The caryophyllidean tapeworms (Cestoda) of the genus Isoglaridacris Mackiewicz, 1965 are revised on the basis of the study of type specimens and newly collected material from suckers (Cypriniformes: Catostomidae) in North America. Molecular data reveal the presence of 14 lineages, each representing a separate species. An overview of all nominal species is provided, with updated information on their hosts, distribution and phylogenetic relationships. Isoglaridacris multivitellaria Amin, 1976 is excluded from Isoglaridacris, but its generic affiliation remains unclear, and it is considered incertae sedis. Homeomorpha mackiewiczi Dutton et Barger, 2014 from Minytrema melanops is transferred to Isoglaridacris as I. mackiewiczi (Dutton et Barger, 2014) new combination. Based on molecular and morphological data, four new species are described: Isoglaricris mattisi n. sp. from Moxostoma collapsum in South Carolina, USA, I. mcallisteri n. sp. from Erimyzon claviformis in Arkansas and Oklahoma, USA, I. mexicanus n. sp. from Moxostoma cf. austrinum in Chihuahua, Mexico, and I. floriani n. sp. from M. macrolepidotum in South Carolina. A key to the identification of all 16 valid species is provided. Isoglaridacris species exhibit strict host specificity, with most species parasitising only a single host species (strict specialists), while a few species occur in more than one species within the same host genus (congeneric specialists). The distribution range of Isoglaridacris species includes southern Canada, the United States and northwestern (nearctic) Mexico.

The caryophyllidean tapeworm Khawia armeniaca has long been regarded as an exceptionally widespread species within its genus, notable for its significant morphological variability. However, with the accumulation of molecular data from different fish hosts, K. armeniaca was suspected to represent a species complex. To clarify the true identity of these parasites, a comprehensive morphological and molecular study (using 18S, 28S and ITS2 ribosomal regions) of K. armeniaca tapeworms from barbels (Barbinae) across the Iberian Peninsula and the Middle East has been conducted. The results revealed two genetically distinct lineages within the K. armeniaca complex. The first lineage, found in Arabibarbus grypus, Barbus lacerta, Capoeta birunii, Carassobarbus luteus, Luciobarbus barbulus, L. esocinus and L. kersin in Iraq and Iran, is genetically congruent with K. armeniaca (Cholodkovsky, 1915), originally described from the Sevan khramulya (Capoeta sevangi) in Armenia. The second lineage, identified in Luciobarbus bocagei (type host), L. comizo and L. guiraonis from Portugal and Spain, is described as Khawia iberica n. sp. In addition to clear molecular divergence, K. iberica can be distinguished from K. armeniaca by notable morphological differences, including variations in the shape, structure and size of the ovary, the anterior extension of the vitelline follicles, the testes and several morphometric parameters.

Monogenea (Platyhelminthes), mainly gill and fin ectoparasites of fish, are often recognized as host specific and morphologically and ecologically diverse. These parasites exhibit high species diversity at the level of host species or individual fish specimens. Using case studies, especially those widely performed in Dactylogyrus parasitizing cyprinoid fish, this article presents current knowledge on the ecology and evolution of congeneric gill monogeneans. The important aspects of the ecology of congeneric monogeneans are highlighted, in particular: host specificity expressed at several host levels (from strict specificity to phylogenetic specificity), microhabitat specificity expressed by restricted positions on fish gills to facilitate intraspecific mating, and the link between microhabitat preference and morphological adaptation (i.e., sclerotized structures of the haptor) or reproductive isolation. From the evolutionary perspective, this study focused on the processes of the speciation and diversification of congeneric monogeneans, highlighting the role of host switch as the most prominent coevolutionary event, accompanied in some cases mostly by intrahost speciation or cospeciation, as revealed by cophylogenetic studies. Here, important knowledge on evolutionary patterns of host specificity, microhabitat specificity, and morphological adaptation is presented. Host-specific monogeneans may represent an important tool for studying the historical biogeography of their hosts. Specifically, in the case of freshwater fish hosts exhibiting disjunctive distribution, they reflect both historical and contemporary contacts. The role of host-specific congeneric monogeneans in revealing historical intercontinental and intracontinental contacts between freshwater fish is highlighted. Finally, the importance of the role of genetic coadaptation, limiting the presence of host-specific monogeneans in hybrid fish, is emphasized.

