Description Diagnosis: Test planispiral, evolute. Proloculus followed by a undivided tubular chamber. Terminal cribrate aperture. Wall brownish, granular, occasionally with a calcareous agglutinate (e.g., Reitlinger, 1950, pl. 1, fig. 8).
Occurrence: Late early Visean to late Serpukhovian, Palaeotethys (including Sumatra (Fontaine & Vachard, 1981) and South China (Wu et al., 2009)) and Urals Province; ?NW Australia (Belford, 1970) or Uviella.
