The fauna of terrestrial Parasitengona was studied in a human-transformed habitat, located on the Odra River shore in Wrocław agglomeration, and compared with that observed in natural habitats. The anthropogenic influence did not markedly affect the species diversity due to the presence of microhabitats which created favourable conditions for the mites. Altogether 13 species, representing four families and constituting almost nine percent of the Polish fauna of Parasitengona terrestria, were found within the studied area of ca. 200 m2. Species composition, compared with that observed in undisturbed habitat, differed with respect to nine taxa. Data on biology and ecology of the examined taxa are provided. The results of laboratory experiments allow for synonymization of Hauptmannia brevicollis Oudemans, 1910 with Abrolophus norvegicus (Thor, 1900) and Hauptmannia pseudolongicollis Haitlinger, 1987 with Abrolophus quisquiliarus (Hermann, 1804).
