Remarks. Machalska (1980) originally described Cyclocoelum polonicum Machalska, 1980 from two species of Turdus Linnaeus in Poland; however, we elected to use only those measurements from T. philomelos because of the large differences between the maximum egg size in specimens from this host (139 x 69) when compared to those from T. merula (150 x 81), which suggests that there may be two species of Morishitium represented in Table II of the original description. We did not name the second potential species because we had no access to the original material used in the description. This species as represented by the specimens from T. philomelos has an intertesticular ovary that forms nearly a straight line with the nearly tandem testes (Hyptiasminae), a postpharyngeal genital pore and the vitelline fields are not confluent posteriorly, placing it in Morishitium . Rudimentary oral sucker present—Machalska (1980).
