Distribution and Habitat: China (S. Yunnan, Guangxi), S Myanmar, Thailand, N Vietnam, elevation 400–1900 m. In tropical montane rainforests, damp cloud forests, tea plantations, on the edge of forests, and on roadsides.

Assessment of Conservation Status: LC, with a wide range of distribution and relatively stable populations in Northern Indo-Chinese floristic region by the definition of IUCN. However, it should be noted that the rubber-tea agriculture in tropical areas may pose a threat to the habitat of this species.
