Remarks The Adriatic material studied in the present work fully matches the redescription of S. halimedae made by López de la Cuadra and García-Gómez (2001) who clearly separated it from the very similar species S. discoidea (Busk, 1859). Lepralia discoidea was originally described from Madeira, but it is thought that other records from the European continental shelf may correspond to at least one new undescribed species. López de la Cuadra and García-Gómez (2001) also stated that many previous records of S. discoidea in the Mediterranean are probably referable to S. halimedae, a species restricted to the inner Mediterranean. However, S. discoidea s. l. seems to be also present at least in the western Mediterranean, as well as in the Atlantic, so its presence in the Adriatic is not impossible.
