After SEM studies we identified all of them as Eolimna archibaldii J.C. Taylor et Lange-Bert., which is currently regarded as endemic species to South Africa. Furthermore, the results of Principal Components Analysis of morphometric characters clearly demonstrated an overlap between the type material and European populations. Therefore this diatom cannot be considered endemic to South Africa. Moreover, E. archibaldii and a very similar species, E. becaresii are transferred to the genus Sellaphora. Our results confirm the benefit of SEM for verifying the identity of small-sized diatoms, especially for routine monitoring, and allow more precise ecological assessment.
