This study deals with three genera, seven species and four subspecies of the tribe Neohiraseini Hennemann & Conle, 2008 from Hainan Province, China. The genera Pseudocententa Chen, He & Li, 2002 and Qiongphasma Chen, He & Li, 2002 are revised and redescribed, including descriptions of four new species, P. liui spec. nov., Q. bispinosus spec. nov., Q. huishanensis spec. nov. and Q. wuzhishanense spec. nov., and three new subspecies, Q. bispinosus bispinosus subspec. nov., Q. b. minor subspec. nov. and Q. jianfengense obtusicristata subspec. nov. First descriptions are given for the male and egg of Pseudocentema bispinatum Chen & He, 2002 and for the female of Q. jianfengense jianfengense Chen & He, 2002 sen. str. A new genus, Neoqiongphasma gen. nov., is established for N. diaoluoshanensis spec. nov., distinguished from Pseudocentema by its spinose thorax and from Qiongphasma by its unarmed head.
