Species of the B. hulli 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.
This species differs from other members of this group in its shell with a smooth protoconch; mantle cavity with short S-shaped rectum; female genital system having obliquely oval bursa copulatrix with antero-ventral duct, coiled oviduct not embedded in connective tissue, seminal receptacle antero-ventral and capsule gland about equal in length to albumen gland (shorter in other taxa).

Original name: Beddomeia wiseae 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: Blizzards Creek, on Youngs Road, south of Irishtown, in seeping gully, Tasmania.
Not much is known of the biology and ecology of this species. 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.
Known from Blizzards Creek, Tasmania.
All species of Beddomeia are geographically isolated and have restricted ranges.
This species is on the Tasmanian Threatened Species Protection Act 1995 as Vulnerable.
