Diagnosis Test planoconvex, low trochospiral, circular in outline, chambers very broad, low, and crescentic and sutures strongly oblique, slightly curved, and elevated on the convex spiral side, sutures curved and slightly depressed on the flattened to concave umbilical side, with triangular umbilical flap or folium from each chamber surrounding the small open umbilicus and forming small foliar chamberlets, periphery subacute, carinate; wall calcareous, hyaline, translucent, spiral side very finely perforate but perforations imperceptible on the umbilical side, surface smooth other than the elevated sutures and keel on the spiral side; primary aperture interiomarginal, extraumbilical, anterior to the folium, with secondary sutural apertures at the posterior side of the folium. Holocene; Caribbean; E. Pacific: off Galapagos Islands. (Loeblich & Tappan, 1987, Foraminiferal Genera and Their Classification) [details]
