36 species of the two families were found in the Świętokrzyski Region; they included 29 species of the family Muscidae (Muscinae) and 7 species of the family Scathophagidae, which account for 85% and 10% respectively, of their numbers recorded from Poland. Most of them are widely distributed saprophages and polyphages. 19 species within these families are new to the region studied and Dasyphora albofasciata and Cordilura socialis are new to the fauna of Poland. 32 species are synanthropes. The highest number of 23 species was recorded in the mixed coniferous forest. The Muscinae and Scathophagidae fauna of the Świętokrzyski Region was compared to that of Muscinae and Scathophagidae of other regions in Poland. An analysis of the species composition and dominance structure was carried out in six habitats selected in the Bieszczady Mts., the Pieniny Mts., the Świętokrzyski Region and the Mazovian Lowland.
