ABSTRACT
Paralacydoniid polychaetes belonging to the genus Paralacydonia Fauvel 1913 were collected during the REVIZEE Program/South Score/Benthos ("Avaliação do Potencial Sustentável dos Recursos Vivos na Zona Econômica Exclusiva") on the outer shelf and continental slope off the south-southeastern coast of Brazil between 156 and 400 m depth. This new report extends the known geographic distribution of the family, which had previously been recorded in the North Atlantic as far as the Gulf of Mexico. Paralacydonia is here treated as monotypic; P. mortenseni Augener 1924 and P. weberi Horst 1923 are considered synonyms of Paralacydonia paradoxa Fauvel 1913.
RESUMO
Poliquetas paralacidoniídeos pertencentes ao gênero monotípico Paralacydonia Fauvel 1913 foram coletados durante o Programa REVIZEE/Score Sul/Bentos ("Avaliação do Potencial Sustentável dos Recursos Vivos na Zona Econômica Exclusiva") na plataforma externa e talude continental na costa sul-sudeste do Brasil entre 156 e 400 m de profundidade. Esta nova ocorrência amplia grandemente a distribuição geográfica dos representantes da família, a qual tinha sido previamente registrada no Atlântico Norte até o Golfo do México. Paralacydonia é tratado aqui como monotípico; P. mortenseni Augener 1924 e P. weberi Horst 1923 são considerados sinônimos de Paralacydonia paradoxa Fauvel 1913.
