Pseudopecoelus mccauleyi n. sp. (Opecoelidae: Opecoelinae) is described from the intestine of the bigfin eelpout, Lycodes cortezianus (Gilbert, 1890) (Perciformes: Zoarcidae), collected at 200–800 m depths in the Northeastern Pacific Ocean off Oregon and Vancouver Island, British Columbia. The new species is distinguished by possessing a unique combination of the following diagnostic characters: vitelline fields that extend to the posterior margin of the ventral sucker; a slender, tubular and… Expand
Description of a new species of Pseudopecoelus (Trematoda: Opecoelidae) with new records of trematodes of marine fishes from the Pacific coast of Mexico
New host and geographical records for 6 species of trematodes in marine fishes from Mexico and Pachycreadium gastrocotylum (Manter, 1940) Manter, 1954 is recorded for the first time in this country. Expand
Records of opecoeline species Pseudopecoelus cf. vulgaris and Anomalotrema koiae Gibson & Bray, 1984 (Trematoda, Opecoelidae, Opecoelinae) from fish of the North Pacific, with notes on the phylogeny of the family Opecoelidae.
The phylogeny does not support previous hypotheses about the monophyly of opecoelines with a uroproct, but supports the allocation of the six clades of Opecoelids and confirms the paraphyly of the group 'deep-sea Plagioporinae'. Expand
A new classification for deep-sea opecoelid trematodes based on the phylogenetic position of some unusual taxa from shallow-water, herbivorous fishes off south-west Australia
Two deep-sea opecoelids represented by sequence data, Neolebouria lanceolata and Podocotyloides brevis, remain inadequately accommodated and may require another new subfamily, but it is not yet clear which morphological and/or ecological characters would distinguish such a concept. Expand
Digenean parasites of deep-sea teleosts: A progress report
  • R. Bray
  • Medicine, Biology
  • International journal for parasitology. Parasites and wildlife
  • 2020
The understanding of the deep-sea digenean fauna is poor, and much further work over a much wider area is needed, with a major conclusion that it is distinctly less diverse that the equivalent fauna in shallow waters. Expand


Description of a new species of Podocotyle Dujardin, 1845 (Digenea: Opecoelidae: Plagioporinae) from the cusk-eel, Luciobrotula corethromycter Cohen, 1964 (Ophidiiformes: Ophidiidae), from the Gulf of Mexico and Caribbean Sea
The new species is distinguished by possessing a combination of the following features: an elongate oval body shape, a sucker width ratio of 1:1.9, deeply lobed and irregularly-shaped testes, a cirrus-sac that extends just in to the hindbody, a trilobed ovary and vitellarium that extend to the ventral sucker level.

Podocotyle nimoyi n. sp. (Digenea: Opecoelidae: Plagioporinae) and a re-description of Podocotyle pearsei Manter, 1934 from five species of deep-sea macrourids from the Gulf of Mexico and Caribbean Sea.
Two rare species of Podocotyle Dujardin, 1845 (Digenea: Opecoelidae) parasitizing five macrourid species inhabiting the deep waters of the northeastern Gulf of Mexico and Caribbean Sea off Panama areExpand
Six species of Lepidapedon Stafford, 1904 (Trematoda: Lepo-creadiidae) from deep-sea fishes.
Five new species and a new subspecies from deep-sea fishes off Oregon are placed in the genus Lepidapedon; all new species have excretory bladders which reach only to the posterior edge of the hind testis and a key to the short-bladdered members of the species is presented. Expand
Some digenetic trematodes from synaphobranchid eels.
Four trematodes, all new host records, were found in synaphobranchid eels from the continental slopes in the Gulf of Mexico and the Straits of Florida, found to be characterized by having scales and possessing either a single slitlike branchial aperture on the midline of the throat or two restricted ventral openings.

Two new species of Dinosoma Manter, 1934 (Trematoda: Hemiuridae) from deep-water macrourid fishes off the coast of Oregon.
Two new species from deep-water macrourid fishes taken off the coast of Oregon are reported, smaller than previously described forms, have less well-developed body scales, and have a muscular extension on the dorsal lip of the oral sucker. Expand
Pseudopecoelus sosoae sp. nov. and P. sewelli (Digenea, Opecoelidae) from the deep-sea fish Neoscombrops pacificus (Perciformes, Acropomatidae) off New Caledonia
A visual key based on 12 characters is presented, which shows that P. sosoae is distinguished from the most similar species by its very large eggs, elongate body and unlobed gonads. Expand
The deep-sea fish digenean genus Tellervotrema Gibson & Bray, 1982 (Opecoelidae: Plagioporinae): Re-evaluation of the type species, T. armstrongi Gibson & Bray, 1982 and T. beringi (Mamaev, 1965)
The generic diagnosis of Tellervotrema is amended to include circumcaecal vitelline follicles, and the presence of the viteLLine gap itself was found to be a more consistentdiagnostic generic character than the location of the resulting pair of distinct, isolated groups of vitella follicles created by the gap.

A new opecoelid trematode, Pseudopecoelus brayi sp. nov. from the shoulderbar soldierfish, Myripristis kuntee off Visakhapatnam coast, Bay of Bengal
A new species of opecoelid trematode, Pseudopecoelus brayi sp. nov. is reported from the holocentrid fish, Myripristis kuntee collected from off Visakhapatnam coast, Bay of Bengal. The new speciesExpand

The parasite community in halibut is more similar to those in other flatfishes than to Those in ecological analogs, suggesting that phylogeny is an important determinant as well. Expand
