Abstract
The oribatid species of the taxon Ptyctima were studied in eight habitat types (four forests, three bogs, and one shore). Altogether 19 species were found. The highest number of species (15) was found in marsh forests in southern Finland, and the lowest number (3) in eutrophic fens in northern Finland. Atropacarus striculus was the most common and abundant species in Finland. It was found in each habitat explored, especially abundant on shores, in marsh forests, and pine bogs. Phthiracarus longulus, P. boresetosus, and Steganacarus carinatus occurred in abundance in coniferous forests, especially in the southern and central parts of the country, whereas Rhysotritia ardua was found there only occasionally. Hoploderma pavidus favoured bog habitats in Finland. Protoribotritia oligotricha was new to Finland. It was found in low numbers in the north.
