A new species of Orangescirulinae, Orangescirula lii Chen & Jin sp. nov., is described and illustrated. It is characterized by having 2 claw-like setae, no solenidion and adorsal setae on palpal tibiotarsus, having 5 pairs of hysterogastral setae, 1 bsl and 5 sts on tibia III, 1 asl and 3 bsl on tarsus I. A key to adult females of Orangescirula of the world is provided. [ABSTRACT FROM AUTHOR]

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. [ABSTRACT FROM AUTHOR]

Two new species of genus Cunaxa, namely, C. papilla Chen & Jin sp. nov. and C. striata Chen & Jin sp. nov. are described and illustrated. C. papilla Chen & Jin sp. nov. was collected in Ruyuan Yao Autonomous County, Shaoguan City, Guangdong province, China. It's similar to C. magoebaensis Den Heyer, 1979, but differs from it by the long finger-like apophysis on the palp telofemur, propodosomal shield with fine papillae and c1, c2, d1, e1, f1 and h1 situated on small platelets. C. striata Chen & Jin sp. nov. was collected in Qingchuan County, Sichuan province and Zhaoqing City, Guangdong province, China. It's similar to C. yaylensisSergeyenko, 2009, but differs from it by the propodosomal shield with broken striae, c1 longer than or equal to f1 and h1 in length, f1 extending beyond the base of h1 and two pairs of hysterogastral setae (hgs1–hgs2). A key to adult females of Cunaxa species of the China is provided. [ABSTRACT FROM AUTHOR]
