Remarks on subgenus

This is clearly a polyphyletic subgenus in terms of molecular data (Kieneke et al. 2008; Kånneby et al. 2012, 2013); it encompasses 84 nominal freshwater and 4 nominal marine species (Kieneke & Schmidt-Rhaesa 2015; Todaro 2018). Present in benthic, interstitial, periphytic and rarely also in semi-planktonic habitats (Kisielewski 1997a).
