Diagnosis: The yellowish grey colored test is made of coarser mineral particles, which are connected with a moderate amount of cement. The ventral invagination of the pseudostome is covered with much finer material. The test is conspicuously flat and low arched. The funnel deepens to one half of the depth of the shell or a little more and ends with a smooth rim.
Dimensions: Diameter 85 μm, height at most 40 μm; funnel 23 μm deep and aperture 20 μm in diameter.
