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 .

Taxonomic and distributional notes:

Hildebrandtia ornatissima was described by

Bocage (1879c) based on a single specimen from the type locality “Bihé.” Later, Nieden

(1908) described Hildebrandtia angolensis from “Loanda” but this nomen was preoccupied by Rana angolensis Bocage, 1866 .

Boulenger (1919) proposed Rana miotympa- MAP 77. Distribution of Hildebrandtia ornata in Angola. num as a replacement name for Hildebrandtia angolensis , and Schmidt and Inger (1959) later recognized this as a junior synonym of Rana ornata ornatissima (Schmidt and Inger 1959) . Perret (1976a) removed H. ornatissima from synonymy with Hildebrandtia ornata ( Peters, 1878) , though this has not been accepted by all subsequent authors and whether these represent one or two species remains unclear. Channing (2001) referred all specimens of Hildebrandtia from southern and central Africa, including from Angola, to H. ornata . In contrast, Poynton and Haacke (1993), Ruas (1996), and Frétey et al. (2011) recognized both H. ornata and H. ornatissima in Angola. The delimitation of these two species requires further review.
