Monogenean Diversity on North American Catostomids (Cypriniformes): first insights into the phylogeny of the Pseudomurraytrematidae

Popis výsledku v původním jazyce

Catostomoidei (suckers) are one of four suborders of Cypriniformes with a holarctic distribution, with the greatest diversity occurring in North America (78 spp.) and only two species occurring in Asia. In order to address the considerable lack of information on monogeneans that parasitize these fishes, a thorough research survey was initiated in 2018. So far, nineteen catostomid species from nine US states, the Canadian province of Québec, and northern Mexico have been surveyed. Fourteen of them were positive for monogeneans of the Pseudomurraytrematidae. A total of 25 species across three genera of this family (Anonchohaptor, Icelanonchohaptor, Pseudomurraytrema) were collected from the gills and/or fins of the examined catostomid hosts. Pseudomurraytrema was the most diverse genus with fourteen species, followed by Anonchohaptor with seven species and Icelanonchohaptor with four species. The greatest species richness of monogeneans was recorded on Hypentelium nigricans (four species of Pseudomurraytrema). Phylogenetic reconstructions based on sequencing of nuclear genes (18S, ITS1 and 28S rDNA) demonstrated the monophyly of the Pseudomurraytrematidae with high support and showed that this family shares a close phylogenetic relationship with the Diplectanidae within the Dactylogyrinea. Pseudomurraytrema asiaticum from the Chinese sucker was in a basal position relative to all Nearctic pseudomurraytrematids. The Nearctic pseudomurraytrematids formed two clades, one including species of Pseudomurraytrema and the other including species of Anonchohaptor and Icelanonchohaptor. Terminal position of two species of Icelanonchohaptor within the clade containing Anonchohaptor spp., together with their morphological similarity to the latter genus, suggests synonymy between the two genera
