Spirotaenia beijerinckii Coesel (2002: 72) ( Figs. 5 View FIGURES 1–10 , 12 View FIGURES 11–18 )
Cells 5–8 times longer than wide, fusiform with narrowly apices, chloroplast ribbon-shaped, parietal, constituted by a single loosely twisted helical ribbon, with two tiny reddish dots at each end. Cell length 25–42 μm, breadth 4.5–5 μm.
Material examined: Brazil, Bahia State, municipality of Uruçuca, Serra Grande, Parque Estadual Serra do Conduru , 20/IV/2023, 14°29’36” S 39°08’13” W, B. F GoogleMaps . Souza ( HUESC 26220 ) .
Ecology: pond; periphyton associated to aquatic macrophytes, including Eleocharis sp. ; abiotic variables of water: pH 6.4, temperature 32.4 ºC, conductivity 24 μS/cm, TDS 12 ppm, ORP 177 mV.
Distribution: Europe: Netherlands, Germany, United Kingdom (Brook & Williamson 2011, Guiry & Guiry 2023); South America: Brazil (present study).
Note: Spirotaenia beijerinckii is a species that has only been documented in northern hemisphere countries so far. It typically inhabits oligotrophic and shallow environments characterized by acidic conditions ( Coesel & Meesters 2007). Its prominent characteristic is the presence of two small red dots at each end of the chloroplast. This coloration may lead to confusion with S. erythrocephala , which can be distinguished by its more rounded cell poles and a continuously reddish chloroplast end, lacking the two small red dots found in S. beijerinckii .
