Parasenecio sylviaensis S.W. Chung & T.C. Hsu (Asteraceae, Senecioneae), a new species from Taiwan, is described and illustrated. The new species has long been misidentified as P. hwangshanicus (Y. Ling) C. I Peng & S. W. Chung but is indeed distinct in having wingless petioles and capitula with 4-7 florets. It is also similar to P. petasitoides (H. Lév.) Y. L. Chen but distinguishable in having much smaller habit, paniculate synflorescence and shorter puberulent phyllaries. P. sylviaensis is endemic to Taiwan where it is restricted to the high-altitude Abies forests around the Xueshan region.
