Species included in the B. bellii group are small to medium-sized (2.3-3.0 mm in length), ovate-conic to ovate and usually have a columellar swelling. The penis is simple (as in B. bellii and B. protuberata) or with a lenticular brown gland in the middle. Species in this group are restricted to north-western Tasmania.
This species differs from the otherwise similar Beddomeia mesibovi, B. topsiae, B. salmonis, and B. gibba, in the shell lacking a columellar swelling.
