Taxonomic / nomenclatural notes:
• Anuraea aculeata var. after Murray (1913) [Ref.17435]; ?Keratella valga var. asymetrica Barrois & Daday after Hauer (1937) [Ref.17258], K. valga (Ehrenberg) after Ahlstrom (1943 partim) [Ref.16986], Koste (1979 partim:fig.19) [Ref.17339].
not Keratella tropica (Apstein) after Ahlstrom (1943 partim:pl.42,figs.11,13) [Ref.16986], Olivier (1965) (cit. in Modenutti et al. (1998) [Ref.17417]) [=Keratella morenoi Modenutti, Diéguez & Segers].
• Specimen material from Colombo Lake sent by Apstein to Rousselet, and now deposited in the NHM London (NHM 1917.1.1.994) probably represents syntypic material (no types have been designated in the original publication).
