Diagnosis Test circular to subquadrate in outline, globular proloculus and much larger embracing deuteroconch followed by a single ring of large nepionic chambers, smaller equatorial chambers later form a single layer of numerous slightly irregular annuli, very thin and irregular radial walls of equatorial chambers may be complete, incomplete distally, or absent, those of successive annuli aligned, annular stolons at the distal side of the chambers connect those of a single annulus, stolons also present between successive annuli, chamber roofs and floors with pores, fine canals present in annular and radial walls, numerous somewhat irregular layers of lateral chambers on both sides of the equatorial layer, pillars present. L. Eocene to U. Eocene; North America; South America. (Loeblich & Tappan, 1987, Foraminiferal Genera and Their Classification) [details]
