Four digenean species were found in fish of the species Macrourus holotrachys caught at
the North Scotia Ridge, sub-Antarctic. Gibsonia hastata Gaevskaya et Rodyuk, 1988 and
Lepidapedon lepidum Gaevskaya et Rodyuk, 1988 are redescribed 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 Lecithochirium sp. (probably unknown species) are
and figured. M. holotrachys is a new host for all these parasites.
