Abstract

Species belonging to the genus Tryblionella are important members of the diatom assemblages of benthic environments such as tidal flats. Their proper identification is thus of great importance in terms of taxonomy, ecology, as well as environmental sciences. However, many species of the genus have been neglected and/or misidentified during diatom studies of Korean tidal flats possibly due to the small size of the species. Lack of proper references for the identification of the species is also noted. To better understand the diversity of Tryblionella species, sediment samples were taken from various tidal flats of the Yellow Sea. Light microscope (LM) and scanning electron microscope (SEM) observations have shown the presence of Tryblionella adducta and T. hyalina, which have not been previously reported from Korean tidal flats. The former was found mostly from sand flats and the latter from mudflats. It is expected that the present study would contribute to a better understanding of the diversity and ecology of benthic diatoms of the Korean tidal flats.
