Diagnosis Test biconvex, trochospiral with about two whorls, chambers enlarging rapidly as added, five or six in the final whorl, sutures distinct, radial, and deeply incised, secondarily added sutural-umbilical plates cover the incised sutures and central region on the umbilical side, forming a stellate system of chamberlets, periphery carinate, peripheral outline lobulate; wall calcareous, coarsely perforate, optically radial, stated to be of aragonite as determined by Meigen's reaction but more probably of calcite, surface smooth; aperture an asymmetrical interiomarginal arch, extending from the periphery onto the umbilical side and bordered by a distinct lip. M. Eocene (Lutetian); India: Rajasthan. (Loeblich & Tappan, 1987, Foraminiferal Genera and Their Classification) [details]
