Liotella annulata is a species of minute sea snail, a marine gastropod mollusc in the family Skeneidae.


The diameter of the shell is 1.5 mm. The opaque white shell has a planorbiform shape. It is flattened above, rounded below, with somewhat distant longitudinal lamellae, above and below. Otherwise it is smooth. The umbilicus is wide. One of the ring-like lamellae forms the peristome.


This marine species is endemic to Australia and occurs off South Australia and Tasmania.
