Abstract

The microhabitat and morphology of Grubea cochlear (Monogenea), a rare gill parasite of Atlantic mackerel (Scomber scombrus), were investigated for a sample of fourteen parasite individuals obtained from Lyme Bay, southern England. Grubea cochlear showed a preference for the inner hemibranch of the fourth gill arch, this localization contrasting with that of the related and sympatric species Kuhnia scombri. The morphology of G. cochlear in this sample differed slightly from some of the previously documented specimens, especially with regard to the number of small genital hooks and the relative size of the haptor. It is suggested that geographical morphological variation may occur in this species.
