Diagnosis Test in a flat trochospiral coil, spiral side may be partially evolute or involute, about five to eight somewhat inflated chambers in the final whorl, sutures depressed, radial, and gently curved, umbilical side concave, flat, or slightly convex, umbilicus closed, chambers with large umbilical flaps projecting backward and toward the umbilical region, successive flaps imbricated and resulting in a stellate umbilical pattern, periphery broadly rounded, peripheral outline slightly lobulate; wall calcareous, thin, hyaline, perforate, optical character not described; aperture an interiomarginal and equatorial arch, continuing from the periphery to the umbilicus and bordered by a narrow lip that expands at the umbilical end to form the stellate flaps, aperture continues beneath and along the back side of the flap to a small sutural opening, the sutural openings remain as relict apertures adjacent to the flaps of earlier chambers. L. Cretaceous (Albian) to U. Cretaceous (Turonian); cosmopolitan. (Loeblich & Tappan, 1987, Foraminiferal Genera and Their Classification) [details]
