Taxonomic note
Alethe diademata and A. castanea (Sibley and Monroe 1990, 1993) were previously lumped into A. diademata following Dowsett and Forbes-Watson (1993), however Upper Guinea diademata is now accepted as a species separate from Lower Guinea A. castanea on account of:  large white spots in tail (3);  olive brown vs rufous-chestnut mantle to rump (3); black vs dark brown tail (2); juvenile with more clearly marked white chin and belly (u [1 or 2]).
