Abstract
Rungia sinothailandica (Acanthaceae), a new species from Yunnan, China and Chiang Rai, Thailand is described and illustrated. A colour plate, line drawing and distribution map of R. sinothailandica are provided. Rungia sinothailandica is similar to R. pinpienensis H. S. Lo, but differs in the broadly ovate sterile bracts and obovate-elliptic fertile bracts, the crispate and tawny bracts margin, the 2-lobed upper lip of the corolla and puberulent capsule. It is also similar to R. burmanica (C. B. Clarke) B. Hansen, but is easily distinguished by pubescent stems and leaves, the cymbiform-oblong bracteoles and the 2-lobed upper lip of corolla.
