Diagnosis

provided by World Register of Marine Species
Test discoidal, thick, megalospheric juvenarium of proloculus, flexostyle and one undivided chamber, then with a few peneroplid chambers, microspheric test peneropline in early stage, later stage of both generations with annular series of small chamberlets that are symmetrical with respect to the equatorial plane, separated by a median annular. passage that appears circular in section, crosswise-oblique stolon system connects chamberlets with two chambers of the preceding series and two chambers of the following series, stolons in a single plane; wall calcareous, porcelaneous, smooth; aperture a single row of openings with protruding rims and with figure 8 outline resulting from the crosswise-oblique stolons, shell material may bridge the narrow part of the opening to form two openings; adult test may produce reproductive chambers. Miocene to Holocene; Atlantic; Caribbean; Pacific; Indian Ocean; Red Sea. (Loeblich & Tappan, 1987, Foraminiferal Genera and Their Classification)
