Based on morphological observations and comparisons, a new species of Primulina (Gesneriaceae), Primulina arcuata G.L.Xu & L.Ding, is described and illustrated. This new species resembles P. jiulianshanensis in leaf blade shape, but differs from the latter by corolla tube curved-tubular (vs. funnelform); calyx lobes oblong (vs. lanceolate); peduncle, pedicel, both surfaces of bracts, both surfaces of bracteoles and abaxial surface of calyx lobes covered with glandular-puberulent hairs (vs. with eglandular-puberulent hairs). A detailed description, photographs, distribution information and a provisional conservation status assessment are provided.

The detailed morphological comparison of P. arcuata and P. jiulianshanensis in Table 1.
