RANGE DESCRIPTION
This species ranges from northern South Asia, into southern China and northern parts of Southeast Asia. In South Asia, this species is presently known from Bhutan (Ganghlakha), India (Arunachal Pradesh, Mizoram, Uttar Pradesh and West Bengal) and Nepal (Eastern Nepal) (Molur et al. 2002). In China it is present in southern Xixang and eastern Yunnan. In Southeast Asia, there are records from Myanmar, northern Thailand and Viet Nam. It has been recorded from 308 to 2,710 m asl.

DESCRIPTION
In South Asia, although it is widespread, it is not a common species (Molur et al. 2002). In China, the species is little known, but is believed to be most common in lower montane forests. It is uncommonly encountered in Southeast Asia.

Threats in detail
THREATS
In South Asia, this species is threatened by habitat loss largely through commercial harvest of bamboo (Molur et al. 2002). There appear to be no major threats to the species in Southeast Asia. In China, the threats to this species are unclear although it may be threatened by ongoing habitat degradation.
