Diagnosis Test large, up to a maximum of 34 mm in length, early stage of the microspheric generation trochospirally enrolled, later uncoiling and rectilinear to branching, rectilinear chambers being 1.5 mm to 3 mm wide, megalospheric tests lack the coil and are wholly uniserial; wall of early trochospiral stage alveolar, that of later uniserial stage with three layers, an outer coarsely agglutinated layer of large quartz grains held in a minimum of acid resistant cement, a median layer pierced by canaliculi that are perpendicular to the wall surface and branch outward to give rise to smaller second order canaliculi, and an inner smooth homogeneous calcareous lamella that covers the chamber cavity; aperture an interiomarginal slit in the early enrolled stage, terminal and cribrate in the later rectilinear stage. L. Cretaceous (M. Albian) to U. Cretaceous (Cenomanian to L. Turonian); Czechoslovakia; NW Germany. (Loeblich & Tappan, 1987, Foraminiferal Genera and Their Classification) [details]
