Guía y claves para el reconocimiento de las subfamilias, géneros y especies de Syllidae registradas a lo largo de la costa de Chile, archipiélago Juan Fernández e isla de Pascua (Annelida: Phyllodocida: Syllidae)

An updated review of polychaete species of the family Syllidae registered so far in the southeastern Pacific Ocean along the coast of Chile, from the locality of Arica (18o28’ S) in the northern border to Cape Horn (55o56’ S) at the southern end, in Juan Fernández Archipelago (33°40’ S, 79°00’ W) and Easter Island (27°09’ S, 109°23’ W) is presented. Keys to the determination of the subfamilies, genera and species of syllids registered in Chile are provided. A chronological list of the authors who have reviewed specimens for each 8 G. SAN MARTÍN et al. of the species considered valid is included. All collecting localities of each species in chronological and latitudinal order, with the author’s name and the date of the publication in which the locations were identified are included. Information on morphology, biology, ecology and systematics of syllids in general is provided. The number of syllids registered so far along the Chilean coast is 63 species, of these 56 species have been recorded to the continental coastal littoral of Chile, five species in Juan Fernández Archipelago and eight species in Easter Island, in 25 genera, distributed in five subfamilies, in the three areas considered within the limits of the Chilean sea. Of the 63 species of syllids recorded so far along the coast of Chile, including the austral channels and fjords, the Juan Fernández Archipelago and Easter Island, 32 record the coast of Chile as type locality, two the Juan Fernández Archipelago, and of them 22 species are considered endemic to Chile.
