Diagnosis Test lenticular, laterally compressed, periphery narrowly rounded, up to 2.2 mm in diameter, involute, but may be slightly depressed centrally, chambers numerous, up to twenty-five in the final whorl, low and wide, increasing rapidly in breadth as added to result in a flaring test, septa strongly arched, interior of chambers subdivided by numerous complete vertical septula, up to sixty or more in the final chambers, commonly aligned from chamber to chamber, secondary septula may be intercalated near the outer walls but do not project into the central region of the chambers and may only cross half the height of the chambers; wall porcelaneous, thin and delicate; aperture consists of numerous areal pores in a row across the base of the apertural face and extending up the center. U. Cretaceous (Campanian to Maastrichtian); Cuba. (Loeblich & Tappan, 1987, Foraminiferal Genera and Their Classification) [details]
