Diagnosis Test up to 12 mm in diameter, thin and lenticular, discoidal to stellate in outline, structure similar to Discocyclina but with distinct rays or ridges formed by proliferation of broad and low lateral chambers that may extend slightly beyond the general periphery, number of rays may increase by intercalation toward the periphery, megalospheric embryo with spherical protoconch nearly surrounded by the larger deuteroconch, later equatorial chambers cyclical and of increasing height as seen in equatorial section, subdivided into chamberlets by radial partitions approximately aligned in successive whorls, pillars may be present along the rays; wall of lateral chambers thin, surface with numerous granules between and upon the elevated ribs, those toward the periphery appearing in concentric circles. M. to U. Eocene; Europe; North America. (Loeblich & Tappan, 1987, Foraminiferal Genera and Their Classification) [details]
