Digenea of the fish, Macrourus holotrachys (Gadiformes, Macrouridae), fromthe North Scotia Ridge, sub-Antarctic

Four digenean species were found in fish of the species Macrourus holotrach ys caught at the North Scotia Ridge, sub-Antarctic. Gibsonia hastata Gaevsk aya et Rodyuk, 1988 and Lepidapedon lepidum Gaevskaya et Rodyuk, 1988 are r edescribed and figured based on new material and reexaminations of the type -specimens. L. lepidum possesses uroproct and therefore is transferred into the genus Paralepidapedon. Gonocerca phycidis Manter, 1925 and Lecithochir ium sp. (probably unknown species) are briefly described and figured. M. ho lotrachys is a new host for all these parasites.
