Abstract
We report an introduction of the predatory land snail Poiretia delesserti (Bourguignat, 1852) (Spiraxidae) from Albania and Greece in Cagnes-sur-Mer in southeastern France discovered by a citizen scientist. An uncontrolled expansion of this species in this region, which is characterized by a high number of endemic land snail species, is likely to result in extinctions. Therefore, we recommend the nature conservation authorities to survey the site to quantify population density and extent and to eradicate the introduced population of P. delesserti via manual collection.
