The presence of Gymnura altavela in Italian waters is discussed on the basis of a specimen trawled in the coastal waters of Anzio (central Tyrrhenian Sea). The morphometry of our specimen is compared with data available in the literature and with some museological material of the 19th Century, which represent the only useful source of information for this species in the Italian seas. Never before, relevant data on the morphometry of Italian specimens of this species have been given to scientific literature.
