Abstract
Species of the diatom genus Thalassiosira are an important component of the marine phytoplankton all over the world, and the Mexican Pacific Ocean planktonic flora is also rich in species of this genus. In this study 37 net plankton samples from the Gulf of Tehuantepec, Mexico were analyzed, yielding 23 taxa of the genus. Most of the species were studied using combined light and electron microscopy. New records for the Mexican Pacific Ocean are Thalassiosira hendeyi, T. intrannula, T. pseudonana, T. tenera and T. visurgis. The species of Thalassiosira recorded here seem to indicate that the Gulf of Tehuantepec represents a subtropical zone at least in one period of the year.