TITLE: Monogènes spécifiques à leur hôte parasitant les poissons d’eau douce : écologie et évolution des associations hôtes-parasites. ABSTRACT: Les Monogènes (Plathelminthes), principalement ectoparasites des branchies et des nageoires des poissons, sont souvent reconnus comme spécifiques à leur hôte et diversifiés morphologiquement et écologiquement. Ces parasites présentent une grande diversité d’espèces au niveau des espèces hôtes ou des spécimens individuels de poissons. À l’aide d’études de cas (en particulier celles largement réalisées chez les Dactylogyrus parasitant les poissons cyprinoïdes), les connaissances actuelles sur l’écologie et l’évolution des monogènes branchiaux congénères sont présentées. Les aspects importants de l’écologie des monogènes congénères sont mis en évidence, en particulier la spécificité à l’hôte exprimée à plusieurs niveaux de l’hôte (de la spécificité stricte à la spécificité phylogénétique), la spécificité du microhabitat exprimée par des positions restreintes sur les branchies des poissons pour faciliter l’accouplement intraspécifique, et le lien entre la préférence du microhabitat et l’adaptation morphologique (c’est-à-dire les structures sclérifiées du hapteur) ou l’isolement reproductif. Du point de vue évolutif, l’étude a été concentrée sur les processus de spéciation et de diversification des monogènes congénères, soulignant le rôle du changement d’hôte comme l’événement coévolutif le plus important, accompagné surtout dans certains cas de spéciation ou de cospéciation intra-hôte, comme le révèlent les études cophylogénétiques. Des connaissances importantes sont présentées ici sur les modèles évolutifs de spécificité d’hôte, de spécificité de microhabitat et d’adaptation morphologique. Les monogènes spécifiques à l’hôte peuvent représenter un outil important pour étudier la biogéographie historique de leurs hôtes. Plus précisément, dans le cas des poissons d’eau douce hôtes présentant une distribution disjonctive, ils reflètent à la fois des contacts historiques et contemporains. Le rôle des monogènes congénères spécifiques à leur hôte dans la révélation des contacts intercontinentaux et intracontinentaux historiques entre poissons d’eau douce est mis en évidence. Enfin, l’importance du rôle de la coadaptation génétique limitant la présence de monogènes spécifiques à l’hôte chez les poissons hybrides est soulignée.

The freshwaters of Iraq harbour a high diversity of endemic and phylogenetically unique species. One of the most diversified fish groups in this region is cyprinoids, and although their distribution is relatively well known, their monogenean parasites have only rarely been investigated. Herein, we applied an integrative approach, combining morphology with molecular data, to assess the diversity and phylogeny of cyprinoid-associated monogenean parasites. A total of 33 monogenean species were collected and identified from 13 endemic cyprinoid species. The highest species diversity was recorded for Dactylogyrus (Dactylogyridae, 16 species) and Gyrodactylus (Gyrodactylidae, 12 species). Four species of Dactylogyrus and 12 species of Gyrodactylus were identified as new to science and described. Two other genera, Dogielius (Dactylogyridae) and Paradiplozoon (Diplozoidae), were represented only by 4 and 1 species, respectively. Phylogenetic analyses of the Dactylogyrus and Gyrodactylus species revealed that the local congeners do not form a monophyletic group and are phylogenetically closely related to species from other regions (i.e. Europe, North Africa and Eastern Asia). These findings support the assumption that the Middle East served as an important historical crossroads for the interchange of fauna between these 3 geographic regions.

