Species of the B. hullii group are found in the northern half of Tasmania. Their shells are small (1.7-3.7 mm in length; most less than 3.5 mm), simple, ovate-conic to broadly conic, with a thin inner lip and no columellar bulge. The periphery of the last whorl of the shell is rounded, subangled or angled and the penis simple.
B. turnerae differs from other Beddomeia species from north central Tasmania (excluding B. lodderae) in shell having a small umbilicus.

Original name: Beddomeia turnerae Ponder & Clark, 1993. In Ponder, W. F., Clark, G. A., Miller, A. & 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: Small tributary of Minnow River, 3 km E of Kenzies Hill, Tasmania (41°29'06" S, 146°23'06"E).
Under stones and amongst gravel and on mud,also on leaves of ferns hanging in water on edges of streams and seeps. 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.
Small tributary and seeps of Minnow River, 3 km east of Kenzies Hill, Tasmania.
All species of Beddomeia are geographically isolated and have restricted ranges.
This species is on the Tasmanian Threatened Species Protection Act 1995 as Rare (small population at risk).
