A new orchid species, Hemipilia avisoides, is described from Songpan County, Sichuan Province, China. Morphologically, it is most similar to H. occidensichuanensis (≡ Ponerorchis limprichtii), but H. avisoides can be easily distinguished by its pendulous lateral lip lobes, the oblong middle lip lobe that is smaller than lateral lobes, the dorsal sepal that is concave at each side of central vein below middle, floral bracts that are always shorter than ovary, the leaf that is appressed to substrate and is adaxially green with white and parallel veins, and the solitary sheath at the base of stem. Floral morphology of H. avisoides is also presented by utilizing in vivo micro-CT scanning and 3D visualization.
