Diagnosis Test stellate, with five to seven irregular radial ridges, up to 7 mm in diameter, thickwalled embryo with globular protoconch and larger embracing deuteroconch, followed by about six thin-walled nepionic chambers that gradually increase in length and develop secondary radial partitions as in Heterostegina, finally becoming cyclic as in Cycloclypeus, chamberlets of successive cycles alternating in position, median layer of chambers increasing very slowly in thickness toward the periphery, lateral layers thicker at the center of the test, thinning toward the periphery, and may have pillars that appear as numerous pustules at the surface. L. Miocene (Burdigalian) to M. Miocene (Vindobonian); Java; Borneo. (Loeblich & Tappan, 1987, Foraminiferal Genera and Their Classification) [details]
