Beddomeia protuberata is a species of endemic freshwater snail in the family Tateidae, found in northern Tasmania, Australia. The shells look ovate and periostracum yellow with some pustules, length between 2.29 mm and 2.93 mm and width between 2.01 mm and 2.34 mm. Beddomeia protuberata has 1.75 protoconch whorls. Its image of microsculpture is uniform and its wrinkles arranged weakly and helically. The teleoconch of beddomeia protuberata has 2.2 to 2.7 convex whorls, and the ratio of convexity is 0.15 to 0.24. Sculptures of the teleoconch are vague with prosocline growth lines. The margin of the last whorl is evenly circular. The thickness and width of inner lips are medium sizes, and the columellar swelled up prominently. The outer lips of Beddomeia protuberata is prosocline, which means the shell leans forwards compared to the shell’s coiling axis. The width of their umbilicus is between 0.31 mm to 0.51 mm. The umbilicus of female beddomeia protuberata are wider than the umbilicus of male.
Distribution
The beddomeia protuberata group is found only Tasmania, and is limited by many factors, both intrinsic and extrinsic. For example, the local geology and local hydrological conditions (rainfall and water chemistry etc.) The products of human activities also influence and limit the distribution of Beddomeia protuberata. As a result, beddomeia protuberata is a very rare and endemic species in Australia, listed as rare status in the Threatened Species Protection Act (1995).
