Zoosystema 39 (4): 501-598. https://doi.org/10.5252/z2017n4a5 ABSTRACT 313 nominal species of monogenean parasites of aquatic vertebrates occurring in Mexico are included in this checklist; in addition, records of 54 undetermined taxa are also listed. All the monogeneans registered are associated with 363 vertebrate host taxa, and distributed in 498 localities pertaining to 29 of the 32 states of the Mexican Republic. The checklist contains updated information on their hosts, habitat, and distributional records. We revise the species list according to current schemes of KEY WORDS classification for the group. The checklist also included the published records in the last 11 years, Platyhelminthes, Mexico, since the latest list was made in 2006. We also included taxon mentioned in thesis and informal distribution, literature. As a result of our review, numerous records presented in the list published in 2006 were Actinopterygii, modified since inaccuracies and incomplete data were identified. Even though the inventory of the Elasmobranchii, Anura, monogenean fauna occurring in Mexican vertebrates is far from complete, the data contained in our Testudines. checklist depict the actual knowledge about this group of flatworms in Mexico. RÉSUMÉ Liste annotée des Monogenea (Platyhelminthes) parasites des vertébrés aquatiques mexicains. Une liste annotée des 313 espèces nominales de parasites monogènes de vertébrés aquatiques du Mexique est présentée ; 54 taxons indéterminés sont également répertoriés. Tous les monogènes cités sont associés à 363 taxons de vertébrés hôtes, et sont originaires de 498 localités représentant 29 des 32 états de la République mexicaine ; des informations révisées sur les hôtes, l’habitat et les distribu- tions sont proposées. La liste des espèces a été revisée en fonction des patrons actuels de classification du groupe. La liste annotée comprend également les signalisations publiées au cours des 11 dernières MOTS CLÉ années, puisque la dernière liste datait de 2006. Nous avons également inclus les taxons mentionnés Platyhelminthes, Mexique, dans les thèses et la littérature grise.
