As a part of an ongoing inventory of the helminth parasites of freshwater fishes in Mexico, 570 individual fish were collected between April 2008 and October 2011 in 26 localities along the Cuatro Ciénegas region in Coahuila State, northern Mexico. Seventeen species of hosts, mostly corresponding to Nearctic freshwater elements, were studied. A total of 8324 individual worms were collected during this survey, representing 25 species of helminths of which 9 were digeneans, 3 monogeneans, 1 cestode, 3 acanthocephalans, and 9 nematodes. Most of the records in this checklist represent new host or locality records. The information provided in this checklist may be helpful for our understanding of the biodiversity and historical biogeography of this host-parasite system, since in the Cuatro Ciénegas region occur a Nearctic freshwater fish fauna, along with Neotropical and endemic elements and from a biogeographical point of view, may represent a transitional area.
