Records of 18 species of the families Micropezidae (1 species), Lonchaeidae (1 species), Lauxaniidae (1 species), Chamaemyiidae (6 species), Agromyzidae (6 species) and Chloropidae (3 species) from glacial sand deposits in the Czech Silesia (NE Czech Republic) are presented and their association with sandy habitats is discussed. All of them are recorded from the Czech Silesia for the first time, 4 are new additions to the fauna of Moravia and 9 for the whole Czech Republic. None of the recorded species is psammobiont but five of them are classified as psammophilous, viz. Micropeza lateralis Meigen, 1826 (Micropezidae), Calliopum geniculatum (Fabricius, 1805) (Lauxaniidae), Cerodontha (Xenophytomyza) leptophallus L. Papp, 2016, Ophiomyia disordens Pakalniškis, 1998 (both Agromyzidae), Aphanotrigonum parahastatum Dely-Draskovits, 1981 (Chloropidae), and Leucopis celsa Tanasijtshuk, 1979 as probably psammophilous. A new easternmost record of M. lateralis (from S. Poland: Godów) is presented and the association of this species and C. geniculatum with growths of Cytisus scoparius is confirmed. Leucopis monticola Tanasijtshuk, 1961, L. celsa and A. parahastatum are recorded from northernmost known localities. These species, and also C. (X.) leptophallus seem to be thermophilous and/or xerophilous and can be considered southern elements in the Silesian fauna of Diptera.
