Diagnosis Test with spherical to ovate chambers in a high trochospiral coil, about four chambers in the final whorl, sutures radial, deeply depressed, umbilicus wide and deep, periphery rounded, peripheral outline distinctly lobate; wall calcareous, coarsely perforate, surface cancellate, with pore pits and ridges, intersections of the ridges crowned by knoblike pustules or mounds; primary aperture a high interiomarginal, umbilical arch, one or more secondary supplementary apertures may occur on the spiral side of the final whorl. Upper L. Eocene (U. Ypresian) to M. Eocene (L. Lutetian); N. and S. Atlantic; Trinidad. (Loeblich & Tappan, 1987, Foraminiferal Genera and Their Classification) [details]
