Six helminth species were recorded during the helminthological examination of 35 specimens of the goodeid Xenotaenia resolanae from Arroyo Durazno, Jalisco, Mexico, a tributary of the Cuzalapa River. Helminth species identified included: 4 species of digeneans, i.e., Posthodiplostomum minimum (metacercariae), Clinostomum companatum (metacercariae), Dendrorchis sp. (adult), and Margotrema guillerminae (adult); and 2 species of nematodes, i.e., Spiroxys sp. (larvae) and Rhabdochona ahuehuellensis (adult). A very low number of individual larvae were found. The observed species richness, individual parasite abundance, and diversity were low at both component community and infracommunity levels. The values of similarity between infracommunities were relatively high because of the predominance of the digenean M. guillerminae, the species that reached the higher values of both prevalence and abundance. High water flow of the collecting site is suggested as the main factor determining the depauperate helminth assemblage in this fish species.
