Lodderena minima, common name the minute liotia, is a species of small sea snail, a marine gastropod mollusk in the family Skeneidae.
The size of this minute shell varies between 0.5 mm and 1.1 mm. The translucent white shell has a planorbiform shape with a flat or slightly raised spire. The shell contains about three whorls with 1ý whorl in the protoconch. The shell is devoid of ornament, except the regular spiral groove. It has, however, a remarkably thickened, smooth varix round the circular aperture, and a granularly margined, wide umbilicus.
This marine species is endemic to Australia and occurs off Queensland, southwards to Tasmania and South Australia.
