RESUMO

The present Dissertation is the result of a taxonomic survey on the species of polychaetes belonging to the families Terebellidae and Trichobranchidae collected by the projects "Biodiversity of Polychaetes on Rocky Shores along the coast off the State of São Paulo, Brazil", "Benthic Marine Biodiversity on the State of São Paulo", and "REVIZEE/South Score/Benthos", ranging from the intertidal zone to deep sea environments, with the goal of enlarging the taxonomic knowledge of these families on the Southeastern and Southern coast of Brazil. Identifications were based on morphological characters, specimens were observed under stereo- and optic microscopes and, in some cases, scanning electron microscope, with the help of specialized literature. Identification keys and detailed descriptions, with illustrative tables, were elaborated for each species. In the present work, 8386 specimens were identified, belonging to 15 genera and 21 species, of which 14 genera and 18 species belonging to the family Terebellidae, subfamilies Terebellinae, Thelepodinae and Polycirrinae, and 1 genus and 3 species belonging to the family Trichobranchidae. Of those, 6 species of terebellids were new to science: Amaeana sp., Phisidia rubra Nogueira &Alves, 2006, Polycirrus sp., Pseudostreblosoma brevitentaculatum Nogueira &Alves, 2006, Terebella sp. 1 and Terebella sp. 2. The genus Phisidia Saint-Joseph, 1894 is new occurrence to Brazilian coast. Thus, the present Dissertation can be used as an identification guide to help researchers, not only specialists, in the identification of part of the species of Terebellidae and Trichobranchidae occurring on the Southeastern-Southern regions of Brazil. It is also supposed to help researchers with the identification of species from localities outside the geographic range of the three projects here investigated, as well as further ecological and biogeographic studies, enlarging the knowledge of the biodiversity of Terebellidae and Trichobranchidae occurring in Brazil and worldwide.
