Diagnosis Test free, lenticular to inequally biconvex, numerous chambers, as many as seventeen in the final whorl, trochospirally enrolled and with a tendency to uncoil in the final stage, periphery subacute, sutures strongly oblique on spiral side, gently curved and subradial on umbilical side; wall imperforate, nonlamellar, of microgranular calcite, probably agglutinated; aperture in early stage arises near umbilicus, is elongated toward the periphery where it curves to parallel the margin as in Nezzazata, finally becoming an areal slit that lies in a depression of the apertural face, the depression reflecting the position of an internal apertural toothplate situated approximately in the median plane of the chamber cavity and branching before attaching to the previous septum at one or two places adjacent to the previous aperture. U. Cretaceous (Cenomanian); Lebanon; Israel; Iran. (Loeblich & Tappan, 1987, Foraminiferal Genera and Their Classification) [details]
