We describe the isolation and characterization of ten polymorphic microsatellite loci in the Andean pupfish Orestias agassizii. The number of alleles per locus in 25 individuals was high, varying from 5 to 25. Observed and expected mean heterozygosities were 0.750 and 0.767, respectively. The ten loci conformed to the Hardy-Weinberg equilibrium, and we did not detect linkage disequilibrium between loci. Cross-species amplification in O. luteus was entirely successful, and polymorphism was detected in all loci. One locus (A116) showed significant departure from Hardy-Weinberg equilibrium due to homozygote excess. These microsatellites will be useful for assessing the genetic structure and historical demography of Andean pupfishes, which are subject to a global collapse of their stocks.
