Ten species of red macroalgae are newly reported for the Seaflower International Biosphere Reserve in the Caribbean Sea. Of these taxa, four have been previously reported for the Colombian Caribbean: Dohrniella antillarum, Halydictyon mirabile, Taenioma nanum, and Aglaothamnion cordatum. The remaining six species are new records for the country: Callithamniella tingitana, Frikkiella searlesii, Lejolisia exposita, Melanothamnus gorgoniae, Monosporus indicus, and Wrangelia gordoniae. The algal material was collected in coral reef habitats (9-17 m depth), and all species but one are diminutive algae growing mostly on coral rubble or as epiphytes on larger algae. Their morphological features are discussed.

Keywords : Caribbean; Colombia; Frikkiella; red algae; Wrangelia; Callithamniella; Lejolisia; Melanothamnus; Monosporus.
