| Popis | Neotropical region is a highly diverse area for both fishes and their respective parasites, still the extent of its diversity it is far from being well known. Anacanthorus Mizelle and Price, 1965 is a highly diversified genus of monogenean parasites in Neotropical fishes, mainly characins. Parasitological surveys of serrasalmid fish (Myleus schomburgkii, Serrasalmus maculatus and S. marginatus) in the Xingu River, a tributary of the Amazon River, Pará, and in the Miranda River, Mato Grosso do Sul revealed the presence of two unidentified species of Anacanthorus. Both species of Anacanthorus were compared with the previously described species parasitizing serrasalmids and both can be distinguished from their congeners mainly by the copulatory complex. Anacanthorus genus is characterized by having anchors modified as 4A hooks and a J-shaped MCO. Currently this genus includes 73 valid species, 37 described within serrasalmids. The records of two new species of this well studied group of monogeneans suggests a high level of speciation and diversification within this genus but further studies are necessary to reinforce this hypothesis. The data obtained herein increases our knowledge on the diversity, distribution and host specificity of the members of this genus. |
