Stahlianthus rubromarginatus S. Q. Tong (Acta Phytotax. Sin. 33: 499. 1995) was described from a cultivated plant introduced to Mengla, S Yunnan from N Myanmar. It was transferred to Kaempferia by Searle (Telopea 8: 375. 1999), as K. rubromarginata (S. Q. Tong) R. J. Searle, but, according to Wu and Chen (Acta Phytotax. Sin. 34: 204. 1996), it is a synonym of K. parviflora Wallich ex Baker, which is distributed in India, Myanmar, and Thailand.
Six species: Cambodia, China, India, Laos, Myanmar, Sikkim, Thailand, Vietnam; one species in China.
