Scrapings from several juvenile Chelonia mydas Linnaeus (green turtle) from Eastern Caribbean and adults from French Guiana allowed for the description of two small and relatively rare epizoic Tursiocola species (Bacillariophyta). Differences with the other eight Tursiocola species previously described are discussed here. Particular attention is given to the cingulum of the two new species and a conceptual key is proposed for Tursiocola species, based on the cingulum structure.

Keywords: Epizoic diatoms, sea turtles, Tursiocola, morphology, autecology
