A description is given of
Physa acuta
Draparnaud, 1805, based on topotypic specimens from the Garonne river basin, and additional samples from the environs of the French cities of Montpellier and Perpignan. It proved indistinguishable, in shell and anatomy, from topotypic
Physa cubensis
Pfeiffer, 1839, thus leading the authors to admit the synonymy of the two nominal species under the older name,
P. acuta.
