| Type location: |
Zambia, Mpulungu |
| Notes: | This taxon was described from only the type collection on Kumbula Island across from Mpulungu Harbour; habitat degradation of the escarpment woodland canopy posses a high risk to the understorey flora as population pressure increases in the Mpulungu area. |
