Diagnosis Test lenticular, trochospirally enrolled, final one to few chambers tending to uncoil, chambers enlarging rapidly as added, about seven or eight in the final whorl, sutures slightly depressed, curved, periphery carinate; wall ¥ calcareous, whether calcite or aragonite not indicated, surface smooth; aperture beginning as a low arch against the previous suture on the umbilical side, continuing as a slit to the center of the apertural face, the umbilical part of the aperture being closed by a porous plate that leaves only a rounded to oval areal opening in the center of the septal face, porous plate present in all chambers, short, narrow, and curved with a free margin and approximately parallel to the periphery. U. Jurassic (Tithonian) to L. Cretaceous (Valanginian); USSR: Crimea, Azerbaydzhan. (Loeblich & Tappan, 1987, Foraminiferal Genera and Their Classification) [details]
