Primulina pingguoensis H.S. Ma & B. Pan, a new species of Gesneriaceae from Guangxi Zhuang Autonomous Region, China, is illustrated and described here. The new species morphologically resembles Primulina carinata Y.G. Wei, F. Wen & H.Z. Lü, but it differs from the latter by leaf blade elliptic to broadly ovate, 6.5–9.5 × 4.5–6.5 cm (vs. broadly elliptic to ovate, 4.0–5.0 × 3.0–4.0 cm), leaf blade base slightly oblique, cuneate (vs. rounded), leaf blade carnose (vs. subcoriaceous), corolla pinkish purple to pink (vs.purple or purplish red), corolla tube tubular, ventrally carinate, (vs. narrowly funnelform, strongly carinate, forming a clear keel), staminodes 2 (vs. 3). etc. The conservation status of P. pingguoensis is considered as ‘Critically Endangered’ (CR) according to the IUCN red list categories and criteria.
