SUMMARY:

The Sabellidae family currently has 40 genera with more than 400 described species, being one of the most diverse groups of sedentary annelids, easily recognized by the presence of a showy radiolar crown in most species. The identification of species in the family focuses on characteristics of the three regions of the body: crown, thorax and abdomen. Until 2012, approximately, 21 genera and 40 species were recorded for the Brazilian coast, but, after constant synonymization, only 11 of the Sabellidae species recorded for Brazil are currently recognized, of which ten were originally described in Brazilian territory. The objective of the present study was to carry out a systematic-morphological survey of the family on the southern coast of Rio de Janeiro to truly understand the diversity and status of each of the species found. Collections were carried out on different substrates, the specimens were anesthetized, fixed with 4% formalin and kept in 70% ethanol. As a result, 16 species belonging to five genera were reported, five being new occurrences for the Brazilian coast. Furthermore, new species of the genera Acromegalomma, Notaulax and Pseudopotamilla added to the family's diversity on the Brazilian coast. However, many taxonomic confusions still need to be evaluated and new morphological characters need to be identified to improve the process of identifying the family's
genera and species.
