Description Description: Test ovoid, rarely lenticular, small to moderate in size. Proloculus spherical, relatively wide, followed by an undivided tubular chamber. Initial whorls streptospiral. Terminal whorls aligned to planispiral, oscillating or subsygmoidal, involute with one or two last whorls evolute. Lumen of the chamber at concavus stage or subogival (in the Type species). Wall porcelaneous, probably thin, unilamellar at the periphery and thicker, multilamellar in the axial regions. Aperture terminal, simple.
Range and distribution: Rare in Kungurian (late Leonardian) beds of New Mexico. Early Permian of Japan. Late early Permian of Bashkorotostan (Russia). Middle-late Permian of Tethys and Japan.
