A diatom species published by Ehrenberg (1854) under the name “Gallionella campylosira” has been observed and investigated in the light microscope (LM) from mica-strips in the Ehrenberg collection at the Natural History Museum, Humboldt University of Berlin (Germany). The raw material from which the mica-strips were made has also been observed and investigated in the scanning electron microscope (SEM). According to valve morphology it was found that this taxon belongs to the genus Aulacoseira Thwaites and so its formal transfer into this genus is proposed. The observed valve morphology and ultrastructure of this species are discussed and compared with those of related species to show valve pattern variability.
