During the studies on trematode fauna of birds from Lower Silesia, the rare species--Urotocus rossitensis (Mühling, 1898)--was found. It parasitized in the bursa Fabricii of Sylvia borin, Erithacus rubecula and Turdus philomelos, and in the cloaca of Turdus merula. All these birds are new hosts for U. rossitensis which was recorded for the first time in Poland. It is worth mentioning that the localization of this trematode in the cloaca of T. merula is nontypical, since the parasite has underdeveloped suckers. Morphological and biometrical data give us new information about variability of U. rossitensis. They allow the author to support Williams' (1960) proposition to include U. fusiformis McIntosh, 1935 and U. tholonetensis Timon-David, 1955 among the synonyms of Urotocus rossitensis (Mühling, 1898).
在对下西里西亚鸟类吸虫区系的研究过程中,发现了珍稀物种——罗氏尿殖吸虫(Urotocus rossitensis,Mühling,1898年)。它寄生于褐柳莺(Sylvia borin)、欧亚鸲(Erithacus rubecula)和歌鸫(Turdus philomelos)的法氏囊中,以及乌鸫(Turdus merula)的泄殖腔内。所有这些鸟类都是罗氏尿殖吸虫的新宿主,该吸虫在波兰首次被记录。值得一提的是,这种吸虫在乌鸫泄殖腔内的定位是非典型的,因为该寄生虫的吸盘发育不全。形态学和生物测量数据为我们提供了有关罗氏尿殖吸虫变异性的新信息。这些数据使作者能够支持威廉姆斯(1960年)的提议,即将梭形尿殖吸虫(Urotocus fusiformis,McIntosh,1935年)和托洛内特尿殖吸虫(Urotocus tholonetensis,Timon-David,1955年)列入罗氏尿殖吸虫(Urotocus rossitensis,Mühling,1898年)的同义词中。
