Diagnosis Test trochospiral, planocovex with flattened spiral side and strongly convex umbilical side, chambers rhomboidal in section, the five to seven chambers of the final whorl each with a tubulospine at the proximal end of the chamber and in the plane of the spiral surface, less frequently a tubulospine may arise at the junction of two adjacent chambers, tubulospines increasing in size and length by lamellar growth, so that earlier ones of the final whorl may be larger than the later ones, umbilicus wide, up to one-half the test diameter, sutures radial to curved, depressed to slightly elevated and may be nodose, periphery with a single keel, peripheral outline polygonal; wall calcareous, densely perforate, surface smooth or with pustules covering the surface of early whorls and present along the sutures and peripheral keel; primary aperture umbilical, bordered by a large flat porticus, those of successive chambers imbricated within the umbilicus and may partially fuse. U. Cretaceous (U. Campanian); cosmopolitan. (Loeblich & Tappan, 1987, Foraminiferal Genera and Their Classification) [details]
