Abstract
Cornukaempferia Mood & K. Larsen (Zingiberaceae) is revised. Seven species of Cornukaempferia have been recognized with their updated nomenclature including C. aurantiiflora Mood & K. Larsen, C. longipetiolata Mood & K. Larsen, C. larsenii P. Saensouk, C. chayanii Yupparach & Wongsuwan, C. kamolwaniae Picheans., Yupparach & Wongsuwan, C. argentifolia Boonma & Saensouk, and a new species, Cornukaempferia srisumoniae P. Saensouk, S. Saensouk & Boonma sp. nov. After comparison to all previously existing species in the genus, the morphological characteristics of a new species are the most similar to C. argentifolia, but different in certain morphological characteristics. This new species is described here along with its illustrations, photographs, ecology, etymology, and distribution are provided. Six species are endemic to Thailand, while one species, C. larsenii P. Saensouk is native to Thailand and Laos PDR. A revised key to 7 species and descriptions is also presented.

Cornukaempferia srisumoniae P. Saensouk, Saensouk & Boonma sp. nov
Cornukaempferia srisumoniaeis similar to C. argentifolia, but different in having sessile to subsessile petiole up to 0.7 cm long (vs. C. argentifolia has petiole 2.5-4.5 cm long); leaf sheath 4-5 cm long (vs. 7-8 cm long); lamina broadly ovate (vs. ovate), leaves upper surface green, sometimes with few silvery marking, midrib green (vs. upper silver without marking, midrib lighter silver, sometimes with reddish tinge along the midrib); leaves lower surface green (vs. red); bracts sparsely hairy (vs. glabrous); labellum broadly obovate, 4.2-4.3 X 4.0-4.2 cm, apex rounded (vs. obovate, 3.4-3.6 X 2.6-2.8 cm, apex emarginate, each lobe acute with incision 5-6 mm long); filament 6.9-7.3 mm long (vs. 3.8 mm long); anther 2.3-2.4 cm long (vs. 2.8-3.0 cm long).
Etymology: The specific epithet "srisumoniae" is named after Associate professor Dr. Srisumon Sitathani, plant morphology and biology Specialist, and the founder of the Department of Biology. Faculty of Science, Khon Kaen University, where the Khon Kaen University Herbarium (KKU) is located.
