Differs from T. nicefori by its lack of faint barring on back to tail-coverts (1) and from T. rufalbus by its blurry brownish vs sharp blackish streaks on cheeks (1); and from both by its paler upperparts (1); much finer barring on wings and tail (2); smaller size (notably shorter wing; allow 2); and minor vocal differences, i.e. wider range of notes in single phrase (1) and less use of repetitions/trilled series (1)—claims for greater vocal distinctiveness#R not confirmed here and questioned elsewhere#R. Species first discovered in Feb 2006. Monotypic.
