During our investigations on the parasitofauna of birds from Lower Silesia, the trematode Leyogonimus postgonoporus was encountered twice: from Turdus merula and Scolopax rusticola. The morphological details and measurements of this rare trematode are described and compared with the literature data. L. postgonoporus is a new species for the parasitofauna of Poland and Scolopax rusticola appears to be a new definitive host species for this trematode.
