SYRINGAMMINA CORBICULA SP. NOV. (XENOPHYOPHOREA) FROM THE CAPE VERDE PLATEAU, E. ATLANTIC Susan L. Richardson1 Smithsonian Marine Station at Fort Pierce, 701 Seaway Drive, Fort Pierce, FL 34949 U.S.A. 1 Email: richardson@sms.si.edu A new xenophyophore species, Syringammina corbicula, is described and illustrated from live specimens collected at 3106 m on the Cape Verde Plateau, off West Africa. This species is characterized by its epibenthic habitat and the unique basket-like depressions that rim the periphery of its hemispherically-shaped test of anastomosing, agglutinated tubes. Morphological features of the test and cytoplasm of S. corbicula are described in detail and contrasted with other known xenophyophore species grouped in the genus Syringammina. Laboratory observations of the pseudopodia extruded by live individuals are presented and the potential feeding behavior of S. corbicula is discussed briefly.
