On some preoccupied gastropod names introduced by Petar S. Pavlović (Hydrobiidae: Planorbidae)

In this work, we provide replacement names for three fossil gastropod taxa described by Petar S. Pavlović, which are all currently junior primary homonyms. The newly introduced names include Gyraulus lacertula Gojšina et Vujić, nom. nov. (replacement name for Planorbis fragilis Pavlović, 1903, non Dunker, 1850), Gyraulus explanorbis Gojšina et Vujić, nom. nov. (replacement name for Planorbis verticilloides Pavlović, 1931, non Serres, 1851) and Micromelania megalomania Gojšina et Vujić, nom. nov. (replacement name for Micromelania subulata Pavlović, 1927, non Westerlund, 1902).
