Diagnosis Test trochospiral, about two to two and a half whorls of globular, rapidly enlarging chambers, commonly four to five but rarely up to seven in the final whorl, umbilicus open, periphery rounded but a large pointed spine arising from the midpoint of each chamber results in a stellate peripheral test outline; wall calcareous, optically radial, finely perforate, surface smooth to reticulate, with a single large spine on the spiral side of each chamber, umbilical side with striae radiating from the umbilicus and separating rows of fine granules; aperture interiomarginal, umbilical to slightly extraumbilical; sexual reproduction plastogamic and paired individuals common. M. Eocene (Lutetian) to Holocene; Austria; Western Australia; Timor Sea: Sahul Shelf; Yellow Sea; India. (Loeblich & Tappan, 1987, Foraminiferal Genera and Their Classification) [details]
