Dactylogyrids are flatworms of ecological and economic significance, parasitizing fish worldwide. In recent years, there has been a surge in the description of Neotropical dactylogyrids, particularly those infecting siluriform fishes. While these studies have contributed to the organization of some genera and refined species boundaries through integrative taxonomy, certain groups within the family, such as Demidospermus, remain taxonomically unstable. This study focuses on Demidospermus, aiming to reclassify species of uncertain status into appropriate genera and establish a morphological framework to support future evolutionary analyses and taxonomic revisions within the Demidospermus-like species group. Supported by morphological phylogenetic analysis, we propose the new genera Rhabdolachosus n. gen., Martorellius n. gen., Magnanchistrius n. gen., and Sicohencotyle n. gen., along with the resurrection of Omothecium Kritsky, Thatcher & Boeger, 1987, and Paramphocleithrium Suriano & Incorvaia, 1995. Additionally, two new species are described: Sicohencotyle antoniomaiai n. gen. n. sp. and Ameloblastella sakulocirra n. sp. Also, Demidospermus centromochi Mendoza-Franco & Scholz, 2009 is classified as sedis mutabilis, while D. annulus Marcotegui & Martorelli, 2011, D. brevicirrus Mendoza-Palmero et al., 2012, D. cornicinus Kritsky & Gutierrez, 1998, D. idolus Kritsky & Gutierrez, 1998, D. armostus Kritsky & Gutierrez, 1998, D. mortenthaleri Mendoza-Palmero et al., 2012, D. osteomystax Tavernari et al., 2010, D. tocantinensis Cohen et al., 2020, D. doncellae Morey et al., 2024, D. bifurcatus Justo, Martins & Cohen, 2024, D. juruaensis Justo, Martins & Cohen, 2024, and D. takemotoi Justo, Martins & Cohen, 2024 are considered incertae sedis. Lastly, Urocleidoides amazonensis Mizelle & Kritsky, 1969 remains classified as incertae sedis. Les Dactylogyridae sont des vers plats d'importance & eacute;cologique et & eacute;conomique, parasitant les poissons du monde entier. Ces derni & egrave;res ann & eacute;es, on a assist & eacute; & agrave; une forte augmentation de la description de Dactylogyridae n & eacute;otropicaux, en particulier ceux qui infectent les poissons siluriformes. Si ces & eacute;tudes ont contribu & eacute; & agrave; l'organisation de certains genres et & agrave; l'affinement des fronti & egrave;res entre esp & egrave;ces gr & acirc;ce & agrave; une taxonomie int & eacute;grative, certains groupes de la famille, comme Demidospermus, demeurent taxonomiquement instables. Cette & eacute;tude se concentre sur Demidospermus et vise & agrave; reclasser les esp & egrave;ces au statut incertain dans des genres appropri & eacute;s et & agrave; & eacute;tablir un cadre morphologique pour & eacute;tayer les futures analyses & eacute;volutives et r & eacute;visions taxonomiques au sein du groupe d'esp & egrave;ces apparent & eacute;es & agrave; Demidospermus. En nous appuyant sur une analyse phylog & eacute;n & eacute;tique morphologique, nous proposons les nouveaux genres Rhabdolachosus n. gen., Martorellius n. gen., Magnanchistrius n. gen. et Sicohencotyle n. gen., ainsi que la r & eacute;surrection d'Omothecium Kritsky, Thatcher & Boeger, 1987 et de Paramphocleithrium Suriano & Incorvaia, 1995. De plus, deux nouvelles esp & egrave;ces sont d & eacute;crites : Sicohencotyle antoniomaiai n. gen. n. sp. et Ameloblastella sakulocirra n. sp. Demidospermus centromochi Mendoza-Franco & Scholz, 2009 est class & eacute; comme sedis mutabilis, tandis que D. annulus Marcotegui & Martorelli, 2011, D. brevicirrus Mendoza-Palmero et al., 2012, D. cornicinus Kritsky & Gutierrez, 1998, D. idolus Kritsky & Gutierrez, 1998, D. armostus Kritsky & Gutierrez, 1998, D. mortenthaleri Mendoza-Palmero et al., 2012, D. osteomystax Tavernari et al., 2010, D. tocantinensis Cohen et al., 2020, D. doncellae Morey et al., 2024, D. bifurcatus Justo, Martins & Cohen, 2024, D. juruaensis Justo, Martins & Cohen, 2024 et D. takemotoi Justo, Martins & Cohen, 2024, sont consid & eacute;r & eacute;s comme incertae sedis. Urocleidoides amazonensis Mizelle & Kritsky, 1969 reste class & eacute; comme incertae sedis. (AU) | |
