Diagnosis Test planispirally enrolled, involute, biumbilicate, periphery acutely angled, with numerous small nummulitoid chambers per whorl, spire expanding rapidly, the inner part of each whorl, where it is of maximum thickness and that was described originally as a second spire, is seen in section to be completely filled with agglutinated matter; wall agglutinated, imperforate, nonalveolar; aperture interiomarginal, in equatorial section the intercameral foramina leave a distinct gap between the inner ends of the septa and the outer part of the densely filled area, aperture suggested to become areal in the adult stage. U. Cretaceous (Cenomanian); Israel; Iraq. (Loeblich & Tappan, 1987, Foraminiferal Genera and Their Classification) [details]
