Diagnosis Test large, microspheric test apparently cornuspirine at first, then planispiral and involute to pseudoevolute, chambers strongly curved and septa oblique, later flabelliform, and finally evolute and cyclic, resulting in a discoidal, flattened, and biconcave test, megalospheric generation with large spherical proloculus, chambers subdivided by short interseptal septula that are perpendicular to the septa and to the lateral walls and do not reach the center of the chambers, those of successive chambers aligned, central area of chambers with similarly aligned interseptal buttresses, of crescentic transverse section in the midregion but nearly circular in section adjacent to the septa; wall calcareous, microgranular, imperforate, probably originally porcelaneous; aperture of numerous rounded pores on the central part of the apertural face in the area of the interseptal buttresses. U. Cretaceous (U. Cenomanian to L. Turonian); Iran; Israel. (Loeblich & Tappan, 1987, Foraminiferal Genera and Their Classification) [details]
