Hoya tengchongensis, a new species of Apocynaceae, subfamily Asclepiadoideae from Yunnan, China, is described and illustrated. The new species is morphologically similar to Hoya serpens in creeping habit, bearing small and suborbicular leaves, and corolla tomentose adaxially. However, H. tengchongensis differs from H. serpens greatly in corolla size (ca. 7 mm vs. ca. 12 mm in diam) and corona morphology (corona lobes slightly ascending vs. erect).
