Diagnosis Test lenticular to discoidal, megalospheric test up to 1.5 mm in diameter, thin-walled proloculus and flexostyle followed by planispiral and involute whorls, rapidly increasing from about twelve chambers in the earliest whorl to twenty or thirty in the next few whorls, rarely may tend to uncoil in the adult, microspheric test larger, may be over 12 mm in diameter, planispiral throughout and chambers never completely annular, interior with radial pillars of triangular section arising from the chamber floor between the apertural foramina to extend about halfway into the chamber, producing small rectangular chamberlets in the lower part of the marginal zone of the chambers, radial pillars of successive chambers aligned, central part of the chambers subdivided by one to three rows of similarly aligned interseptal pillars, sutures weakly depressed; wall calcareous, porcelaneous, relatively thick, surface smooth; intercameral foramina and probably external aperture of rows of small circular pores. U. Cretaceous (Santonian); Peru. (Loeblich & Tappan, 1987, Foraminiferal Genera and Their Classification) [details]
