Original Description
The genus is found in a short period just at the end of the uppermost Maastrichtian.
The extraumbilical aperture may be explained as caused by the small umbilical hollow and seems to be due to a slight torsion of the chambers; in initial chambers the apertures are umbilically placed; as a whole the genus is not unlike Hedbergella, though there are some different characteristics. Parvularugoglobigerina seems to be the atavistic end of the Hedbergella-Rugoglobigerina lineage. The structural features of the test walls in these genera are alike: the walls consist of fine radial crystals.
