Oribatid Mites (Acari, Oribatida) From Tohoku (Northeast Japan), Collected After A Tidal Wave In 2011

Each sample of about 200 cm(3) was collected on June 27th 2011 by hand from the following three marked points after a large tidal wave (Tsunami) struck on March 11th 2011: Two specimens belonging to Masthermannia and Eupelops were collected from a sample A (about 188 m from sea); five specimens of four species belonging to Nothrus and Tectocepheus from sample B (about 5 m from sample A) were found; twenty-five specimens of Trhypochthonius, Scheloribates and Trichogalumna from sample C (about 20 m from sample B) were collected. One oribatid species of the Masthermannia genus from sample A was found to be identical to an undescribed species from Kumamoto Prefecture, which was studied together with the specimen from sample A.
