Diagnosis Test stellate to subdiscoidal, rays may be evident at the surface or only visible in horizontal section, globular megalospheric protoconch partly embraced by larger reniform deuteroconch, followed by two principal auxiliary chambers, other chambers of the first annulus somewhat smaller, microspheric protoconch followed by a short nepionic spiral of arcuate chambers, later chambers in annular series, those of successive annuli alternating in position, equatorial chambers not subdivided into chamberlets, later chambers spatulate and finally rectangular in both generations, the median layer thicker and lateral layers reduced toward the periphery, radial zones formed by elongated equatorial chambers in the median plane separated by zones of smaller chambers in the interrays, commonly five rays present but these may increase by intercalation toward the periphery of larger specimens, lateral chambers present on both sides of the median layer, annular stolons at the proximal side of the equatorial chambers and additional stolons may connect chambers with those of adjacent annuli; radial chamber walls well developed, pillars present, appearing as pustules at the surface where they are surrounded by rosettes of lateral walls. M. Paleocene to U. Eocene; cosmopolitan, tropical and subtropical. (Loeblich & Tappan, 1987, Foraminiferal Genera and Their Classification) [details]
