Ten microsatellite loci were isolated from a species of the Neotropical electric eel, Eigenmannia, a genus of freshwater fish characterized by small populations and low vagility. Nine microsatellites were polymorphic, the number of alleles ranging from seven to 27, and values of observed heterozygosity ranging from 0.327 to 0.741. These loci were developed for population genetic studies of Eigenmannia sp. 2, however, cross-amplification carried out with other species of this genus as well as other Gymnotiformes genera indicate that these molecular markers are also potentially useful for population-level studies in closely related species.
