Diagnosis Test discoid, flattened, nucleoconch slightly elevated above the general test surface and consists of a globular proloculus and planispirally enrolled narrow tubular undivided second chamber of one and a half whorls, later chambers gradually shortened to about one whorl, early whorls separated by a flat calcareous plate as in Ophthalmidium, later chambers abruptly higher, flaring and closely appressed to form a flabelliform stage, earlier flaring chambers subdivided by three or four vertical partitions but increase in number in later chambers, peneropliform stage followed by more enveloping and finally annular chambers with many partitions arising from the chamber floor but not reaching the chamber roof, leaving a continuous connection just beneath the outer wall, chamberlets connected withthose of the previous and following annular chambers and to the exterior by small slitlike openings, sutures flush to slightly limbate; wall calcareous, imperforate, porcelaneous; aperture a single row of slitlike openings around the periphery, alternating in position with the inner partitions, those of earlier chambers remaining as intercameral foramina. M. Miocene to Holocene; Mediterranean; Atlantic. (Loeblich & Tappan, 1987, Foraminiferal Genera and Their Classification) [details]
