Diagnosis Test large, flattened, may be involute but more commonly evolute, with rapidly enlarging whorls and numerous chambers per whorl, sutures radial, slightly curved back at the periphery, imperforate and may be elevated, septa simple, septal flap unfolded, no trabeculae, marginal cord thick, canal system with elongate meshes in the marginal canal, intraseptal canals join the lateral canals of the lateral walls that in turn connect the spiral canal at the base of the whorl to the bundle of marginal canals at the periphery, simple, narrow, and short sutural canals along the lateral canals may be forked or ramified and form rows of alternating openings along the imperforate septal suture, stolons simple, radial, or oblique and irregularly distributed; wall calcareous, finely perforate, surface may be smooth, have pustules reflecting interseptal pillars, or have a reticulate pattern due to elevated or pillar-bearing spiral and radial sutures; intercameral foramen formed by resorption at the base of the imperforate septal face, apertural face with longitudinal grooves that are continuous along the periphery to the preceding septum. M. Paleocene to Holocene; cosmopolitan tropical and subtropical. (Loeblich & Tappan, 1987, Foraminiferal Genera and Their Classification) [details]
