This is the first report of Labyrinthulomycetes for Argentina. Five strains of Thraustochytriales were isolated from both, a saline continental environment and an estuarial one from Argentina. The strains were identified as Thraustochytrium aff. antarcticum, Ulkenia aff. radiata and U. aff. visurgensis because the observations did not exactly fit the original descriptions in the morphological and ecological aspects. Se presentan y describen cinco cepas de Thraustochytriales aisladas de dos ambientes: uno salino continental y otro estuarial. Debido a que las observaciones no coincidieron exactamente con las descripciones originales, tanto en lo morfológico como en lo ecológico, las cepas se determinaron como Thraustochytrium aff. antarcticum, Ulkenia aff. radiata y U. aff. visurgensis. Estos registros constituyen las primeras citas de Labyrinthulomycetes para Argetnina.
