摘要

The current study aims to enhance the understanding of the distribution and morphology of the diatom Entomoneis paludosa W SMITH 1853 in African waters. The type material of Entomoneis paludosa (W SMITH) REIMER was examined using light and scanning electron microscopy and the morphological characters were compared with new specimens sampled from a temperate river in South Africa. The wider distribution of this taxon on the African continent is discussed, and its relationship to water quality variables.
