","OrigTitleTranslFlag":0,"Authorstringtrunc":"De Clerck, O. <i>et al.</i>","Englishabstract":"<i>Dictyota</i> is a genus of tropical to warm temperate brown algae characterized by parenchymatous, flattened thalli that grow from a single, transversely oriented apical cell. <i>Dictyota</i> is currently distinguished from allied genera of the tribe Dictyoteae (<i>Dilophus</i>, <i>Glossophora</i>, <i>Glossophorella</i>, and <i>Pachydictyon</i>) by the structure of the cortical and medullary layers, as well as the relative abundance of surface proliferations. Even though the traditional classification of the Dictyoteae has repeatedly been criticized in the past, the absence of sound molecular data has so far discouraged any new taxonomic proposals apart from a merger of <i>Dilophus</i> with <i>Dictyota</i>, which has been accepted by only part of the phycological community. Phylogenetic analysis of <i>rbc</i>L gene, partial 26S rDNA sequence, and combined data sets, including four of five generitypes, demonstrates that the traditional classification does not accurately reflect the evolutionary history of the group. None of the genera are resolved as a monophyletic clade. Hence, a merger of <i>Glossophora</i>, <i>Glossophorella</i>, and <i>Pachydictyon</i> in <i>Dictyota</i> is proposed. Two new genera, <i>Canistrocarpus</i> (incorporating <i>D. cervicornis</i>, <i>D. crispata</i>, and <i>D. magneana</i>) and <i>Rugulopteryx</i> (accommodating <i>D. radicans</i>, <i>Dil. suhrii</i>, and <i>Dil. marginata</i>), are proposed. Both genera are supported by molecular indications and a combination of reproductive and vegetative characters. The position of <i>Dil. fastigiatus</i> as a clade sister to <i>Dictyota</i> s.l. and the absence of <i>Dil. gunnianus</i>, the generitype of <i>Dilophus</i>, from the analyses, prevented us from making a more definite statement on the status of the latter genus.
