Metapolycope, a New Genus of Bathyal Ostracoda from the Atlantic (Suborder Cladocopina). Smithsonian Contributions to Zoology, Number 225

摘要

Metapolycope, a new genus of Ostracoda, in the suborder Cladocopina, is described from 5 samples collected in the Atlantic Ocean by personnel aboard the Atlantis II and Ingolf at depths of 587-2191 m. Two new species, M. hartmanni and M. microthrix, are described and illustrated. The ontogeny and sexual dimorphism of M. hartmanni are discussed, and a key is given for identifying instars. Keys are also given for identifying genera of the Polycopidae, and species of Metapolycope.
