Diagnosis Test ovate to elliptical, laterally compressed, with globular proloculus followed by planispirally enrolled chambers one-half coil in length, coiling involute, in the final stage tending to uncoil and be evolute, chambers widest proximally and tapering distally, the final chamber with long tubular distal portion, terminally expanding at the everted apertural rim; wall calcareous, porcelaneous, perforate, but commonly recrystallized, surface of the final chamber may be transversely wrinkled; aperture terminal, single, with everted rim. U. Triassic (Carnian?, Norian to Rhaetian); Turkey; Italy: Sicily; Yugoslavia. (Loeblich & Tappan, 1987, Foraminiferal Genera and Their Classification) [details]
