The central annulus has an irregular shape. Rows of areolae are gently curved and run parallel to the side row of the sectors. Labiate processes are found at the end of these side rows. A small pseudonodulus is located near the mantle. The diameter of these organisms falls within the range of 13-160 µm. In a 10 µm span, there are typically 8-18 areolae, and the distance between the marginal processes measures around 7-9 µm.
