Bithynia hambergerae was described by Reischütz et al. (2008) from River Plavnica, the northern tributary of Skadar Lake. In the original description, Reischütz et al. (2008) mentioned similarity of this species with the two other Bithynia species known from the Skadar Lake basin, i.e., Bithynia radomani Glöer & Pešić, 2007 and Bithynia montenegrina Wohlberedt, 1901. From the two abovementioned species, Bithynia hambergerae differs in the larger dimensions of the shell (12.3–13.8 mm vs. 9.7–11.3 (mean 10.5) mm in Bithynia radomani, 10.8–12.6 (mean 11.7) in Bithynia montenegrina) and the morphology of penis (moderately slender penis and perennial appendix and the relatively longer flagelum - see Fig. 3f).
