First finding of a genus Haslea Simonsen in Serbia and new diatom taxa for the country's flora in extreme and unique habitats in the Vojvodina Province

Salt habitats are extreme and unique environments found from Austria through Hungary to the Vojvodina Province in Serbia. In our study, we investigated eight saline habitats (channeled salt marshes, moist salt meadows and saline ponds), from which we collected plankton, epipelic and epiphytic diatoms. Seventeen diatom taxa new for the Serbian diatom flora were recorded. In addition, the genus Haslea, with one species (H. spicula), was recorded for the first time in Serbia. The identified taxa were sporadic or rare in the samples.
