Primulina titan Z.B. Xin, W.C. Chou & F. Wen, a new species from limestone areas in Guangxi, China is described and illustrated with photographs. It resembles P. hunanensis, but can be easily distinguished by a combination of morphological characteristics of leaf blades, petiole, bracts, corolla, filaments, anthers and pistil. We found only one population with approx. 800 mature individuals at the type locality. This species is provisionally assessed as vulnerable [VU D1] using IUCN criteria.
