Centropyxis decloitri  Stepanek, 1963

Diagnosis: When viewed from above, the shell resembles that of C. aculeata. It differs from it by a cap-shaped lobe that protrudes on the upper side of the shell above the aperture, which ends in an spine without a terminal stone. When viewed from the side it has an irregular shape, lower middle parts above the aperture and a high keel-shaped tail at the back. This protrudes slightly over the edge of the shell with its spine. The color is yellow-light brown. The structure of the shell is irregular and difficult to recognize. The shell is occasionally covered with debris and mineral particles. On the edge of the shell there are 4 spines without terminal stones.

Dimensions: Diameter 70 µm, aperture 24 µm, height 30 µm.
