ABSTRACT. Descriptions of Skrjabinoplagiorchis ondatrae and Troglotrema srebarni are given on the basis of specimens collected from muskrats living in the aquatic ecosystems of Lake Fertő and Lake Balaton. KEY WORDS: Trematoda, Skrjabinoplagiorchis ondatrae, Troglotrema srebarni, muskrat, Hungary. The American muskrat (Muridae: Ondatra zibethicus Linné, 1766) is a mammal widely distributed in its homeland, the North American continent. As a fur-bearing animal, it has been introduced to several Eurasian countries since the beginning of the present century. This prolific species, notorious for its migratory habits and excellent acclimatization, soon established itself in Bohemia (DOBRIS 1905) and spread to the neighboring countries as well. The muskrats settled in Hungary are descendants of the Bohemian stock. The first specimens were captured in 1914 on the banks of the river Lajta (Németjárfalu, 1914) and within a few years they spread all over the country. The North American origin of the muskrat, its remarkable distribution, semi-aquatic way of life, and the circumstance that its parasitic fauna has been subjected to investigation in almost all countries where the species occurs, offer every facility for studies aimed at answering the question what modifications in parasitism are likely to occur subsequent to changes in the host's habitat.
