Reticulofenestra rotaria Theodoridis, 1984


Medium size [5.0 - 8.0µm] circular species of Reiculofenestra Hay, Mohler & Wade (1966) having a wide central area whose diameter is about twice greater than the width of the pelaga.


Reticulofenestra rotaria can easily be distinguished from Reiculofenestra zancleana di Stefano & Sturiale (2010) by its narrower pelaga and wider central area.
