Abstract
Intraspecific variation in internal morphological characters is substa ntial in many nemertean species, mainly due to the tendency for specim ens to contract during fixation. It is shown that variation within the type species for the genus Oerstedia, O. dorsalis (Abildgaard, 1806). encompasses all the character states that have been used to erect the two related genera Oerstediella and Paroerstedia. These genera are sy nonymized with Oerstedia, and the validity of species previously assig ned to these genera is discussed.
