Taxonomic and distributional notes: The putative holotype of Hildebrandtia angolensis 
Nieden, 1908 is not marked as such in the ZMB catalogue, but it appears to be the only candidate 
specimen in the Berlin collection that is consistent with the type locality of “Loanda.” See also 
taxonomic account for Hildebrandtia ornata.
