Description Test biserial, entirely planispiral or initially trochospiral, or entirely uncoiled, or trochospiral, becoming planispiral. Wall thin, dark, microgranular, eventually granular with inclusions of clearer carbonate particles, or differentiated into two, three or four layers; nevertheless, this differentiation does not affect all the chambers and/or corresponds to fossil diagenetic features, and is not admitted here as a generic criterion. Endoskeletal folds or partitions lead to the formation of chamberlets. Oral tongue often present, occasionally passing to a siphon. Aperture terminal simple.
Occurrence: Mississippian (latest Tournaisian)–Permian (latest Changhsingian). ?Earliest Triassic. The Pennsylvanian genera are rather cosmopolitan, whereas the Permian ones are restricted to the Tethys and Panthalassa.
