“…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).…”

The genus Ancyrocephalus sensu lato is a large assemblage of species of dactylogyrid monopisthocotyleans without clear taxonomic boundaries. Despite an urgent need for revision, only three representatives of this taxon have been molecularly characterised so far. We found specimens of Ancyrocephalus curtus, a previously non-genotyped species, in gills of Perccottus glenii caught in the River Syumnyur, Amur Basin, Russia. The aim of this study was to assess the phylogenetic position of this parasite using partial sequences of 28S rRNA gene. In the phylogenetic tree, A. curtus appeared as a sister taxon to the dactylogyrine genus Gobioecetes. The new molecular evidence supports the hypothesis about the non-monophyletic status of Ancyrocephalus sensu lato.

The present study describes two new species of monopisthocotylans parasitizing the gills of Cyphocharax modestus (Characiformes: Curimatidae) from two localities of the Upper Paraná River basin, state of São Paulo, Brazil. Urocleidoides saghirus n. sp. and Urocleidoides taquariensis n. sp. differ from other congeners mainly in the morphology of the accessory piece: comprising two subunits (one scythe-shaped subunit, and one adjacent piece with a narrow base broadening towards the upper end, which is axe-shaped) in Urocleidoides saghirus n. sp., and a straight rod with a bifurcated proximal portion, a distal portion ending in a point, and two curved handles arising from the medial portion and uniting close to the distal portion in Urocleidoides taquariensis n. sp. The phylogenetic analyses revealed Urocleidoides to be non-monophyletic, indicating the need for a taxonomic review. This study provides the first molecular sequences for Urocleidoides spp. parasitizing Curimatidae, including the newly described species. These findings revealed distinct clades and suggested possible host specificity, underscoring the importance of additional research to better understand the phylogenetic relationships within the genus.
