B. liliana Lange-Bertalot and B. neglectissima Lange-Bertalot are freshwater species characterized by a high density of striae and individual striae, preferring calcium bicarbonate, oligotrophic, and alkaline lakes (Van de Vijver et al., 2021 a). B. styriaca (Grunow) R. Ross and B. zellensis (Grunow) Round & D. G. Mann were described by Grunow from Lake Erlauf (Van de Vijver et al., 2021 b). Based on an analysis of type material, as well as additional historic and modern specimens, it has been revealed that the majority of B. styriaca (Grunow) R. Ross populations from northern Europe belong to a different taxon (Van de Vijver et al., 2021 b). This taxon was originally described 70 years ago by Cleve-Euler as Anomoeoneis decipiens A. Cleve and has recently been recombined as B. decipiens (A. Cleve) Van de Vijver & Kusber. B. styriaca and B. decipiens can be differentiated based on several distinct morphological and ecological preferences (Van de Vijver et al., 2021 b). B. styriaca (Grunow) R. Ross is typically found in alkaline lakes and calciumbicarbonate, oligotrophic conditions, whereas B. decipiens prefers acidic environments. B. rylandsiana B. Van de Vijver, D. M. Williams & Ector, another European species of Brachysira, is distinguished from B. zellensis (Grunow) Round & D. G. Mann by features such as parallel valve margins, cuneately rounded apices, and various smaller ultrastructural details (Van de Vijver et al., 2021 b). The B. serians (Brébisson) Round & D. G. Mann and B. brebissonii R. Ross intermedia complex are typically found in oligotrophic and acidic habitats. The largest species within this complex are Brachysira serians (Brébisson) Round & D. G. Mann and B. wygaschii Lange-Bertalot, which exhibit distinct Voigt incompatibility. Although these species often coexist, they can be differentiated by their valve design and dimensions (Van de Vijver et al., 2021 c).	en	Ali, Naseri, Mostafa, Noroozi, Blanco, Saúl (2025): A checklist of diatoms with four endemic records and phytogeographical distribution from water habitats of Iran.
