Polycirridae from French waters are revised based on material available in French marine stations and newly collected specimens. This work is the third part of the Spaghetti Project aiming to revise French species of "Spaghetti" terebellid worms. It describes eight new species using both morphological (for all species) and molecular (for some species) tools: Amaeana gremarei n. sp., Polycirrus catalanensis n. sp., P. glasbyi n. sp., P. gujanensis n. sp., P. idex n. sp., P. nogueirai n. sp., P. pennarbedae n. sp. and P. readi n. sp., in addition to a previously described species. An identification key for European species of Polycirridae is also provided.
