Diagnosis Test low trochospiral, lenticular and inequally biconvex, may be bi-involute or partially evolute on the spiral side, chambers numerous, broad, and low, strongly curved back at the periphery to form chamber prolongations, interior of all chambers with primarily formed toothplate that extends from the apertural face to about the middle of the previous septum and almost completely divides the chamber lumen, contact of the toothplate with the wall of the umbilical side producing a stellate pattern like that of Asterigerina although commonly more irregular due to the twisting of the toothplate, distinct umbilical plug present, periphery angular to carinate; wall calcareous, optically radial, finely perforate, surface smooth other than the papillae in the apertural region; aperture an interiomarginal slit on the umbilical side, bordered by a lip, those of preceding chambers serving as intercameral foramina, surface of the preceding whorl just beneath the aperture covered with fine papillae or rugae oriented in the direction of growth. Eocene to Holocene; cosmopolitan. (Loeblich & Tappan, 1987, Foraminiferal Genera and Their Classification) [details]
