Diagnosis Test trochospiral, planoconvex, spiral side strongly convex, early whorls with up to seven chambers, then reduced to fewer chambers per whorl, with about three to three and a half crescentic and rapidly enlarging chambers in the final whorl, final chamber occupying about one-half the umbilical side, sutures oblique, thickened, and elevated on the spiral side, umbilical side flat to slightly concave, involute, sutures nearly radial, depressed and slightly curved, periphery angular, carinate; wall of calcite, spiral side coarsely perforate, umbilical side imperforate, with small pustules just above the aperture on the final chamber; aperture a strongly curved slit arching from the umbilicus toward the periphery and giving the appearance of a valvelike projection from the base of the chamber against the previous whorl. L. Cretaceous; Argentina. (Loeblich & Tappan, 1987, Foraminiferal Genera and Their Classification) [details]
