Diagnosis Test ovate in outline, flattened, coiled in a low trochospiral, convex spiral side with few rapidly expanding chambers in slightly more than a single whorl and separated by deeply depressed and fissurelike sinuate sutures that are bridged by shell material between the sutural openings, secondary shell material in the umbonal region may obscure the early chambers, umbilical side concave, appearing centrally stellate because of the chamberlets surrounding the umbilical plug that alternate in position with the main chambers, the outer tip of the stellate chamberlets extending along the radial intercameral sutures about half the distance to the angular periphery, peripheral outline lobulate; wall calcareous, optically radial, coarsely perforate; primary aperture a row of interiomarginal openings on the final stellate chamber, primary chamber communicates only with adjacent stellate chambers, secondary multiple sutural openings on the spiral side and along the sutures of both primary chambers and stellate chamberlets on the umbilical side. M. Eocene (Lutetian); India. (Loeblich & Tappan, 1987, Foraminiferal Genera and Their Classification) [details]
