Cheilolejeunea intertexta (Lindenb.) Steph. is newly reported for China except Taiwan, and Cheilolejeunea trifaria (Reinw. et al.) Mizut. is documented for the first time for mainland China except Hainan and Taiwan. The detailed description and illustration of Cheilolejeunea osumiensis as well as the key to the five Cheilolejeunea species of Hong Kong are also presented.
