Extra details from original publication
It resembles Globigerinoides Cushman in having the multiple sutural secondary apertures in addition to the large interiomarginal umbilical primary aperture in the early portion, but differs in having the embracing final chamber obscuring the primary umbilical aperture, the adult possessing only the small sutural secondary openings.
Porticulasphaera, new genus, differs from Globigerapsis, new genus, in having the Globigerinoides-type of secondary apertures on the spiral side in the early coil.
