Colurella: Lepadellidae: Ploima: Pseudotrocha: Monogononta: Eurotatoria
Taxonomic / nomenclatural notes:
• ?Colurella uncinata (Müller) after Dujardin (1841) [Ref.17194]
not Colurella obtusa (Gosse) after Pejler (1962 partim:figs.56,57) [Ref.11691] [=Colurella tesselata (Glascott)]; Pejler (1962 partim:fig.61) [Ref.11691] [=C. uncinata (Müller)]
• Taxonomic status of this polymorphic species and a number of infraspecific taxa included therein require further investigation. It probably represents a complex of cryptic species with narrower geographic ranges and/or ecological tolerances.
