was described as a subspecies of from specimens that were collected in 1956 in the region in and around Fizi, in present-day Democratic Republic of the Congo. We recently discovered in transitional and montane forest near the type locality and the southeastern Itombwe Plateau, respectively. A phylogenetic analysis (16S mitochondrial sequence data) of these samples and other species recovered as sister to with strong support, and rejected a close relationship between and both topotypic from Cameroon and from Kenya. Herein, we provide a detailed description of the morphometrics, colour pattern, male advertisement call and natural history of this poorly known species. At least one literature record of from Tanzania has notable differences from our data, and requires further study to ascertain its taxonomic status.
