Diagnosis Test planispiral, evolute to involute, lenticular, discoidal to globular; chambers numerous and may be subdivided into chamberlets, equatorial chambers and lateral chamberlets may be differentiated, and later chambers may be added in annular series; septal flap present as in Rotaliacea; subsutural canals, spiral marginal cord and spiral canal system present in early forms but modified in later ones or replaced by intraseptal canals in advanced forms. Paleocene to Holocene. (Loeblich & Tappan, 1987, Foraminiferal Genera and Their Classification) [details]
