A Redescription of Adult Phyllodistomum umblae (Fabricius) (Digenea, Gorgoderidae) from Salvelinus alpinus (L.) in Norway
Phyllodistomum umblae (Fabricius, 1780), originally described on the basis of specimens recovered from the ureter of Arctic char Salvelinus alpinus in Drangedalen, Norway, is here redescribed with both light (LM) and scanning electron microscope (SEM) from material obtained from the type host and ty...
