Abstract
One hundred and eleven Lepidapedon elongatum-like worms from five gadiform fish species in the North Atlantic are compared using multivariate analyses of 22 metrical features. A principal component analysis followed by a discriminant analysis indicate multivariate morphological differences between worms in the different hosts. It is argued that the forms in the five host species, Gadus morhua, Onogadus argentatus, Trachyrhynchus trachyrhynchus, Coryphaenoides (Nematonurus) armatus and Lepidion eques, should be considered separate oioxenic species.
