Taxonomy not Cephalodella forficula (Ehrenberg) after Stenroos (1898)[=C. stenroosi Wulfert], Koste (1976 partim:pl.7, fig.2)[=Cephalodella tenuiseta (Burn)].
Koste's (1976) (op. cit.) trophi-figure of C. tenuiseta, sub C. forficula, has apparently been mislabeled.
The original combination under which this species name was established was hitherto taken to be Distemma forficula Ehrenberg, 1830. As Ehrenberg points out himself in his 'Infusionsthierchen' of 1838, however, Distemma forficula "ist der Furcularia forficula sehr nahe verwandt, hat aber 2 deutliche rothe Augen im Nacken" (p.449, cf. pl.56, fig.2). This clearly contrasts with the bright red frontal eye of Furcularia forficula, as described and figured by Ehrenberg in the same work (p.421, pl.48, fig.5). [details]
