A checklist of literature records of the digenean parasites of macrourids from the world’s oceans is given. Where necessary annotations discussing the validity of the records are included. In addition, the records are listed under host. Tables summarising (I) the occurrence of parasites families, and (II) the geographical distribution of parasite species, are included. A figure illustrating the bathymetry of the parasite species is given. Information from 84 papers is summarised, in cluding records from 49 host-species and 13 genera. 68 identified species of adult worm, from 29 genera and 12 families and are reported. The most frequently reported families are the Lepocreadiidae, Derogenidae and Hemiuridae. The most frequently reported genus is Lepidapedon. Worms are reported from macrourids a depths between 150 and 7,000 m, with five identified species reported from the north-eastern Atlantic abyssal plain at a depth of about 4,850 m.

A total of 38 Coryphaenoides mediterraneus from the Charlie-Gibbs Fracture Zone (CGFZ), a part of the Mid-Atlantic Ridge (MAR), was studied for parasites and feeding ecology. Sixteen different parasite species were found, most of them belonging to the Digenea (6 species) and Nematoda (6). Twelve new host and 11 new locality records were established, and 8 deep-sea generalists and 5 deep-sea specialists were found. Twelve adult and 3 larval parasites occurred, with Allopodocotyle margolisi (Digenea), Tetraphyllidea indet. (Scolex pleuronectis, Cestoda) and Ascarophis longiovata (Nematoda) being the predominant species. These parasites reached a prevalence of 50.0%, 86.8% and 68.4% with an intensity of infection of 1–10, 1–91 and 1–74, respectively. The food consisted of crustaceans and cephalopods; no further prey items such as fish could be identified. Coryphaenoides mediterraneus demonstrates a parasite fauna similar to that of other deep-sea macrourids. No MAR-specific parasite species were found, and the collected helminths are common fish parasites of the North Atlantic deep-sea basin and the adjacent continental shelf regions. Only few larval epipelagic generalists such as ascaridoid nematodes were found, due to the deep origin of the studied fish between 1700–3500 m. The recorded species rich parasite fauna reflects the wide depth range and opportunistic feeding behaviour of C. mediterraneus on benthopelagic food. The recorded parasite species composition around the MAR appears to be similar to other deep-sea locations in the Atlantic Ocean, demonstrating the wide zoogeographical distribution of these deep-sea metazoans. Consequences of the MAR, the CGFZ and the homogeneous deep-sea environmental conditions for the parasite species distribution are discussed.

Pseudopecoelus mccauleyi n. sp. and Podocotyle sp. (Digenea: Opecoelidae) from the deep waters off Oregon and British Columbia with an updated key to the species of Pseudopecoelus von Wicklen, 1946 and checklist of parasites from Lycodes cortezianus (Perciformes: Zoarcidae)

In total, 60 fish specimens belonging to four families, Zoarcidae (19 specimens of three species), Liparididae (14 specimens of two species), Macrouridae (23 specimens of one species) and Rajidae (four specimens of two species), caught in the Weddell Sea were examined. A zoarcid, Lycodichthys dearborni, and both Rajidae, Bathyraja maccaini and Bathyraja sp., were not infected. Macrourus whitsoni was the most strongly infected (six digenean species found, prevalence 91.3%, mean abundance 10.13). Two zoarcids, Ophthalmolycus amberensis and O. bothriocephalus, were infected with Macvicaria longibursata; the former also with Aphanurus sp., Paraliparis antarcticus and P. trilobodon were infected with Steringophorus liparidis and Neolebouria terranovaensis, and Derogenes johnstoni, respectively. The check list of Digenea recorded in Antarctica in non- notothenioid fishes is given. Infected fishes belong to six families, Zoarcidae (7 digenean species found), Macrouridae (8), Muraenolepididae (9), Liparididae (5), Bathylagidae (one) and Rajidae (one). In total, 29 digenean species were found, of which 12 are common for Notothenioidei and other fishes, whereas 17 species are specific for non-notothenioid definitive hosts. Digenea belong to four higher taxa, Opecoelidae (10 species), Lepocreadiidae (10), Fellodistomidae (one) and Hemiuroidea (8).

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 Pąralepidapedon. Gonocerca phycidis Manter, 1925 and Lecithochirium sp. (probably unknown species) are briefly described and figured. M. holotrachys is a new host for all these parasites.

In total, 23 fishes caught at depth 625-1540 m were examined and 21 found to be infected with digeneans belonging to 6 species, 4 lepocreadiids in the intestine and 2 hemiuroids in the stomach. Three lepocreadiid species are described as new: Lepidapedon brayi sp. n., L. ninae sp. n. and Paralepidapedon awii sp. n. Some morphological data for other species are given. Postlepidapedon opisthobifurcatus (Zdzitowiecki, 1990) and Glomericirrus macrouri (Gaevskaya, 1975) are reported from the high Antarctic for the first time and in new hosts. Gonocerca phycidis Manter, 1925 is found in a new host. The total number of digenean species recorded in M. whitsoni increased from 2 to 8.
