Diagnosis Test in a low trochospiral coil, planoconvex to biconvex, chambers flat to centrally elevated on the spiral side, commonly inflated and produced around the umbilicus, with a prominent umbilical shoulder surrounding a large solid umbilical plug of clear shell material that may be broken out in preservation, intercameral septa imperforate, doubled secondarily by attachment of a septal flap, sutures gently curved back at the periphery on the spiral side, radial, depressed, and may be fissured on the umbilical side, periphery carinate, peripheral outline lobulate; wall calcareous, perforate, optically radial, surface smooth to pustulose; aperture interiomarginal, extending obliquely up the apertural face, intercameral foramen areal, comma shaped due to the attachment of an imperforate toothplate at the proximal margin of the penultimate chamber foramen, toothplate extending to the distal or outer margin of the aperture, the upper free part being spatulate in form. U. Cretaceous (Coniacian) to Holocene; cosmopolitan. (Loeblich & Tappan, 1987, Foraminiferal Genera and Their Classification) [details]
