Molecular phylogeny of two Rhinoxenus species (Monogenea: Dactylogyridae) from the nasal cavities of serrasalmids (Characiformes: Serrasalmidae) from Brazil

Phylogenetic position of Ancyrocephalus (sensu lato) curtus Achmerov, 1952 (Monopisthocotylea, Dactylogyridae), a parasite of fish Perccottus glenii Dybowski, 1877(Gobiiformes: Odontobutidae)

“…Molecular data are available only on three species of Ancyrocephalus sensu lato: Ancyrocephalus paradoxus Creplin, 1839, Ancyrocephalus percae Ergens, 1966, andAncyrocephalus mogurndae (Yamaguti, 1940). Phylogenetic analyses based on these data have shown that Ancyrocephalus sensu stricto, as proposed by Bychowsky and Nagibina (1970) for A. paradoxus (type) and A. percae from freshwater Palaearctic percid fishes, appears to be a natural taxon (Mathews et al 2021;Kmentová et al 2022;Osaki-Pereira et al 2023). At the same time, A. mogurndae clusters with representatives of Eutrianchoratus Paperna, 1969, Gobioecetes Ogawa & Ito, 2017, Heteronchocleidus Bychowsky, 1957, Pseudodactylogyrus Gussev, 1965, and Trianchoratus Price & Berry, 1966, confirming the polyphyly of Ancyrocephalus sensu lato (Wu et al 2006;Mendoza-Palmero et al 2015;Kmentová et al 2022).…”
