This species is a member of the B. launcestonensis group which are of medium size for the genus (2-4.2 mm in length), and rather globular. Their penis is simple. Found in the mid north and north-eastern parts of Tasmania.
This species differs from other members of this group in its central teeth of the radula possessing straighter dorsal edges; female genital system with bend in distal coiled oviduct; mantle cavity with rectum a short S-shape (also in B. wilmotensis, but differs from that species in the coiled oviduct extending to the posterior edge of the bursa copulatrix and the posterior end of the ctenidium overlapping the pericardium).

Original name: Beddomeia inflata Ponder & Clark, 1993. In Ponder, W.F., Clark, G.A., Miller, A.C. & Toluzzi, A. (1993). On a major radiation of freshwater snails in Tasmania and eastern Victoria: a preliminary overview of the Beddomeia group (Mollusca: Gastropoda: Hydrobiidae). Invertebrate Taxonomy 7: 501-750.
Type locality: Heathcote Creek, on Castra Roadd, Upper Castra, Tasmania.
Under large stones and rock slabs in deeper parts of the river. The white egg capsules are laid on the undersides of rocks and are like those of other species of Beddomeia - dome-shaped, with broad attachment base, covered with minute, mainly white sand grains and other fragments and containing a single egg.
