Extra details from original publication
Globotruncana undulata est voisine de Globotruncana falsostuarti Sigal. Les dimensions, le nombre des loges du dernier tour et le nombre de tours de la spire de ces deux espèces sont semblables. Du côté latéral leur aspect est différent. Globotruncana falsostuarti est dissymétrique et montre une double carène; par contre l'espèce de Tarfaya est presque symétrique et unicarénée.
