Abyssotherma pacifica, n.gen., n.sp., a Recent remaneicid (Foraminiferida, Remaneicacea) from the East Pacific Rise


Journal Article

A new Recent remaneicid, Abyssotherma pacifica, occurs in recruitment arrays placed in the vicinity of deep-sea (2600 m) hydrothermal springs in the East Pacific. It has quite a large (d.500-1200 μm) watchglass-shaped test, characterized by elongate ridges on the sutures of the spiral side, asymmetric and mushroom-shaped chambers on the umbilical side and an interior subdivided by secondary septa. A close homeomorph of the shallow, brackish-water species Bruneica clypea Bronnimann, Keij and Zaninetti, it differs in possessing two apertures per chamber in contrast to the single interiomarginal aperture of Bruneica. -Authors
