Giangrande and Licciano (2008) re-examined several specimens previously identified as Megalomma vesiculosum from the Adriatic and Tyrrhenian Sea and Mediterranean Spain and found all of them to belong to Megalomma lanigera (Grube, 1846) (now Acromegalomma lanigerum , see Gil and Nishi 2017 ). They conclude that Megalomma vesiculosum is absent from the Mediterranean and that all Mediterranean material of Megalomma vesiculosum should be assigned to Megalomma lanigera .
