Diagnosis Test discoidal, large, biconcave with thickened periphery, megalospheric test up to 11 mm in diameter; juvenarium formed before release of the embryo from the parent test consists of proloculus, spiral passage, and larger deuteroloculus with numerous pores; microspheric test up to 30 mm in diameter, with small early planispiral and peneropline stage and later cyclic chambers, subdivided by short vertical septula that project inward for a short distance from the flat sides of the test to form a narrow marginal zone, leaving open a wide central passage that contains irregular or incomplete central partitions or pillars, chamber floor of marginal zone offset a half chamber height from that of the median zone, oblique stolons connect the lateral chamberlets to the chambers above and below, larger specimens commonly have a central hole in the test where the thinner-walled early portion is missing, probably due to resorption by the individual, finally the adult produces four to nine higher, cyclic, and undivided reproduction chambers with a coarsely porous outer margin, up to one hundred fifty new embryos may form in the brood chamber and are released by bursting through the coarsely perforate outer wall; wall calcareous, imperforate, porcelaneous, consisting of about 12.5 percent magnesium calcite; aperture of numerous small circular openings randomly scattered over the peripheral wall, and remaining as intercameral pores that diagonally connect successive chambers; endosymbiotic dinoflagellates present. Miocene to Holocene; Pacific and Indian Oceans. (Loeblich & Tappan, 1987, Foraminiferal Genera and Their Classification) [details]
