From a study of 124 skates (Raja radiata Donovan, 1808) in the Canadian Atlantic Ocean, Echeneibothrium canadensis n.sp., is described, and the nomenclatural confusion of this species with E. variabile Van Beneden, 1849 is discussed. Echeneibothrium canadensis n.sp. is most closely related to E. variabile and other members of the genus with a large, robust myzorhynchus but is differentiated by possessing 12 distinct loculi within each bothridium, a large robust myzorhynchus, 18-26 testes per proglottis, and an armed cirrus and vitellaria extending posterior to the ovary.
