Diagnosis Early stage triserial or biserial, later may be reduced to uniserial with cuneate chambers or with biseriality reflected internally; wall calcareous, perforate, lamellar, optically granular, hyaline oblique in structure; aperture a subterminal straight to curved slit, eccentric and partially covered by a projecting hood or may be terminal and cribrate; internal siphon extends from the aperture to the previous chamber foramen, those of earlier chambers remaining as a columellalike structure that may reflect the ancestral biseriality even within the uniserial chambers. L. Cretaceous (Aptian) to Holocene. (Loeblich & Tappan, 1987, Foraminiferal Genera and Their Classification) [details]
