Five species of skin mites from Psorergatidae family have been found in four rodent species (Apodemus flavicollis, A. sylvaticus, Mus musculus, Myodes glareolus) coming from northern part of Poland. Three species (Psorergates microti, P. musculinus, P. simplex) appeared to be new ones for the fauna of Poland. Moreover A. sylvaticus and M. glareolus are a new hosts for P. apodemi, P. muricola, P. microti and P. musculinus from Poland. All developmental stages with immature stages predominance were found within particular species. The mites were found in skin fragments from different body areas, however they preferred head skin. The paper presents the list of species observed so far in Poland taking into consideration their hosts--currently the Psorergatidae fauna in Poland includes 10 species noted in eleven mammals species among rodents, bats and insectivores.
