Liotella corona

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

Description
The height of the white shell attains 0.28 mm, its diameter 0.82 mm. The minute shell has a discoid shape. It is not nacreous. The spire is sunken. The umbilicus is wide and shallow. The shell consists of three whorls. The last half-whorl comes scarcely in contact with the others, and is suddenly and deeply deflected.

Sculpture: The body whorl is ringed by 16 thick, projecting, distant ribs which fade above and below at the sutures. These ribs continue on the suture for about half a whorl. The interstices of the ribs are faintly spirally scratched. The very oblique aperture is circular and fortified by a varix.

Distribution
This marine species is endemic to Australia.
