Diagnosis Test low and conical, planoconvex to concavoconvex, trochospiral, with about two and a half gradually enlarging whorls of numerous chambers, about twenty chambers in the final whorl, sutures elevated as narrow irregular ridges and strongly curved back toward the periphery on the convex spiral side, radial and depressed on the flattened umbilical side in the early stage, in larger specimens bending near the periphery, and finally with sutures sharply angled midway between the deep open umbilicus and the acutely angled periphery; wall calcareous, thin, finely perforate, surface finely pustulose on the spiral side and on the earlier chambers of the final whorl on the umbilical side; aperture an elongate interiomarginal slit extending from the periphery nearly to the umbilicus. M. Eocene (U. Lutetian) to L. Miocene (Aquitanian); New Zealand. (Loeblich & Tappan, 1987, Foraminiferal Genera and Their Classification) [details]
