Traditional morphology-based investigations of the red algal genera Devaleraea and Palmaria (Palmariaceae, Rhodophyta) fail to provide accurate accounts of diversity and distribution for species from the Russian coast of the north-western Pacific. Consequently, there is much disagreement and taxonomic uncertainty regarding several species. To resolve these issues we conducted a molecular-assisted investigation that included a DNA barcode survey (COI-5’) and multilocus (COI-5’, cob, psa A, ITS) phylogenetic analyses. Our analyses indicate that diversity was previously underestimated for the Devaleraea / Palmaria complex. We describe three additional species of Devaleraea: D. sakhalinensis sp. nov., D. kussakinii sp. nov. and D. urupiana sp. nov. We consider D. titlyanoviorum to be an alga with abundant proliferations from the margins, branching to several orders, that is known only from Kunashir Island. Algae from Sakhalin Island and the mainland coast of the Sea of Japan previously identified as D. ...
