A new species of polyclad flatworm, Idiostylochus tortuosus
gen. nov., sp. nov. (Polycladida, Idioplanidae), from Arcachon Bay
(France) is described. This description is based on morphological
analysis and a molecular analysis using partial sequences of the 28S
and Cytochrome Oxidase I (COI) genes. After the molecular analysis Idiostylochus
gen. nov. appears as the second genus of the Family Idioplanidae, and
closely related to the family Latocestidae and the genera Leptostylochus and Mirostylochus.
The molecular data revealed the new species may belong to an Indonesian
or Indo-Pacific family, closely related to genera with origin in South
Pacific Ocean waters. This species was found feeding on the oysters and
mussels of the Arcachon farms.
Key words: Acotylea, Idioplanidae, non-native species, Magallana gigas, oyster culture.
