Bottle samples collected during the spring-summer of 1998 in the Sea of Alboran and Barcelona coastal waters contained a total of eleven photosynthetic species: Chroomonas (sensu auctorum) sp., <i>Cryptochloris</i> sp., 3 species of <i>Hemiselmis</i>, 3 species of <i>Plagioselmis</i> including <i>Plagioselmis nordica</i> stat. nov/sp. nov.,<i> Rhinomonas reticulata</i> (Lucas) Novarino, <i>Teleaulax acuta</i> (Butcher) Hill, and <i>Teleaulax amphioxeia</i> (Conrad) Hill. Identification was based largely on cell surface features, as revealed by scanning electron microscopy (SEM). Cells were either dispersed in the water-column or associated with suspended particulate matter (SPM). Plagioselmis prolonga was the most common species both in the water-column and in association with SPM, suggesting that it might be a key primary producer of carbon. Taxonomic keys are given based on SEM. ER -
