The bait worm Marphysa victori Lavesque, Daffe, Bonifácio & Hutchings, 2017
was originally described from Arcachon Bay, France. In the original description,
the authors suggested that it may have been introduced, although definitive
evidence was lacking at the time. In this paper, we confirm that M. victori is an
exotic species originating from East Asia, probably a native of China or Japan. This
species was most likely introduced into Arcachon Bay in the 1970s with non-native
oysters Crassostrea gigas Thunberg, 1793. The Asiatic origin of this species is
confirmed based on both morphological and molecular evidence. Comparison of
the type specimens of M. victori with those of Marphysa bulla Liu, Hutchings &
Kupriyanova, 2018 described from the Yellow Sea, China, showed no morphological
or molecular differences and therefore the more recently named M. bulla is
relegated to a junior synonym. This is the first example of a large-sized errant
invertebrate species being introduced with oysters into Arcachon Bay.Read less <
