Each sample of about 200 cm3 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 5mfrom 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. © Nakamura K. et al.

A new oribatid species of Eremellidae was described from litter at the bottom of a hollow Ilex oldhami Miq. tree in Kumamoto Prefecture, in southern Japan in a subtropical area. The new species has long lamellar ridges subpararelly connected by two translamellar ridges, rostral setae longer than lamellar setae, two pairs of adanal setae, and long solenidion ϕ1 about four times as long as the length of the tibia. A key to all species of the genus Eremella is provided. Another new species, Scheloribates yamaeensis n. sp. was described from a chestnut plantation in Kumamoto Prefecture. The new species has a plicate integument, diverged sacculi, immovable pteromorphae with inward curve, a dorsosejugal suture, four pairs of genital setae, minute notogastral setae, adanal setae ad3 inserted in a preanal position, Trägårdh’s organ, three claws of legs, and smooth fastigial setae of tarsus I. © 2015, Les Amis d'Acarologia.

Representatives of six oribatid mite species belonging to the cohort Brachypylina were collected from the upper wall and soil surface at the entrance of Kumaso cave in South Nippon (Japan). Of these, three were known species: Fissicepheus (Fissicepheus) takenouchiensis Fujikawa and Nishi, 2013, Scheloribates latipes C. L. Koch, 1841 and Peloribates (Peloribates) latus Fujikawa, 2006. One species of Humerobates (Humerobates) was described as a new species. Two other individuals did not match any described species and may represent two new species. However, as single individuals, we could not decide with certainty about their specific status. These individuals were respectively assigned to the genera Protoribates and Spatiodamaeus. Here, we provide only morphological descriptions of these single specimens. No typically cave-dwelling oribatid mites were found in the present investigation. © 2014, Nakamura K. et al. Source

Eleven oribatid species were collected from the Kumaya Cave of Iheya village in Central Ryukyu Arc, South Japan. The cave is a descending horizontal tunnel of a deep-sea abysmal quartziferous deposit formed in the Permian period of the Palaeozoic era and excavated by sea erosion. The floor of the cave was covered with sand, three to four meters deep. Fragments of psephite are found at the end of the cave. Each sample of about 200 cm3 was collected by hand from the following five marked points of the cave on 17 March 2010: A, Sand and a fragment of psephite; B, Sand and a fragment of psephite; C, Sand, a fragment of psephite, and litter of Ficus microcarpa; D, Litter and humus of F. microcarpa and Cassytha filiformis, and sand; E, Litter and humus of F. microcarpa and C. filiformis, and sand. All species belonged to Brachypylina: Oppiella (O.) nova from A; Mabulatrichus kumayaensis sp. nov., Protoribates kumayaensis sp. nov. and Zygoribatula iheyaensis sp. nov. from B; Tectocepheus kumayaensis sp. nov. from C; Tectocepheus iheyaensis sp. nov., Oribatula kumayaensis sp. nov., Protoribates hirokous sp. nov. and Haplozetes makii sp. nov. from D; Eupelops kumayaensis sp. nov. from E; Neoliodes iheyaensis sp. nov. from C, D and E. © 2009-2011 ACAROLOGIA.
