The Lichadonisia island group is located between Maliakos and the North Evian Gulf, in central Greece. Lichadonisia is one of the few volcanic island groups of Greece, consisting mainly of lava flows. Today the islands are uninhabited with high numbers of visitors, but permanent population existed for many decades in the past. Herein, we present for the first time the land snail fauna of the islets and we compare their species richness with islands of similar size across the Aegean Sea. This group of small islands, provides a typical example on how human activities in the current geological era, i.e., the Anthropocene, alter the natural communities and differentiate biogeographical patterns.
