A new species of Begonia section Coelocentrum, B. guangdongensis W.H. Tu, B.M. Wang & Y.L. Li from Guangdong Province, China, is described and illustrated here. Morphologically, the new species is most similar to B. biflora T. C. Ku and B. longistyla Y. M. Shui & W. H. Chen, but differs from B. biflora by its rugose leaves and glabrous capsules and from B. longistyla by its glabrous stipules without ciliate margin, densely hirsute-pilose leaves and obtuse apex of bracts. Additionally, it is also somewhat similar to B. chongzuoensis Yan Liu, S. M. Ku & C.-I Peng, but there are significant distinctions in their stipules, leaves and bracts. The conservation status of B. guangdongensis is assessed as Critically Endangered (CR), according to the IUCN Red List Categories and Criteria.