Despite the high diversity of freshwater fishes in the Nearctic region, little is known about the composition of their parasite communities. We addressed the diversity of viviparous monogeneans of Gyrodactylus parasitizing highly diversified cypriniform fish inhabiting Nearctic watersheds. Nowadays, a thorough assessment of Gyrodactylus spp. diversity requires both morphological traits and genetic data. A combination of taxonomically important haptoral features and sequences of the ITS regions and 18S rDNA revealed 25 Gyrodactylus spp. parasitizing two catostomid and 15 leuciscid species sampled in six distinct localities in the United States and Canada. These include ten Gyrodactylus species recognized as new to science and described herein (G. ellae n. sp., G. hamdii n. sp., G. hanseni n. sp., G. huyseae n. sp., G. kuchtai n. sp., G. lummei n. sp., G. mendeli n. sp., G. prikrylovae n. sp., G. scholzi n. sp., and G. steineri n. sp.), seven already known species, and finally eight undescribed species. Overall, Nearctic Gyrodactylus spp. exhibited haptoral morphotypes known from fish hosts worldwide and those apparently restricted to Nearctic Gyrodactylus lineages like the typical ventral bar with a median knob and a plate-like membrane, or the additional filament attached to the handles of marginal hooks. The integrative approach further evidenced possible ongoing gene flow, host-switching in generalist Gyrodactylus spp., and regional translocation of monogenean fauna through fish introductions. The study highlights the hitherto underexplored morphological and genetic diversity of viviparous monogeneans throughout the Nearctic region.

TITLE: Révélation de la diversité cachée des communautés de Gyrodactylus (Monogenea, Gyrodactylidae) des poissons hôtes néarctiques Catostomidae et Leuciscidae (Teleostei, Cypriniformes), avec la description de dix nouvelles espèces. ABSTRACT: Malgré la grande diversité des poissons d’eau douce dans la région néarctique, on sait peu de choses sur la composition de leurs communautés de parasites. Nous avons abordé la diversité des monogènes vivipares du genre Gyrodactylus parasitant des poissons cypriniformes très diversifiés habitant les bassins versants néarctiques. De nos jours, une évaluation approfondie de la diversité de Gyrodactylus spp. nécessite à la fois des traits morphologiques et des données génétiques. Une combinaison de caractéristiques haptorales et de séquences taxonomiquement importantes des régions ITS et de l’ADNr 18S a révélé 25 espèces de Gyrodactylus sur deux espèces de catostomidés et 15 espèces de leuciscidés échantillonnées dans six localités distinctes aux États-Unis et au Canada. Celles-ci comprennent dix espèces de Gyrodactylus reconnues comme nouvelles pour la science et décrites dans cette étude (G. ellae n. sp., G. hamdii n. sp., G. hanseni n. sp., G. huyseae n. sp., G. kuchtai n. sp., G. lummei n. sp., G. mendeli n. sp., G. prikrylovae n. sp., G. scholzi n. sp. et G. steineri n. sp.), sept espèces déjà connues et enfin huit espèces non décrites. Dans l’ensemble, les espèces de Gyrodactylus néarctiques présentaient des morphotypes haptoraux connus chez les poissons hôtes du monde entier et ceux apparemment limités aux lignées néarctiques de Gyrodactylus comme la barre ventrale typique avec un bouton médian et une membrane en forme de plaque, ou le filament supplémentaire attaché aux poignées des crochets marginaux. L’approche intégrative a en outre mis en évidence le flux de gènes en cours, le changement d’hôte chez les espèces de Gyrodactylus généralistes et la translocation régionale de la faune monogène par l’introduction de poissons. L’étude met en évidence la diversité morphologique et génétique jusqu’ici sous-explorée des monogènes vivipares dans toute la région néarctique.

Ribosomal DNA sequences are currently available for 32 morphologically recognized species of Dactylogyrus parasitizing Nearctic cypriniforms, but only 16 of them are assigned to nominal species. Herein, morphological data on 28 of the 32 species are provided, together with comments on their phylogenetic relationships in the context of the morphology of taxonomically important structures. Seven new species of Dactylogyrus are described from five species of leuciscids and one species of catostomids, as follows: D. aduncus n. sp. from Campostoma spadiceum, D. cloutmani n. sp. from Luxilus chrysocephalus isolepis, D. cornifrons n. sp. from Cyprinella venusta, D. fimbratus n. sp. from Rhinichthys cataractae, D. mcallisteri n. sp. from Semotilus atromaculatus, and D. chieni n. sp. and D. haneki n. sp. from Hypentelium nigricans. Four previously described species of Dactylogyrus, D. atromaculatus from S. atromaculatus, D. eos from C. neogaeus, D. parvicirrus from Notemigonus crysoleucas and D. perlus from L. c. isolepis, are redescribed and/or figured. As for the remaining 17 species, only the male copulatory organs (MCOs) taken from the respective hologenophores are illustrated. On the basis of phylogenetic analyses, two main clades of Nearctic Dactylogyrus were recognized and supported by the different morphology of the MCO. The first one included 22 strictly Nearctic species sharing the same MCO type with Dactylogyrus spp. parasitizing cyprinids likely of Asian origin. The second clade encompassed Dactylogyrus spp. with diverse MCO morphology and was placed in the sister position to Dactylogyrus spp. parasitizing European leuciscids and North-West African cyprinids.

