Specimens of Gorgoderina vitelliloba recovered from Rana temporaria and R. pipiens purchased in Eire are described using SEM. The microtopography is illustrated with particular emphasis on the type, number and arrangement of papillae. Significant differences in papillar arrangement were observed between the present specimens of G. vitelliloba from amphibians and that described earlier for the type species of Phyllodistomum from pike, Esox lucius , and Phyllodistomum from salmonids. The differences in papillae number and arrangement on the ventral sucker of G. vitelliloba and the Phyllodistomum species are interpreted as confirmation of their generic separation. The papillae types found are illustrated by SEM and discussed.
