The new checklist of the Italian Fauna: Rotifera

We present a data set reporting the checklist of the species of the phylum Rotifera for Italy, updating theone previously published in the series ‘Checklist delle Specie della Fauna d'Italia’ in 1995. The recordsof the updated checklist refer to the 483 taxa at the species and subspecies level currently known fromnational Italian territories (119 Bdelloidea, 362 Monogononta, 2 Seisonacea) at the regional level (22terrestrial and nine marine geographical units). The records refer to various freshwater, limno-terrestrial,and marine coastal habitats. The previous checklist reported 245 taxa (54 Bdelloidea, 189 Monogononta,2 Seisonacea): three taxa were removed because currently considered not valid and 241 were added,scanning 21 papers we found that were published between 1993 and 2020, expanding the regional recordsand including four papers older than 1993 with overlooked records in the previous checklist. The Rotiferadata are part of the updated Checklist of the Italian Fauna, which is viewable on the LifeWatch Italyplatform at https://www.lifewatchitaly.eu/en/initiatives/checklist-fauna-italia-en/checklist and is freelyavailable on the LifeWatch Italy Data Portal (https://dataportal.lifewatchitaly.eu/data). The checklist willbe dynamically updated with new records; this paper describes the state of the art of the data set regardingRotifera on May 2021.
