Resumen
From the observation of micropreparations of diatoms of epiphytic habits, deposited as reference material in the collection of macroalgae Germán Bula-Meyer, from the Centro de Colecciones Biológicas de Universidad del Magdalena, we obtained the first record of the benthic diatom Chrisanthemodiscus floriatus Mann 1925, (Chrysanthemodiscaceae), to the Colombian Caribbean, in the Bay of Cinto in the Tayrona National Park , Magdalena-Colombia; its distribution known so far was in the northern hemisphere between 5 and 30°Citas
