Cyclostrema eumorpha Suter, 1908 Lodderia eumorpha is a species of small sea snail or micromollusc, a marine gastropod mollusc in the family Skeneidae.

The very small, umbilicate shell has a turbinate shape.

The sculpture consists of 5 prominent spiral riblets, the first just above the periphery.

They are convex, the last flattened between the suture and the first spiral riblet.

The peristome is continuous, smooth inside and ornamented outside by the spiral sculpture.
