RESUMO. O género Dictyota Lamouroux (Dictyotaceae-Phaoephyta) no litoral do Estado da Bahia, Brasil. Este estudo faz parte de um levantamento florístico de algas marinhas bentónicas do estado da Bahia, desenvolvida pela Universidade Federal da Bahia. Através da análise de caracteres morí- o-anatómicos foram reconhecidos e ilustrados nove tdxons: D. bartayresiana J. V. Lamouroux, D. cervicornis Kützing f. cervicornis, D. cervicornis f. pseudohamata (Cribb) De Clerck & Coppejans, D. ciliolata Sonder ex Kiitzing, D. crispata J. V. Lamouroux, I). jamaicensis W. R. Taylor. D. menstrualis (Hoyt) Schnetter, Hornig & Weber-Peukert, D. mertensii (Martius) Kiitzing e D. pulchella HOrnig & Schnetter. Referéncia da descritjdo original, basiónimo, descri0o morfológica, distribuiÇao geográfica ao longo do litoral brasileiro, incluindo mapa e comcntários taxonómicos foram apresentados para cada táxon estudado. Chaves dicotómicas para identificaÇáo das especies, bem como tabela comparativa dos táxons é apresentada. D. crispata constitui-se em primeira referEncia para o Brasil.

ABSTRACT. The genus Dictyota (Dictyotaceae-Phaeophyta) on the littoral of the State of Bahia, Brazil. This study is part of a taxonomic survey of the benthic marine algae, carried out by Universidade Federal da Bahia. Based on detailed morphological and anatomical analyses were recognized and illustrate nine taxa: D. bartayresiana J. V. Lamouroux, D. cervicornis Ktitzing f. cervicornis, I). cervicornis f. pseudohamata (Cribb) De Clerck & Coppejans. D. ciliolata Sander ex Kiitzing, D. crispata J. V. Lamouroux, D. jamaicensis W. R. Taylor, D. menstrualis (Hoyt) Schnetter, Hornig & Weber-Pcukert, D. mertensii (Martius) Kiitzing e D. pulchella Hornig & Schnetter. Reference to the original description, basionym, morphological description, geographical distribution along the Brazilian littoral, including map and taxonomical comments was presented for each taxon studied. Dichotomic keys for identification for the species, and comparative table for taxons is also presented. I). crispata is recorded in the fi rst time for the Brazil.
Key words. Phacophyta, taxonomy, Dictyota, Bahia, Brazil.
