The curl-crested araçari was first described by Johann Georg Wagler in 1832 and was formerly placed in the monotypic genus, “Beauharnaisius”, rather than its current genus, “Pteroglossus”.

The curl-crested araçari was first described by Johann Georg Wagler in 1832.

Because of its relatively long tail and curly crest, the curl-crested araçari was formerly placed in the monotypic genus or subgenus Beauharnaisius, but genetic data indicates that this species is embedded within Pteroglossus, being sister-species to the Eastern red-necked araçari (Pteroglossus bitorquatus).
