ABSTRACT
Agapetes lihengiana Bin Yang & Y.H.Tan (Ericaceae) is described and illustrated as a new species endemic to
Yunnan, China. It is morphologically similar to A. epacridea Airy Shaw and A. trianguli Airy Shaw, but clearly differs in having
flowers with shorter pedicel and white corolla with 5 vertical pink stripes, and conspicuous secondary veins on the abaxial surface
of leaf blades. A detailed description, colour plates, and notes on the new species are provided.

Diagnosis: Agapetes lihengiana is morphologically similar to A. epacridea and A. trianguli in having spirally alternate leaves no more than 1.5cm long and 1cm wide, and branchlets densely covered with spreading setae, but can be clearly distinguished from the former by its leaf blade with an acute or apiculate apex (vs. leaf blade apex with a 1–1.5 mm long pungent mucro), secondary veins conspicuous (vs. obscure), and shorter pedicel (ca.1 mm vs. 4–5 mm); and from the latter by its white corolla with five vertical pink stripes (vs. blood red), shorter pedicel (ca.1 mm vs. 3–4 mm), and shorter anther (5 mm vs.7.5 mm) (Table 1).
Etymology: The specific epithet is named in honor of Prof. Heng Li of Kunming Institute of Botany, who has made great contributions to our knowledge of the flora of Gaoligong Mountains in China.
