Diagnosis Test large, rotaloid to operculine, lenticular to flattened and may be slightly asymmetrical, low trochospiral to planispiral coil, septa secondarily doubled, the septal flap enclosing intraseptal canals, umbilical plate present at the base of the alar extension of the chamber on the umbilical side, a low space remaining beneath the umbilical plate as a spiralling canal that communicates with the intraseptal spaces at the base of the septa and connects through small openings to the chamber lumen above the plate, in the larger operculine species folds in the septal flap may produce secondary septa as in Heterostegina, but no marginal cord is present in Daviesina, periphery acute to slightly rounded; wall calcareous, lamellar, very thick, optically radial, perforate except for the imperforate periphery, prominent umbilical pillars, fissures, and vertical canals on both sides of the test, chambers may have radial median ridges and nodes or spiralling chevronlike folds crossing the surface; aperture an interiomarginal slit.
