R. South has previously only been recorded from New Zealand, in association with a single host species, Durvillaea antarctica (Chamisso) Hariot (southern bull-kelp). Here we use DNA sequence data from plastid and nuclear markers (chloroplast rbcL, ribosomal LSU, and a nuclear pseudogene copy of COI) to test for the presence of H.&nbsp;durvillaeae beyond the New Zealand region, and on host species other than D.&nbsp;antarctica. Analyses of samples from the Falkland Islands confirm the first record of H.&nbsp;durvillaeae from the Atlantic Ocean. We report that Falkland Islands H.&nbsp;durvillaeae are genetically indistinguishable from samples of this species from New Zealand&#39;s sub-Antarctic Campbell Island, suggesting recent dispersal of the parasite across the Pacific Ocean, presumably by rafting with its buoyant macroalgal host. We also here record H.&nbsp;durvillaeae from New Zealand endemics Durvillaea poha Fraser et&nbsp;al. and D.&nbsp;willana Lindauer.</p>
