The taxon is represented by ~23 species in one family, the Musophagidae, confined to Africa.

Genus-level phylogeny of extant Musophagidae according to Perktas et al. (2020), with the distribution of each family being indicated by the colour-code used throughout this website (Distribution code). The "timetree" is largely imaginary and based on the limited data provided by Stiller et al. (2024): Tauraco + (Corythaeola + Corythaixoides). [Chronotaxonomics would unite Crinifer and Corythaeola in one subfamily.]
