Diagnosis Test elongate, early chambers subglobular, inflated, and biserially arranged, later chambers more elongate and cuneate to nearly uniserial and rectilinear, the final one or more chambers commonly with an elongate tubulospinelike lateral projection, sutures depressed; wall calcareous, of optically radial calcite, finely perforate; aperture a high interiomarginal arch with narrow bordering lip in the early biserial chambers, in later uniserial chambers the aperture is terminal and the bordering lips merge to form a trough with lateral buttresses that connects directly to the preceding chamber. U. Cretaceous (Turonian to Campanian); USA: Kansas, Colorado, South Dakota; Italy: Sicily; USSR: Azerbaydzhan. (Loeblich & Tappan, 1987, Foraminiferal Genera and Their Classification) [details]
