    Conservation
    Conservation notes: Endemic to the Mfuwe area of the central Luangwa Valley, where it is rare. Owing to current threats, and as two of the three known populations lie outside any Protected Area, the species is considered Endangered 2a. If other populations are found it would become Vulnerable D2.
