I' 



Zonorchis Travassos, 1944, as a valid genus for the reception of certain 

 species formerly included in the genera Eurytrema and Platynosomum, 

 with the members of the genus Zonorchis differing from the remaining 

 species of their respective generic groups in (1) the relatively large 

 i acetabulum in comparison to the size of the oral sucker; (2) the more 

 forward position of the genital pore; and (3) the extent and rounded 

 rather than dendritic follicles of the vitellaria.
