Based on examination of protologues and herbarium material, combined with field observations, we suggest that Zeuxine bidupensis Averyanov should be considered a heterotypic synonym of Z. agyokuana Fukuyama. Thus, the known distribution of Z. agyokuana includes China, India, Japan, Thailand and Vietnam. A neotype is designated for Z. agyokuana, since all original material underlying Fukuyama's description seems to be lost. An improved morphological description, based on all available herbarium material from the entire geographic range of the species, is provided together with illustrations.
