The purpose of this application, under Article 23.9.3 of the Code, is to conserve the names Eatoniella Dall, 1876 and EATONIELLIDAE Ponder, 1965, which are junior subjective synonyms of Paludestrina d’Orbigny, 1840 and PALUDESTRINIDAE Newton, 1891, respectively. To date, Paludestrina d’Orbigny, 1840 and PALUDESTRINIDAE Newton, 1891 have been regarded as junior objective synonyms of Hydrobia Hartmann, 1821 and HYDROBIIDAE Troschel, 1857 based on the designation of Cyclostoma acutum Draparnaud, 1805 as type species of Paludestrina by Bourguignat, 1887. However, the earlier and overlooked type species designation of Paludina nigra d’Orbigny, 1840 by Nevill (1885) as the type species of Paludestrina renders Paludestrina a subjective synonym of Eatoniella. The names Paludestrina and PALUDESTRINIDAE have never been used in the sense of Eatoniella and EATONIELLIDAE, but have been frequently used mistakenly in the sense of Hydrobia and HYDROBIIDAE. To avoid confusion, the suppression of Paludestrina and PALUDESTRINIDAE is proposed. Paludina nigra d’Orbigny, 1840 is a junior homonym of Paludina nigra Quoy & Gaimard, 1835 and its junior subjective synonym Eatoniella latina Marincovich, 1973 is proposed as a replacement name.
