In the Bahiagrass pasture, the number of oribatid species was smaller than in the chestnut orchard under eco-friendly agriculture and the grassy lawn in the park. Four of eleven species collected from the Bahiagrass pasture were also collected from the chestnut orchard and the grassy lawn. The remaining seven species were peculiar in the Bahiagrass pasture. A new species, Hermannia (Phyllhermannia) maruokaensis, was collected from the grassy lawn. Oribatid mites are subdivided taxonomically into Lower, Brachypylina and Poronata. In Japanese grassland and pasture, the number of Lower (primitive) species was abundant. On the other hand, the abundant species was the Brachypylina species in the forest and the Poronata species in the cultivated field.
