Abstract
Agapetes rhuichengiana Bin Yang & Y.H.Tan (Ericaceae) is described and illustrated as a new species from Southeast Xizang, China. It is morphologically similar to A. huangiana Bin Yang, Y.H.Tan & Y.H.Tong, but differs in having flowers densely covered with white to light yellowish brown villi, shorter stamens, and fruits that are smaller, depressed subglobose, and villous and verrucose.

Agapetes rhuichengiana Bin Yang & Y.H.Tan, sp. nov.
Diagnosis: Agapetes rhuichengiana is morphologically similar to A. huangiana in having spirally alternate small, ovate leaves and branchlets, densely covered with spreading setae. A. rhuichengiana, however, can be clearly distinguished from A. huangiana by its sparsely puberulent corolla with dense white to light yellowish brown villi along the ridges (vs. densely white puberulent), shorter stamens (7.0–7.5 mm vs. 10.0– 10.5 mm), depressed subglobose (vs. globose) berry, ca. 8 mm (vs. 12–13 mm) in diam. in vivo, villous and verrucose (vs. densely white puberulent) (Table 1, Fig. S1).
Etymology: The specific epithet is named in honor of Prof. Rhui-Cheng Fang from the Kunming Institute of Botany, who made significant contributions to the flora of Ericaceae in China.
Chinese name: 瑞征树萝卜(Rui Zheng Shu Luo Bo).