TITLE: Espèce néarctique de Dactylogyrus (Platyhelminthes, Monogenea) parasitant des poissons cypriniformes dans un contexte de morphologie et phylogénie, avec description de sept nouvelles espèces. ABSTRACT: Des séquences d’ADN ribosomal sont actuellement disponibles pour 32 espèces morphologiquement reconnues de Dactylogyrus parasitant les cypriniformes néarctiques, mais seulement 16 d’entre elles sont attribuées à des espèces nominales. Ici, des données morphologiques sur 28 des 32 espèces sont fournies avec des commentaires sur leurs relations phylogénétiques dans le contexte de la morphologie des structures taxonomiquement importantes. Sept nouvelles espèces de Dactylogyrus sont décrites à partir de cinq espèces de leuciscidés et d’une espèce de catostomidés, comme suit : D. aduncus n. sp. de Campostoma spadiceum, D. cloutmani n. sp. de Luxilus chrysocephalus isolepis, D. cornifrons n. sp. de Cyprinella venusta, D. fimbratus n. sp. de Rhinichthys cataractae, D. mcallisteri n. sp. de Semotilus atromaculatus et D. chieni n. sp. et D. haneki n. sp. de Hypentelium nigricans. Quatre espèces de Dactylogyrus précédemment décrites, D. atromaculatus de S. atromaculatus, D. eos de C. neogaeus, D. parvicirrus de Notemigonus crysoleucas et D. perlus de L. c. isolepis, sont redécrites et/ou figurées. Comme pour les 17 espèces restantes, seuls les organes copulateurs mâles (OCM) prélevés sur les hologénophores respectifs sont illustrés. Sur la base d’analyses phylogénétiques, deux clades principaux de Dactylogyrus néarctiques ont été reconnus et soutenus par des morphologies différentes de l’OCM. Le premier comprenait 22 espèces strictement néarctiques partageant le même type d’OCM que les Dactylogyrus spp. parasitant des cyprinidés probablement d’origine asiatique. Le deuxième clade comprenait des Dactylogyrus spp. avec diverses morphologies d’OCM et était placé en position sœur des Dactylogyrus spp. parasitant les leuciscidés européens et les cyprinidés d’Afrique du Nord-Ouest.

Proteocephalid tapeworms of frogs of the family Ranidae ('true' frogs) are reviewed with emphasis on their species diversity, host specificity and geographical distribution. New molecular data (nuclear lsrDNA and mitochondrial COI sequences) are presented for tapeworms of four species of ranid frogs in North America, including the poorly known Ophiotaenia saphena Osler, 1931 of Rana clamitans Latreille and R. catesbeiana (Shaw), which is redescribed using new material from Arkansas, USA. Tapeworms of R. sphenocephala (Cope) and R. pipiens Schreber, the latter previously identified as O. saphena, represent another, putative new species, but are not formally described due to insufficient available material. Proteocephalus papuensis Bursey, Goldberg et Kraus, 2008 from Sylvirana supragrisea (Menzies) is transferred to Ophiotaenia La Rue, 1911 as a new combination. After a critical review of the literature, only nine nominal species of Ophiotaenia are recognised as valid, which is in contrast to the large number of ranid frogs (> 440 spp.). The reasons for this striking disparity are briefly discussed, and a key based on morphology is presented for the identification of all species of Ophiotaenia from the Ranidae. Molecular data are available for only two taxa from North America that form a monophyletic group. The relationships among tapeworms of ranid frogs occurring in other zoogeographical regions are not yet known. The taxonomic status of Batrachotaenia Rudin, 1917, which was erected to accommodate proteocephalids from amphibians, is also discussed. To facilitate future studies, a tabulated summary of all 32 species of proteocephalids belonging to three genera reported from amphibians (frogs and salamanders) is presented, with information on their hosts, distribution, and taxonomically important characters, including key measurements.

