Reticulofenestra zancleana
Reticulofenestra zancleana di Stefano & Sturiale, 2010
Circular species of Reiculofenestra Hay, Mohler & Wade (1966) having a large central area without a permanent central structure. The shape of the central opening is quadrilateral in polarised light.
Reticulofenestra zancleana can easily be distinguished from Reiculofenestra rotaria Theodoridis (1984) by its wider pelaga and narrower central area.
