Shell pupiform, with strongly convex whorls; operculum with 2-3 long pegs. Similar to Fluvidona anodonta and F. petterdi [1] [2][1] [2] in shell features but in opercular characters these species differ in having shorter opercular pegs. The two taxa also differ in several anatomical characters but both have a simple penis.
This is one of several species of Fluvidona found in northern New South Wales and southern Queensland. They are all very similar, being separated on small differences in size and shape of the shells and in anatomical details. They have elongate-conic shells with adults having a slightly thickened aperture and the operculum bears one or more pegs.

Type locality: Burleigh Heads, Queensland.

Most species of Fluvidona are geographically isolated and have restricted ranges. This species is unique amongst Australian described mainland tateids in being able to aestivate and withstand drying.
