As one of such biotopes, Sesshogawara of Kusatsu, Gumma Prefecture, was selected and an investigation was carried out to examine change of soil fauna, especially oribatid mites, in parallel with the change of vegetation. The result showed that the oribatid community of woodland became more and more simple toward the spouting point of the gas. The oribatid species found there contained two new species, Allomycobates lichenis and Ceratozetes, which are described in the last part of the paper.}, pages = {177--186}, title = {Zonation of Oribatid Mite Communities around Sesshogawara of Kusatsu, A Spouting Area of Sulfurous Acid Gas, With Description of Two New Species}, volume = {2}, year = {1976} }
