Diagnosis Test small, up to 0.25 mm in diameter, low to high trochospiral coil of about four whorls, biconvex, about five to six chambers per whorl, spiral side evolute but final whorl may show a tendency to overlap that preceding, umbilical side involute, chambers inflated, enlarging rapidly as added, periphery broadly rounded; wall calcareous, optically granular, very finely perforate, surface smooth; aperture an elongate slit at the base of the apertural face but with a bordering lip both above and below. Pliocene (Plaisancian) to Pleistocene; Indonesia; India; Arabian Sea. (Loeblich & Tappan, 1987, Foraminiferal Genera and Their Classification) [details]
