Dinesen et al., 1994,
Ndundulu Mountains, in Udzungwa Mountains, Tanzania.
Originally thought to be an aberrant species of forest francolin, but extensive taxonomic study indicates that present species is probably most closely related to the Asiatic genus Arborophila; significant similarities include pattern of underwing-coverts, scaling on rear part of tarsus, several general plumage features, tree-roosting habit and whistling calls. Taxon obscurata, originally described as a subspecies, has been elevated to species level#R#R on basis of smaller size, speckled face, no white necklace, non-ochraceous undertail-coverts, less distinctly barred secondaries, scaly-patterned wing-coverts, narrower rectrices and a 0.5% biomolecular divergence; but none of these characters appears to be truly significant. Later analysis of DNA data, however, suggests lack of recent gene flow between the two populations, which are separated geographically by only 100 km, and they differ in details of ornaments and colours of face and tail (which are likely to function as visual signals)#R. Further investigation needed. Two subspecies recognized.
