Hessle (1917) created genus Neoamphitrite and placed Terebella figulus Dalyell, 1853 in it, with Amphitrite johnstoni Malmgren, 1867 as junior synonym of T. figulus. As far as I can tell from a quick look, this is still thought to be the case (eg Holthe, 1986, Mar Inverts Scandinavia #7, also the Hartmann-Schroeder book 2nd ed), although Fauvel (1927) has A. johnstoni as valid, and the distinctness of Hessle's Neoamphitrite from Amphitrite has been challenged. So most likely the valid species entry for A. johnstoni in WoRMS is a dubious status, and the name should not be in use. Perhaps one of the WoRMS Terebellidae editors could look at this and comment?
Just be a bit careful with relying on distributions as reported in WoRMS. They often come from external people's regional lists (click on the '[details]' link to see which) and are not verified by the taxonomic editors. It is difficult to challenge items in such lists without a lot of work.
