Uniquely possesses all-white beard, apart from a few tiny green droplet-shaped spots on chin and throat (3); blackish crown sides (ns[1]); darkish brown underparts with relatively little pale scaling (1); no white in tail except white shaft streaks on all but central pair (3); longer crest than other taxa (effect size vs cyanolaemus 4.23, vs guerinii 3.086; score 2); and longer wings than other taxa (effect size vs next longest cyanolaemus 1.39; score 1)#R. Monotypic.
