Abstract: A new species of Gesneriaceae, Chiritopsis lingchuanensis Yan Liu & Y. G. Wei, which was found to grow in a karst cave in Lingchuan County, Guangxi, China, is described and illustrated. The new species is similar to C. bipinnatifida W. T. Wang in having cymes lax-flowered, the corolla white, distinctly 2-lipped, the posterior lip three times shorter than the anterior one, and the staminodes 3, but differs by having leaves undivided and stamens pubescent. The new species is also similar to C. repanda W. T. Wang in the leaf shape, but differs in its corolla indistinctly 2-lipped, the posterior lip subequal to the anterior one, stamens glabrous, and the staminodes 2.
