Dinoflagellates are considered as a very diverse group founded in most aquatic environments, however, despite the importance of this group, there are few works on them in the Caribbean Sea area, being the nearest in the Gulf of Mexico and the Vitória-Trindade submarine chain in Brazil. Hereby, Cladopyxis hemibrachiata is reported for first time in the Colombian Caribbean Sea, particularly found in the Seaflower Biosphere Reserve waters. The identification reports were part of an expedition carried out in September 2017 on Cayo Serranilla Island. Phytoplankton samples were collected by vertical drags from 200 m. deep using a 20 µm and 70 cm ring diameter conical net. In situ physical and chemical measured variables were typical of mesotrophic waters. As part of the confirmatory process of this new report for the Colombian Caribbean Sea, all aspects that many researchers have identified as fundamental to avoid mistakes in the identification of specimens, which are associated with the great similarity with Cladophyxis brachiolata were considered.
