Test free, trochospiral, chambers spherical to ovate, sutures depressed, wall calcareous perforate; surface pitted, cancellated or finely hispid, primary aperture umbilical in position as in Globigerina d'Orbigny; with one or more secondary sutural apertures on spiral side as in Globigerinoides Cushman. In the adult stage, the primary aperture and umbilicus is covered by umbilical bullae with commonly two or three accessory infralaminal apertures at the margins of the bulla. The secondary sutural apertures on the dorsal side are not covered by sutural bullae.

Extra details from original publication
Remarks: Globigerinanus, new genus is a non-umbilicate form belonging to the group of the bullate Globigerinidae whose umbilical area is covered by a perforate, inflated, plate-like final structure (bulla), or large enveloping final chamber, with a number of accessory infralaininal or sutural apertures at the base of the final element and which may or may not covered by secondary sutural bullae. It is closely related to genus Globigerinoides Cushman from which it has been evolved at the late most Burdigalian by the secretion of a swollen, finely perforate umbilical bulla covering the umbilicus and primary aperture, with no apparent relation to the coiling mode of the test.
