Justification:
This species is endemic to Eswatini.  It is however quite widespread within the country, with an extent of occurrence (EOO) of 3915 km2 and an area of occupancy (AOO) of 176 km2. It appears to be tolerant of habitat degradation, and is therefore not considered to be threatened.  Based on this, it has been assessed as Least Concern.
