Pinnularia sofia Van de Vijver & Le Cohu spec. nov., a new spine-bearing, chain-forming Pinnularia species from the sub-Antarctic region
The spine-bearing diatom Pinnularia sofia Van de Vijver & Le Cohn spec. nov. is described from the sub-Antarctic Heard Island. The morphology of this species was examined using the scanning electron microscopy (SEM). The most striking feature of the new taxon is the presence of three groups of w...
