ABSTRACT This study is the first to report the presence of the polychaete Parasphaerosyllis indicaMonro, 1937 (Syllidae) near the coastal areas of Easter Island (27°10'S, 109°20'W). This species has a circumtropical geographic distribution and low abundance and frequency rates in relation to other Syllidae species (12) collected from Easter Island. With P. indica, the benthic polychaetes biodiversity of Easter Island is now 71 species.
