Often separated with A. tickelli in genus Ptilolaemus; the two are often treated as conspecific, but present species differs by male’s white vs orange-brown lower face and throat (3); male’s slightly broader, more truncate casque (1); female’s whitish vs black bill (3); and female’s greyer, less tan underparts (1). Birds from Thailand and Indochina sometimes recognized as race indochinensis, but appear inseparable from other populations. Monotypic.
