New Cenozoic Deep-Sea Genus, Abyssocythere (Crustacea: Ostracoda: Trachyleberididae), with Descriptions of Five New Species
The new genus Abyssocythere 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 Abyssocythere casca Benson, new species (Indian Ocean), herein designated the type species, A....
