ResumenIn the examination of 143 Salmo trutta f. fario and 226 S. gairdneri caught in rivers and fish farms in León, we found 2 new Myxobolus spp. in S. trutta f. fario. Myxobolus farionis n. sp. parasitizes only the brain and spinal cord, while Myxobolus ibericus n. sp. is present in a variety of organs but never in the nervous tissue. The myxosporidians are described and drawings and photomicrographs are presented. Data on the prevalence and intensity of the infections are also given. In the analysis of the population dynamics a bimodal seasonality was evidenced. We observed a decrease in the prevalence with the age of the host, but there was no influence of the host sex on the infections. The 2 Myxobolus spp. seem not to influence each other.
