RESUMO:

Rocky shores are ecosystems of great species richness, abundance and endemism of benthic
organisms; polychaeta is one of the most abundant and diverse, occurring in microhabitats
and forming associations with other organisms as algal tufts and mussel banks. The present
study is the first work with high taxonomic resolution of polychaeta associated with the rocky
shores in Sepetiba Bay, including different microhabitats and a large sample. The aim of that
study is comparing the species richness, composition and abundance of polychaetes
associated with algal tufts and mussel banks in five places in Sepetiba Bay, as well as, to
identify and inventory polychaetes associated with rocky shores. Algal tufts, in general,
exhibit higher species richness than mussel banks; however, mussel banks had higher
similarity than algal tufts. No exclusive species were detected for each environments.
Including all sampling points, algal tufts from Praia do Sino presented the highest species
richness. In total 62 species were sampling, the most abundant were Naineris aurantiaca,
Timarete caribous and Pseudonereis sp. Among the species found four are new records for
the Brazilian coast, one new record for the southeast region and 33 are new records for the
Sepetiba Bay, besides another important result to the redescription of N. aurantiaca. The
present work to increase the knowledge about the polychaetes species in associations with
rocky shores and allowed to detect some species that involve complicated taxonomic
questions and are potential new species for the science.
