Abstract

MOLINA-ACEVEDO, Isabel C  and  LONDONO-MESA, Mario H. TEREBELLIDS (TEREBELLIDAE: POLYCHAETA: ANNELIDA) FROM ISLA FUERTE, COLOMBIAN CARIBBEAN. Bol. Invest. Mar. Cost. [online]. 2015, vol.44, n.2, pp.253-279. ISSN 0122-9761.

The family terebellidae has been poorly studied in colombia. The only available information on the family presented is in term of lists, which comprise 17 species occurring in the northeastern Colombian Caribbean. Taxonomic studies including detailed descriptions are none. This research focused on taxonomic evaluation of terebellids diversity from Isla Fuerte, Colombian Caribbean, as well as on the increasing the species knowledge for the southwestern region. Specimens from coralline rock and calcareum algae were collected and analyzed from seven beaches around the island. Six genera and ten species were found: Eupolymnia rullieri, Lanicola carus, Pista palmata, and Terebella verrilli have been already identified in the Colombian Caribbean; Polycirrus sp.1, Polycirrus sp.2 and Pista sp. remain undescribed due the lack of enough material justifing new species category. Finally, Loimia minuta, Pista cetrata and Polycirrus angeli are new records for Colombia. After this research, the number of recorded terebellid species increased to 20, and the species distributions were enlarged. Staining patterns and morphologic variation for each species are provided.
