Extra details from original publication
Remarks: This subspecies differs from Glt. ventricosa ventricosa in the less globular, somewhat conical chambers on the umbilical side, each bearing a more or less well developed keel at its top, around the umbilicus. It differs from Glt. gagnebini Tilev in the same characteristics and in the concavity of the spiral side in Glt. ventricosa carinata.

Approximate range: Upper Santonian. Associated with Glt. lapparenti coronata Bolli, Glt. lapparenti angusticarinata Gandolfi, Glt. fornicata Plummer, and Glt. lapparenti lapparenti Brotzen. Frequent. The type is from Le Kef-Mellegue, northwestern Tunisia.
