Two species of Oligonychus are redescribed: O. baipisongisMa & Yuan, 1976 and O. chamaecyparisaeMa & Yuan, 1976. Moreover, O. hainanensisMa, Yuan & Lin, 1979 is here recognized as a junior synonym of O. biharensis (Hirst, 1924), which is also redescribed here based on adult females, males and deutonymphs. The redescription of O. baipisongis is based on holotype and paratypes, the types of O. chamaecyparisae could not be located but the species is described from male and female material collected by En-Pei Ma in 1978 from Lanzhou City, Xi-An City and Xining City. The dorsal setae in O. baipisongis show remarkable sexual dimorphism. The difference between the aedeagi of O. chamaecyparisae and Oligonychus perditusPritchard & Baker, 1955 are discussed. All three species are diagnosed, illustrated with line drawings and photographs.
