Resumen

CAPA, María; SAN MARTIN, Guillermo  y  LOPEZ, Eduardo. Autolytinae, Eusyllinae y Exogoninae (Syllidae:  Polychaeta) del Parque Nacional de Coiba, Panamá. Rev. biol. trop [online]. 2001, vol.49, n.2, pp. 621-628. ISSN 0034-7744.

This is the second paper on the Syllidae (Polychaeta) from hard substrata of the Coiba National Park (Pacific coast of Panama) (the first paper treated Syllinae). On this second paper nineteen species belonging to eleven genera of the subfamilies Autolytinae, Eusyllinae and Exogoninae (Syllidae:  Polychaeta) are reported. The samples were collected by SCUBA diving, either by removing 4 kg blocks of dead coral (Pocillopora spp.) or scraping off 25 x 25 cm quadrats of Telesto multiflora or algae (Dyctiota cf. flavellata, Padina cf. durvillaei and another currently unidentified species). They were collected during four expeditions carried out between 1996 and 1998. Four species are newly reported for the Eastern Pacific:  Eusyllis lamelligera Marion & Bobretzky, 1875, Exogone exmouthensis Hartmann-Schröder, 1980, Proceraea cf. cornuta (Agassiz, 1863) and Sphaerosyllis (S.) magnidentata Perkins, 1981. Ten species are reported for the first time from the Central America Pacific coast:  Amblyosyllis cf. granosa Ehlers, 1897 (sensu Westheide 1974), Amblyosyllis speciosa Izuka, 1912,  Autolytus multidenticulatus Westheide, 1974, Exogone naidinoides Westheide, 1974, Grubeosyllis concinna (Westheide, 1974), Odontosyllis fulgurans (Audouin & Milne Edward, 1833), Opisthodonta mitchelli Kudenov & Harris, 1995, Pionosyllis articulata Kudenov & Harris, 1995, Sphaerosyllis (S.) californiensis Hartman, 1966 and Syllides cf. reishi Dorsey, 1978. The family Syllidae is represented in the Coiba National Park by 14% of cosmopolitan species, 14% of circumtropical species, 22% of Atlantic and Pacific species and 25% of Pacific species restricted to warm waters. In samples of dead coral the dominant species are S. armillaris (Muller, 1771) and S. gracilis (Campoy, 1982); in samples of telestaceans Grubeosyllis concinna dominates.
