An updated checklist and biogeography of the Sardinian large branchiopods, with a focus on Spinicaudata (Crustacea, Branchiopoda)


The large branchiopod fauna of Sardinia is reviewed based both on literature and newly collected data. Based on the available evidence, 13 taxa are present on the island (8 Anostraca, 2 Notostraca, and 3 Spinicaudata). Among them, the finding of the spinicaudatan Leptestheria dahalacensis is new for Sardinia, while the spinicaudatans Cyzicus bucheti and Eulimnadia sp. were overlooked in the most recent synopses on the fauna of the island due to misidentifications. Conversely, Cyzicus tetracerus and Limnadia lenticularis, previously erroneously reported based on misidentifications, must be excluded from the fauna of Sardinia. The finding of Eulimnadia sp. is the first record in Europe and the northernmost record of the genus. The occurrence of Leptestheria dahalacensis in Sardinia is rather unexpected and probably due to its accidental introduction linked with rice cultures. At least four of the 13 Sardinian large branchiopod species are absent from the Italian mainland and Sicily, stressing the uniqueness of its fauna and its significant contribution to the Mediterranean inland water crustacean diversity.
