Diagnosis Test trochospiral, nearly equally biconvex, all of the two to three slowly enlarging whorls visible on the spiral side, sutures limbate, straight to curved, bending slightly backward toward the periphery, only the fourteen to sixteen chambers of the final whorl visible on the umbilical side, sutures deeply incised with elevated margins that may be weakly feathered and finely pustulose, leaving open intraseptal spaces that later are transformed into tubular passages to successive whorls of the spiral canal, chamber lumen connected to canal system by an opening from the umbilical chamber extension that leads into vertical intraseptal canals, umbilicus with large umbilical plug having few or no vertical canals but may be subdivided in larger microspheric individuals, umbilical plug surrounded by an umbilical fissure that becomes a simple spiral canal, periphery weakly carinate in early part of last whorl, rounded in later chambers; wall calcareous, finely perforate, smooth except for the imperforate sutural margins, apertural face imperforate; primary aperture a small interiomarginal slit bordered by an imperforate lip that extends into the umbilicus and partly covers the spiral fissure. Holocene; Red Sea: Gulf of Elat; Indian Ocean. (Loeblich & Tappan, 1987, Foraminiferal Genera and Their Classification) [details]
