Original description: Translated from French. "Diagnosis. - A species characterized by a slight elongation of the chambers, indeed placing this form between two genera, Globigerina and Hastigerinella. "Description: - Test with a globigerinid mode of coiling. The chambers, numbering 5 in the last whorl, are strongly inflated, not compressed and slightly elongate in a radial direction; they are often shifted with regard to a plane perpendicular to the coiling axis. The aperture is protected by an umbilical lip.

Plot of occurrence data:

Dec 2017 - Plotting of Neptune data has been re-enabled on the Mesozoic pages following revision of the age-models in Neptune. The data is, however, still very sparse for the Early Cretaceous
