In July-August of 2005-2008, 47 digenean trematodes were examined from 7 specimens of the common sandpiper, Actitis hypoleucos (L., 1758). The digeneans were collected during a study on the food composition of the common sandpiper. The research was conducted near Lisewo Malborskie (near Tczew, Zuławy Wiślane, Gdańsk sea-coast), at a resting site on the birds' migration route. The foods ingested were extracted from live birds by draining their alimentary tracts with a nasogastric tube. Two digenean species were identified: Plagiorchis nanus Rudolphi, 1802 (Plagiorchiidae) and Leucochloridium perturbatum Pojmańska, 1969 (Leucochloridiidae). Actitis hypoleucos is the host for these new records in Poland. The P. nanus individuals isolated from A. hypoleucos differed in terms of the visible uterus and the extent of the vitellaria in the posterior part of the body.
