Resumen:
In total, 9 endohelminth species were found to parasitize 7 fish species (2 cyprinids, 4 goodeids, and 1 poeciilid) from La Mintzita Reservoir, Michoacan, in central Mexico; 5 were larvae, including 3 allogenic species (Clinostomum complanatum, Tylodelphys sp., Posthodiplostomum minimum) and 2 autogenic species (Serpinema trispinosum, Spiroxys sp.). Four were enteric autogenic adults, i.e., Margotrema bravoae, Bothriocephalus acheilognathi, Proteocephalus longicollis, and Rhabdochona lichtenfelsi. The metacercariae of P. minimum. reached the highest levels of prevalence and mean abundance among host species. Our results confirm the depauperate nature of the helminth communities of freshwater fishes from central Mexico. On the basis of this data set, we estimated the total endohelminth species richness for each component community by using 7 nonparametric estimators whose performance was evaluated with the unsealed measures of bias, precision, and accuracy. We found that Chaol and Boots