BACKGROUND: Several hypotheses have been proposed to explain parasite infection in parental species and their hybrids. Hybrid heterosis is generally applied to explain the advantage for F1 generations of hybrids exhibiting a lower level of parasite infection when compared to parental species. Post-F1 generations often suffer from genetic incompatibilities potentially reflected in the higher level of parasite infection when compared to parental species. However, the presence of specific parasites in an associated host is also limited by close coevolutionary genetic host-parasite associations. This study focused on monogenean parasites closely associated with two leuciscid fish species-common bream and roach-with the aim of comparing the level of monogenean infection between parental species and hybrids representing two F1 generations with different mtDNA and two backcross generations with different cyto-nuclear compositions. RESULTS: Monogenean infection in F1 generations of hybrids was lower when compared to parental species, in line with the hybrid heterosis hypothesis. Monogenean infection in backcross generations exhibited similarities with the parental species whose genes contributed more to the backcross genotype. The distribution of monogeneans associated with one or the other parental species showed the same asymmetry with a higher proportion of roach-associated monogeneans in both F1 generations and backcross generation with roach in the paternal position. A higher proportion of common bream-associated monogeneans was found in backcross generation with common bream in the paternal position. CONCLUSIONS: Our study indicated that cyto-nuclear incompatibilities in hybrids do not induce higher monogenean infection in backcross generations when compared to parental species. However, as backcross hybrids with a higher proportion of the genes of one parental taxon also exhibited high level of this parental taxon-associated parasites, host-parasite coevolutionary interactions seem to play an obvious role in determining the level of infection of host-specific monogeneans in hybrids.

The tapeworms of fishes (Chondrichthyes and Actinopterygii) account one-third (1670 from around 5000) of the total tapeworm (Platyhelminthes: Cestoda) species diversity. In total 1186 species from 9 orders occur as adults in elasmobranchs (sharks, rays and chimaeras), and 484 species from 8 orders mature in ray-finned fishes (referred to here as teleosts). Teleost tapeworms are dominated by freshwater species (78%), but only 3% of elasmobranch tapeworms are known from freshwater rays of South America and Asia (Borneo). In the last 2 decades, vast progress has been made in understanding species diversity, host associations and interrelationships among fish tapeworms. In total, 172 new species have been described since 2017 (149 from elasmobranchs and 23 from teleosts; invalidly described taxa are not included, especially those from the Oriental region). Molecular data, however, largely limited to a few molecular markers (mainly 28S rDNA, but also 18S and cox1), are available for about 40% of fish tapeworm species. They allowed us to significantly improve our understanding of their interrelationships, including proposals of a new, more natural classification at the higher-taxonomy level (orders and families) as well as at the lower-taxonomy level (genera). In this review, we summarize the main advances and provide perspectives for future research.

Due to the safe "off label" use of selected antiparasitic drugs in fish, we assessed the effects of a therapeutic bath with levamisole (50 mg/l), fenbendazole (25 mg/l), and ivermectin (0.031 mg/l) on the haematological and biochemical blood indices, oxidative and antioxidant variables, and gill histology of the common carp (Cyprinus carpio). Levamisole did not affect the haematological profile, but significantly increased (P < 0.01) the plasma glucose, lactate, and ammonia concentrations, alkaline phosphatase, and alanine aminotransferase activities, TBARS (muscle, liver), total superoxide dismutase activity (muscle), and catalase activity (liver) and significantly decreased (P < 0.01) plasma aspartate aminotransferase and glutathione reductase activity (gill, liver, muscle). Ivermectin led to a significantly (P < 0.01) greater muscle total superoxide dismutase activity compared to the controls, whereas the haematological and biochemical indices remained unchanged. On the other hand, fenbendazole did not affect the haematological or biochemical indices, and the oxidative stress parameters and antioxidant indices did not differ from the controls. The bath in FBZ can be recommended for safe antiparasitic treatment in carp.
