Primulina pingguoensis H. S. Ma & B. Pan, a new species of Primulina Hance, Gesneriaceae from Guangxi Zhuang Autonomous Region, China, is illustrated and described here. The new species morphologically resembles P. carinata Y. G. Wei, F. Wen & H. Z. Lü, but it differs from the latter by lobes narrowly lanceolate-linear, length-width ratio more than 2(rounded-ovate, length-width ratio less than 1.5), 8-10 purple stripes from corolla throat to the bottom of corolla tube, the same color with corolla, without honey guides(vs. brown stripes, different color with corolla, 2 yellow honey guides inside), leaf blade elliptic to broadly ovate, (6.5-9.5) cm × (4.5-6.5)cm [(vs. broadly elliptic to ovate, (4.0-5.0) cm × (3.0-4.0)cm], leaf blade base slightly cuneate(vs. rounded), corolla tube tubular, ventrally carinate, (vs. narrowly funnelform, strongly carinate, forming a clear keel), etc. The conservation status of P. pingguoensis is considered as ‘Critically Endangered'(CR)according to the IUCN red list categories and criteria.
