Seven new species of Urocleidoides (Monogenea: Dactylogyridae) from Brazilian fishes supported by morphological and molecular data

摘要: Seven new species of Urocleidoides from the gills and skin nine Neotropical fish hosts (Anostomidae, Parodontidae, Gymnotidae) are described: digitabulum n. sp. on Leporinus friderici, octofasciatus, Megaleporinus elongatus (Anostomidae); solarivaginatus L. striatus falxus sapucaiensis M. elongatus; tenuis Apareiodon piracicabae affinis (Parodontidae); sinus striatus, Schizodon nasutus, intermedius uncinus Gymnotus sylvius (Gymnotidae). paradoxus was also found in this study friderici included phylogenetic analysis. Molecular data (partial 28S rDNA mitochondrial cytochrome oxidase subunit I) were obtained for U. sp., The identification is amended herein to include all taxonomic modifications observed genus over time add characteristics present study. Phylogenetic analysis revealed (parasites anostomids) closely related tree topologies. Furthermore, described parasitized phylogenetically distant host (Characiformes Gymnotiformes), suggesting effect dynamic process ecological fitting.
