Distributional note
According to Gavio & Fredericq (2002), the populations from Rhode Island, New York, Brittany (France) and the south coast of England (Solen area) reported in the literature as "G. doryphora" have been misidentified. They note that evidence from comparative rbcL sequence analysis and morphology suggests that this adventive species in the NE and NW Atlantic and the Mediterranean corresponds with G. turuturu Y.Yamada, originally described from Japan. Introduced accidentally, probably via oysters from Japan, into the Mediterranean (Verlaque et al. 2015: 179) being first found in the Etang de Thau (France) in 1982 (Rioull, Guiry & Codomier 1985). Cormaci, Furnari & Alongi (2021: 72) note "This species was introduced into the Mediterranean Sea by mollusc culture (Cormaci et al., 2004: 165). It was recorded not only in sites in which mollusc farming is carried out [as the Étange de Thau (France) (Verlaque et al., 2005: 487), Venice Lagoon (Italy) and Mar Piccolo of Taranto (Italy) (Cecere et al., 2011: 29)], but also in other sites like the Port of Ancona (Italy) (Falace et al., 2010), Mediterranean Israeli coast (Hoffman, 2014: 677, figs 3-4), and an artificial reef near Marina di San Vito Chietino (Italy) (Olivieri in Ravera et al., 2016: 44). In the above sites in which mollusc farming is not practised, we can suppose that the species was introduced by shipping. In particular, it could be also possible that the species reached the site of Abruzzo (Marina di San Vito Chietino), located near the Port of Ancona, via natural way. Finally, it should be noted that the species was often misidentified with G. doryphora (see also the note to the genus Grateloupia at the entry 'G. doryphora'). It should be noted that recently Petrocelli et al. (2020) state that this alien species is neither inva-sive, at least in the Mar Piccolo of Taranto (Italy), nor a menace to Mediterranean biodiversity, but, conversely, a resource of bioactive substances." - (19 August 2009) - G.M.
