Species in the B. paludinella group have rather large shells for the genus (2.8-5.6 mm in length), with depressed spire and broad, thickened inner lip. Penis simple. Found in the western part of the middle north coast of Tasmania.
This subspecies can be differentiated from B. paludinella paludinella by the U-shaped part of the coiled oviduct being orientated obliquely as opposed to horizontal, the capsule gland being shorter than the albumen gland, in having 4-6 hypobranchial gland ridges (not 6-9), more numerous cusps on the central and marginal radular teeth and no trace of axial elements on the protoconch.

Original name: Beddomeia paludinella levenensis 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: Leven River, at Clarkes Bridge, Tasmania.
This species lives in strongly flowing water where it shelters beneath large, stable rocks. Egg capsules presumably 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. Development direct.
This taxon is known from the Leven River, Tasmania.
All species of Beddomeia are geographically isolated and have restricted ranges.
