Diagnosis Test discoidal, flat to concavoconvex, convex side may appear umbonate due to lamellar thickening in the early stage, megalospheric generation with proloculus slightly to completely embraced by second chamber of the biloculine embryo, later chambers in annular series in a single layer, early annular chambers with arched terminal wall, those of later cycles rectangular in form and alternating in position with those of the preceding and subsequent cycles; wall calcareous, coarsely perforate, central region thickened; aperture multiple, consisting of numerous stoloniferous openings. M. Eocene; Cuba. (Loeblich & Tappan, 1987, Foraminiferal Genera and Their Classification) [details]
