Description |
Geographic Range [top]
Range Description: The species has been reliably recorded from hilly areas in Kachin State in northern Myanmar, mainly in the last century, but also in 2005 by J. Murata (Bastmeijer 2006), and reported in tropical evergreen forests north of Myitkyina (Rhind 2010). There are reports of this species from Lao PDR and speculation that it could occur in southern China, but these appear to be unfounded (Merrill 1941, Kress et al. 2003, Bastmeijer 2006, Tanaka et al. 2007).
