Original Description
Test either Hantkenina-like or distinctly Globigerina- like, almost planispiral to trochoidal. Chambers of Hantkenina type with axially situated spines, those of Globigerina type rounded peripherally, truncate toward umbilicus. Sutures straight to slightly curved in direction of coiling. Apertures large, arcuate, directed toward umbilicus, occasionally with liplike projections. Umbilicus subcircular, as a rule large, deep, with covering plate. Surface ornamented by rugosities of various size and type, either distributed irregularly or arranged in rows radiating from a central point on the surface toward the aperture (meridional pattern).

Extra details from original publication
Remarks: The Upper Cretaceous genus Rugoglobigerina contains the hantkeninoid subgenus Plummerella and the Globigerina-like subgenus Rugoglobigerina, both of which carry the characteristic rugose surface, which in typical forms displays a peculiar meridional pattern, A further indication of relationship of these two subgenera is the occurrence of spines in the early stages and truncate Globigerina chambers in the late ontogenetic stages of some species. The covering plate across the umbilicus was not found in PlummereJla, but from the general morphology of the tests its presence has to be expected in v.-ell-preserved specimens. The genus Rugoglobigerina differs from all other Cretaceous and Tertiary Globigerinas by the strongly rugose, as a rule regularly ornamented surface, by a covering plate across the umbilicus, and by the development of hantkeninoid chambers and of truncate Globigerina chambers, with large arcuate apertures directed toward the umbilicus.

Occurrence: Upper Cretaceous, Trinidad, B. W. I., Eastern Venezuela, Texas, U. S. A., and Egypt.
