Diagnosis Test planispirally or streptospirally coiled and may uncoil in the later stage; embryonal apparatus simple or quinqueloculine, proloculus of megalospheric generation may be followed by flexostyle; test with central thickening pierced by canals and bordered by subepidermal lamellae that attach to it, part of the distal face of the preceding chamber may be free and form a preseptal area that is crossed by irregularly spaced pillars extending from the underlying central thickening to the internal surface of the overlying septum, the pillars intercalated both between the apertures of the final chamber face and between the openings of the central thickening; aperture multiple, on the final chamber face. U. Cretaceous (Cenomanian to Maastrichtian), ?L. Eocene, ?Holocene. (Loeblich & Tappan, 1987, Foraminiferal Genera and Their Classification) [details]
