Diagnosis Embryo consists of protoconch and deuteroconch surrounded by a thickened wall, may have one or more early postembryonic chambers with single basal aperture, hence producing a single much reduced spire, later chambers then have a second retrovert aperture or the earliest postembryonic chambers may immediately have two apertures, all biapertural chambers then producing two new chambers and eventually a cyclic growth stage, arcuate equatorial chambers with only radial stolons, lateral chambers present. Upper M. Eocene; Mexico; West Indies. (Loeblich & Tappan, 1987, Foraminiferal Genera and Their Classification) [details]
