Original Description
Extra details from original publication
Occurrence: The subspecies ranges from the topmost part of Globigerinatella insueta zone in the Brasso formation, into the overlying Globorotalia fohsi barisanensis subzone in the Cipero and Brasso formations of Trinidad. It probably does not extend into the topmost part of the latter subzone. In Venezuela, it occurs in the middle part of the Siphogenerina transversa zone in the Pozon formation, and it has also been observed in the Bissex Hill formation of Barbados.
