Listed as Vulnerable because its Extent of Occurrence is less than 20,000 km2, its distribution is severely fragmented, and there is continuing decline in the extent and quality of its forest habitat in the Eastern Arc Mountains of Tanzania.
This species occurs in the Usambara (East and West) and Nguu Mountains in Tanzania. Its altitudinal range is not fully known, but it is a species of medium to high altitudes. Records from the coastal plain of Tanzania require confirmation.
The main threat is habitat loss due to agricultural encroachment, logging, and expanding human settlements. Its habitat in the East Usambara Mountains has recently come under serious threat as a result of the activities of illegal gold miners.
