species are thought to have descended from a yet unknown form of the complex of species assigned to the Cretaceous genus <I>Cythereis</I> (sensu lato). There seems to be an evolution of finer surface features of the carapace and an increase in size throughout the Cenozoic. en
