Oribatid mites were investigated qualitatively at 27 stations along a ridge from the top of Mt. Arakawa-dake (3141m) to near the pond of Komadori and the mountain cottage of Nikenn-goya in the South Japanese Alps. General features of oribatid fauna on this mountain are : (1) A higher percentage in the species of Poronota at dwarfish vegetation, (2) A decrease in the species number of the family Oppidae and an increase in the species number of the family Ceratozetidae, (3) A lack of Rhysotritia ardua, which is one of the most common species in the other areas, (4) A lack of Maerkelotritia kishidai under dwarfish vegetation and montane forests and (5) The presence of Brachychthonius berlesei, Camisia biverrucata, Carabodes labyrinthicus, Cepheus kurosawai and Liacarus bacillatus which is rare in Japan. The species composition of oribatid communities is related to the structure and form of vegetation.
