Diagnosis Test large, discoidal, proloculus and flexostyle followed by planispiral and involute early stage, producing a thickened central part of the test, chambers rapidly increasing in breadth so that the test becomes flabelliform, reniform, and finally discoidal with annular chambers, interior subdivided by two sets of radial septula or intradermal plates that project inward from the lateral faces of the chambers toward the rows of apertures, partitions may be discontinuous and resemble pillars that fuse at the base with adjacent pillars or partitions may be nearly continuous across the chamber, leaving open only the small foramina between opposing chamberlets; wall calcareous, porcelaneous; aperture of two or three rows of multiple pores in a median groove on the truncate apertural face, each opening bordered by a lip; mature tests have six to ten distinctly broader cyclic chambers with larger chamberlets, formed during a short period of time to serve as reproduction chambers for multiple fission, the brood chambers being partially destroyed during the release of the young embryos; symbiotic algae present in the inner chambers of the vegetative test and are provided to the young embryos at the time of reproduction. Oligocene to Holocene; Atlantic; Caribbean; Gulf of Mexico. (Loeblich & Tappan, 1987, Foraminiferal Genera and Their Classification) [details]
