Resumo: The red algal genus Predaea (Rhodophyta, Nemastomataceae, Nemastomatales) currently comprises 20 species found in tropical to temperate waters worldwide. The species going under the name Predaea feldmannii (Nemastomataceae, Nemastomatales) in the Azores is here reduced to subspecies rank as P. feldmannii subsp. azorica on the basis of comparative morphology and rbcL sequence analysis. The evidence presented here includes a phylogenetic tree inferred from chloroplast-encoded rbcL sequences of selected members of the Nemastomatales. P. feldmannii subsp. azorica shares with P. feldmannii subsp. feldmannii linear-oblong outer cortical cells, dichotomously branched cortical fascicles, a large number of auxiliary nutritive cells per cluster, and gonimoblast initiation from the incoming connecting filament near its point of fusion with the auxiliary cell. Differences include a sac-like, lobed thallus and occasional lateral cells on the carpogonial branch in the Azorean subspecies, versus a subcylindrical, subdichotomous habit with marginal lobes, and lack of lateral cells on the carpogonial branch in P. feldmannii subsp. feldmannii. The known distribution of P. feldmannii subsp. feldmannii is worldwide in tropical regions and so far P. feldmannii subsp. azorica is known only from the Azores.

L'espèce connue sous le nom de Predaea feldmannii aux Açores est réduite ici au rang d'une sous-espèce, P. feldmannii subsp. azorica, sur la base de l'analyse morphologique comparative et le séquençage du gène rbcL. Les données présentées ici incluent un arbre phylogénétique des séquences rbcL, qui montre la position évolutive de l'espèce des Açores par rapport à celles d'autres régions. P. feldmannii sous-espèce azorica est caractérisé, comme la sous-espèce P. feldmannii subsp. feldmannii, par des cellules corticales externes linéaires-oblongues, des fascicules corticaux dichotomes, un grand nombre de cellules nutritives auxiliaires, et le développement du gonimoblaste à partir du filament de connexion près du point de fusion avec la cellule auxiliaire. Les différences pour la sous-espèce açoréenne incluent un thalle lobé et en forme de sac, un rameau carpogonial occasionnellement portant des cellules latérales, vis-à-vis d'un thalle subcylindrique et subdichotome avec lobes marginaux ; pour P. feldmannii subsp. feldmannii, l'absence de cellules latérales sur la rameau carpogonial.Association des Amis des Cryptogames (A.D.A.C.)Repositório da Universidade dos AçoresGabriel, DanielaSchils, TomNeto, Ana I.Paramio, LuzFredericq, Suzanne2013-03-18T16:26:14Z2009-07-142011-06-28T15:09:36Z2009-07-14T00:00:00Zinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfhttp://hdl.handle.net/10400.3/1689engGabriel, D.; Schils, T.; Neto, Ana I.; Paramio, L.; Fredericq, S.
