Bathycreadium brayi n. sp. is described based on specimens collected from the deep-sea greater forkbeard Phycis blennoides (Brünnich) (Gadiformes: Phycidae) in the Western Mediterranean. The new species is distinguished from B. flexicolle Kabata, 1961, B. elongata (Maillard, 1970) and B. nanaflexicolle Dronen, Rubec & Underwood, 1977 by the much smaller size of the body and most organs, the large (in relation to body length and width) ventral sucker and the distinctly more anterior extent of… 
The Pseudoplagioporinae, a new subfamily in the Opecoelidae Ozaki, 1925 (Trematoda) for a small clade parasitizing mainly lethrinid fishes, with three new species
A small group of relatively distinctive, Indo-West Pacific taxa reliably known almost entirely from emperor fishes, restricted to a clade of Holarctic, freshwater taxa, is proposed, whereas analyses of new genetic data find the pseudoplagioporines to form a distinct clade among a larger assemblage of marine taxa.
Revision of Neolebouria Gibson, 1976 (Digenea: Opecoelidae), with Trilobovarium n. g., for species infecting tropical and subtropical shallow-water fishes
A new opecoelid trematode is reported from fishes of the Lethrinidae, Lutjanidae and Nemipteridae off Lizard Island on the northern Great Barrier Reef, Australia, and shows strong similarity to several species of that genus, but is not consistent with the type-species, N. georgiensis Gibson, 1976, or others known from temperate/polar and/or deep-sea fishes.
Revision of Podocotyloides Yamaguti, 1934 (Digenea: Opecoelidae), resurrection of Pedunculacetabulum Yamaguti, 1934 and the naming of a cryptic opecoelid species
The revised concept of Podocotyloides requires a pedunculate ventral sucker, but also a uterine sphincter prior to the genital atrium, a petalloid cirrus appendage, restriction of the vitelline follicles to the hindbody, and for the excretory vesicle to reach to the level of theventral sucker.
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'.
The molecular phylogeny of the digenean family Opecoelidae Ozaki, 1925 and the value of morphological characters, with the erection of a new subfamily.
Many of the morphological characters were found to be homoplasious, but the characters defining the Helicometrinae and Opecoelinae, such as filamented eggs, reduced cirrus-sac and uterine seminal receptacle, are closely correlated with the inferred phylogeny.
Parasite diversity from two deep-sea fishes Phycis blennoides (Brunnich, 1768) and Phycis phycis (Linne, 1758), from the western Algerian coasts
Investigating the diversity of metazoan parasites from the western Algerian coasts indicated that these fish act as their definitive hosts, while cosmopolite species are present in the larval stage.
A new subfamily for a clade of opecoelids (Trematoda: Digenea) exploiting marine fishes as second-intermediate hosts, with the first report of opecoelid metacercariae from an elasmobranch
Metacercariae of trematodes belonging to the family Opecoelidae were collected from small fishes of the Great Barrier Reef: a blenniid, two gobiids, two labrids, three pomacentrids, a monacanthid, an
The parasite community of Phycis blennoides (Brünnich, 1768) from the Balearic Sea in relation to diet, biochemical markers, histopathology and environmental variables
The parasite community of P. blennoides was characterized by high abundance, richness and diversity, and Cysts of unknown etiology in fish gills were detected at higher prevalence than in any other fish from the same area.
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.
Raphidascaris (Raphidascaris) macrouri n. sp. (Nematoda: Anisakidae) from two deep-sea macrourid fishes in the Western Mediterranean: Morphological and molecular characterisations.
A new nematode species, Raphidascaris (Raphidascaris) macrouri n. sp. (Anisakidae), is described from male and female specimens found in the intestine, and occasionally in stomach and pyloric caeca,


Parasitisation by Bathycreadium elongatum (Digenea, Opecoelidae) in pyloric caeca of Trachyrincus scabrus (Teleostei, Macrouridae).
A novel process of transmural passive displacement of a digenean parasite was studied in the digestive tract of the roughsnout grenadier Trachyrincus scabrus, which is found in the northwestern
Molecular phylogenetic analysis of the Microphalloidea Ward, 1901 (Trematoda: Digenea)
It is demonstrated that the Microphalloidea, as represented by the present data-set, consists of three main clades corresponding to the families Lecithodendriidae, Microphallidae and Pleurogenidae + Prosthogonimidae.
The phylogeny of the Lepocreadioidea (Platyhelminthes, Digenea) inferred from nuclear and mitochondrial genes: Implications for their systematics and evolution
The phylogenetic relationships of representative species of the superfamily Lepocreadioidea were assessed, and it could not be demonstrated that a significant proportion of sites in the nad1 gene evolved under positive selection; this anomalous relationship therefore remains unexplained.
Digenean species diversity in teleost fish from a nature reserve off Corsica, France (Western Mediterranean), and a comparison with other Mediterranean regions
A more detailed analysis of the diversity of these parasites in sparid fishes indicates that the digenean diversity off Corsica is far greater than that in other parts of the Mediterranean.
Molecular identification of developmental stages in Opecoelidae (Digenea).
It is revealed that cercariae of the same species are able to infect more than one gastropod host species, suggesting that the specificity for the first intermediate host within the Digenea may be lower than previously thought.
The following two species are described as new : Bathycreadium biscayense and Steringophorus blackeri. Seven of the remaining species are described, these are Dolichoenterum longissimum Ozaki,
Twenty specimens of a trematode, hitherto undescribed, were found in Macurus fabricii caught off the coast of Iceland. They are described, figured and named in this paper.
MEGA5: molecular evolutionary genetics analysis using maximum likelihood, evolutionary distance, and maximum parsimony methods.
The newest addition in MEGA5 is a collection of maximum likelihood (ML) analyses for inferring evolutionary trees, selecting best-fit substitution models, inferring ancestral states and sequences, and estimating evolutionary rates site-by-site.
