A compilation of our present knowledge of the water mites (Acari: Hydrachnidia) adapted to life in standing waters on thethree large islands in the western Mediterranean (Corsica, Sardinia and Sicily) is provided. In addition to published data,this study deals with a rich volume of new material from recent field work, mostly deriving from intermittent ponds andpools, an extremely poorly investigated yet peculiar habitat type in the Mediterranean area. Species richness of water mitesreported for the standing waters of the three islands amounts to 91 species. Out of the 47 species for which we present newdistributional data, Hydrachna incisa Halbert, 1903, Hydrachna leegei Koenike, 1895, Piersigia limophila Protz, 1896,Hydryphantes crassipalpis Koenike, 1914 and Piona laminata (Thor, 1900) have not been recorded previously from theMediterranean area. Most of these species were believed to have typical North European distributions. In addition to these,a further 13 species are recorded for the first time from the area covered. In total, 11 species are new for Italy, seven more arenew for Sicily, three for Sardinia and seven for Corsica. Redescriptions are given of Axonopsis complanata (Müller, 1776)(A. graeca, nov. syn), Brachypoda baderi (reported for the first time after the original description from Abruzzo, Italy,synonymization with B. mutila rejected) and B. mutila (recorded for the first time outside Algeria with certainty). For eachspecies, information is given on habitat preference and geographical distribution; the significance of the data is discussedunder perspectives of zoogeography and nature protection. The completeness of our knowledge for the three investigatedisland is assessed using rarefaction curves and non-parametric estimators of species richness; while Sicily can be consideredfairly well known, Corsica and Sardinia require further sampling to assess their water mite diversity.
