Diagnosis Test trochospiral, biconvex, spiral side evolute but early part may be obscured by umbonal shell thickening, chambers broader than high and sutures curved and limbate, sutures on umbilical side more radial and depressed, prominent chamberlets in the central part of the test result from an internal partition that extends from the aperture across the umbilical side of the chambers to attach to the previous septum but does not reach the spiral side of the test, periphery broadly rounded; wall calcareous, with proteinaceous inner layer, coarsely perforate, wall of umbilical chamberlets thin; aperture interiomarginal, a loop extending up the apertural face on the periphery, the lower part closed secondarily so that the intercameral foramen is wholly areal. Miocene to Holocene; Venezuela; USA: Louisiana; Dominican Republic; China: Shandong Province. (Loeblich & Tappan, 1987, Foraminiferal Genera and Their Classification) [details]
