Diagnosis Test ovate to circular in outline, planoconvex, trochospiral, with a slight tendency to uncoil, so that part of earlier whorls may be visible centrally on both sides, spiral side convex, with broad low chambers enlarging rapidly as added and sutures curved and depressed, umbilical side flattened, chambers lunate, each with a projecting semicircular umbilical flap or folium, posterior end of the folium of earlier chambers leaving an indentation in the sutures, periphery carinate; wall calcareous, finely perforate, surface smooth; primary aperture an interiomarginal arch at the periphery, with a smaller secondary opening at the posterior end of the folium. Miocene to Holocene; cosmopolitan. (Loeblich & Tappan, 1987, Foraminiferal Genera and Their Classification) [details]
