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.
