In August 1992 samples of living Hydrobia acuta (Draparnaud, 1805) have been collected in the Baie de Quiberon (Morbihan, France). The identification is elucidated. Giusti & Pezzoli (1984) and Giusti, Manganelli & Schembri (1995) suggested that Hydrobia minoricensis (Paladilhe, 1875) and Hydrobia neglecta Muus, 1963, are junior synomyms of H. acuta. The features of the material from Quiberon support these suggestions: it will be demonstrated that H. minoricensis and H. neglecta fit completely in the conception of H. acuta. H. acuta, well known from the Mediterranean, appears to be also widely distributed in western and northwestern Europe.
