Description Test biserially coiled. Initially streptospiral followed by a whorl expanding rapidly. Because of the coiling the shape of the chambers is very variable in sections. Sutures indistinct. No supplementary deposits. Aperture terminal cribrate. Wall differentiated with a tectum and an inner coarse layer with calcareous agglutinate.
Occurrence. Tournaisian–Visean; very poorly known but eventually cosmopolitan.

Diagnosis Test biserial, with planispirally enrolled plane of biseriality or may uncoil in later stage; wall calcareous, microgranular, may have more than one layer; aperture at inner border of apertural face. L. Carboniferous (Tournaisian) to U. Permian (Djulfian). (Loeblich & Tappan, 1987, Foraminiferal Genera and Their Classification) [details]
