Pterygiella luzhijiangensis Huan C. Wang, is described and illustrated as a new species endemic to Yunnan, southwest China. It occurs in thickets of the Luzhijiang hot-dry valley at elevations of 1000–1300 m. This new species is closely related to P. duclouxii Franch., but clearly differs from the latter by its procumbent stems, much branched at the base, 7-20 cm long, the leaves 1-2.2 cm long, 0.1–0.2 (0.25) cm wide, the corolla 2-2.2cm long, obviously longer than the calyx, with the lower lip of the corolla much longer than the upper one.
