In June of 2005 and in May of 2006,the writer has collected some paper bags of mosses and dry barks from Huangshan（alt.1200-1500m）of Anhui Province and Qufu City（Konglin）of Shandong Province.During 2006,some paper bags of mosses and powdery remnant of wood were collected by Ms.WEI Yin-Xin of Institute of Hydrobiology,Chinese Academy of Sciences and Dr.WANG Quan-Xi of Shanghai Normal University from Sanya City of Hainan Province,Zalantun City and Genhe City of Inner Mongolia Autonomous Region and Wudalianchi City and Yichun City of Heilongjiang Province.Some paper bags of mosses,lichens and punks were collected by a graduate student Mr.Chen Feng from Milin County（29°13＇N;94°13＇E;alt.2997m）and Damxung County（30°27＇N;91°10＇E;alt.4060m）of Tibet Autonomous Region.Our knowledge of Tardigrada from these areas was rather meager.Using precipitation method,the writer have gotten more tardigrade specimens from these mosses,powdery remnant of wood,lichens and punks,including one new species and four newly recorded species for China.Simple descriptions of these species are given below.Class Eutardigrada Maroas, 1927 Order Apochela Schuster et al., 1980 Family Milnesiidae Ramazzotti, 1962 Genus Milnesium Doyere, 1840 Milnesium reductum Tumanov, 2006 were found in Huangshan of Anhui Province, Zalanum City of Inner Mongolia Autonomous Region, Wudalianchi City of Heilongjiang Province, Milin County of Tibet Autonomous Region and Sanya City of Hainan Province （Figs.1-3）. Body length 301.5-532.4 μm, maximum width 133.1-213.4 μm. Head with a pair of large eyes. Prknary branch and secondary branch are separated completedly. Secondary branch of inner claw with basal spur and the secondary branch of outer claw without basal spur.Order Parachela Schuster, 1980 Family Mzcrobiotidae Thulin, 1928 Gemts Macrobiotus Schdtze, 1834 Macr0b/0tu are0/a/us J. Murr. , 1907 were found in Wudalienchi City and Yichun City of Heilon^iang Province and Genhe City of Inner Mongolia Autonomous Region （Figs.4-7）. Body length 350.2-701.8 μm, maximum width 193.6-249.3 μm. Head without eye. Pharyngal ball with apophyses and three macroplacoids of rod shap, usually the third is longer and the second shorter, distances of macroplacoids expanding. Double daws with medium size and smooth lunulae. Conical projections of egg taper to points. Macrbiotu arguei Pilato ＆ Sperlinga, 1975 were found in Huangshan of Anhui Province, Wudalianchi City and Yichun City of Heilongjiang Province, Quill City （ Konglin ） of Shandong Province （ Figs. 8-11 ）. Body length 266.2- 489.0 μm, maximum width 95.62-133.2 μm. Head with small eyes. Pharyngal ball with apophyses, three round macroplacoids and a rather large microplacoid. Double claw present Y fork, with accessory points and lunulae. Egg with conical projections. Hypsibiidae Pilato, 1969 Diphascon Plate,1889 Diphascom（Adropion）pundatum （Iharos, 1962） were found in Huangshan of Anhui Province （Figs.12-14）. Body length 298.4 μm, maximum width 96.8μm, only one specimen. Head without eye. Buccal and pharyngal tube narrow and long, pharyngal ball is very elongated oval and containing two rod macroplacoids, the second equal to three muptiples length of the first, without microplacoid. Two double daws have different size, primary branches strong bent in a hook at the distal end. Lsolrypsibius Thulim,1928 Isohypsibius Damcaungensis. nov. were found in Damxtmg County of Tibet Autonomous Region （Eigs.15-18）. Body length 324.3-399.3μm, maximum width 101.6-145.2μm. Head with round eyes, rectangttlar or round sculptures of different size on the dorsal cuticle. Buccal tube narrow and short, pharyngal ball with apophyses and three macroplacoids and without microplacoid. The third length equal to the first two touched together. Two double claws have different size and shapes, outer claw with pointed base and strip lanulae, inner claw present V fork. All branches strongly bent in a hook at the distal end and with accessory points. So far as I know about 120 species of this genus have been described in the world. Damshune species differ from all known similar species in outer claws and inner claws. Therefore I consider them new to science. All the specimens are deposited in the Institute of Hydrobiology, Chinese Academy of Sciences, Wuhan. Etymology. Isohypsibius damxungensis sp. nov. is named in a souvenir for discovery place of qabet Autonomous Region, Ghina.
