Diagnosis Test lenticular, protoconch and slightly larger deuteroconch followed by two to three whorls of planispirally enrolled large equitant chambers in the equatorial layer, earliest six to nine chambers with single aperture, later ones also with retrovert aperture, whorls expanding so that smaller secondary chambers are intercalated between them, lateral layers of chambers on both sides but weakly developed in geologically older representatives, pillars present, no distinct roof and floor between equatorial and lateral layers; wall with numerous pores. U. Cretaceous (U. Campanian); Austria; Sweden; Switzerland. (Loeblich & Tappan, 1987, Foraminiferal Genera and Their Classification) [details]
