Diagnosis Test planoconvex to inequally biconvex, trochospiral, with about two and a half slowly enlarging whorls, on the evolute and convex spiral side chambers are low and crescentic and sutures thickened and flush, whereas on the involute umbilical side the chambers appear subtriangular and sutures radial and depressed around an umbilical plug, chamber interior simple and undivided, periphery carinate; wall calcareous, hyaline, very finely perforate on the umbilical side, no pores visible on the spiral side at X 3000 magnification; aperture a low interiomarginal extraumbilical slit on the umbilical side, surrounded by a narrow lip that is interrupted only at the umbilical margin, adjacent to a narrow and short umbilical flap or folium, a slight notch in earlier sutures reflecting the posterior end of the folium of successive chambers. Oligocene to Holocene; cosmopolitan. (Loeblich & Tappan, 1987, Foraminiferal Genera and Their Classification) [details]
