N2  - Four taxa belonging to the complex of species around  Achnanthidium minutissimum  were found during the ongoing taxonomic revision of the Antarctic freshwater and limno-terrestrial diatom flora. Two taxa were previously described as  Achnanthidium lailae  and  A. sieminskae . Two others were formerly identified as  A. minutissimum  but detailed light and scanning electron microscopical observations revealed sufficient morphological differences compared to the type of  A. minutissimum , to justify their separation and description as new taxa:  Achnanthidium indistinctum  and  A. maritimo-antarcticum . The morphology and ecology of all four taxa are discussed comparing the species with morphologically similar taxa. The biogeographical consequences of the splitting of the former  A. minutissimum  complex in the Antarctic Region are discussed.
