    A new extinct freshwater prosobranch species of the genus Tanousia Servain, 1881, Tanousia stironensis n. sp., of the family Hydrobiidae, is described. It has been discovered in Lower Pleistocene non-marine clayey-sandy deposits of the Stirone River succession (Emilia-Romagna, Northern Italy), well known from a geological and palaeontological point of view. The ecological features of the molluscan assemblages, in which Tanousia stironensis n. sp. widely occurs, suggest that the new species loved slow-current freshwater and warmtemperate climate conditions
