 Six taxa of Elettariopsis Baker (Zingiberaceae) were previously accounted for Thailand. In this paper, Elettariopsis wandokthong, a new species from Thailand, is described and illustrated. Also, the distribution of Emonophylla (Gagnep.) Loes. in Thailand is reported here for the first time with full description and illustration. Key to species currently enumerated for Thailand is also provided.

Distribution: This new species can only be found in the type location. However, it is widely cultivated in Thailand.

 Ecology: The new species grows under the shade of dried deciduous forest, at the altitude of 62-240 m.

 Vernacular names: Wan Dokthong (วานดอกทอง), Wan Maha Saneh (วานมหาเสนห),  彎斗松擬荳蔻 (Chinese new name).
