Diagnosis Test lenticular, trochospiral, with few whorls, chambers enlarging rapidly in breadth so that test is somewhat flaring, on the strongly convex spiral side all chambers are visible and the sutures strongly curved and limbate, a hooklike sutural branch midway between the periphery and umbo probably reflecting attachment of an internal partition, only the chambers of the final whorl visible on the umbilical side where the sutures are depressed and radial, periphery acutely angled to carinate; wall calcareous, aragonitic by X-ray determination, surface smooth and polished, with translucent band adjacent to the periphery on the umbilical side; aperture umbilical and interiomarginal, extending in a groove up the apertural face, covered by a plate as the new chamber is added, small areal ovate intercameral foramen produced by resorption a short distance above the base of the septum. U. Eocene (Runagan) to L. Oligocene (Whaingaroan); New Zealand. (Loeblich & Tappan, 1987, Foraminiferal Genera and Their Classification) [details]
