Original description Description: Test is probably attached, small, bichambered, evolute, with pseudotubular second chamber. Coiling is in two planes; initially the second chamber forms two volutions with a slight displacement relative to each other around the proloculus, and then changes the plane of coiling and spirals randomly. Wall is calcareous, single layered, microgranular, and very thin.
Occurrence: USA, New Mexico, Guadalupe Mountains, Dark Canyon, the Tansill Formation; Middle Permian (Capitanian); Italy, southern Apennines, limestone conglomerate of Permian age in the Triassic Monte Facito Formation.
Range: Middle Permian (Capitanian).
