Redescription of Diclidophoroides maccallumi (Monogenea: Diclidophoridae) from the gills of longfin hake, Phycis chesteri , from the Gulf of St. Lawrence
Diclidophoroides maccallumi is redescribed from the gills of longfin hake, Phycis chesteri, caught off the coast of Newfoundland in the Gulf of St. Lawrence. Specific characteristics such as the number of genital corona spines and morphometric measurements are within the range limits given in previo...

The detailed morphology of the clamp, the male genital terminalia, and the female reproductive system is presented.
