This order is represented by the Family Nyctibiidae (potoos). 


Timetree of Nyctibiiformes based on White et al. (2017), with the distribution of each taxon being indicated by the colour-code used throughout this website (see Distribution colour code). The divergence time between Nyctibius and Phyllaemulor has not been determined yet. The depicted timing is just a rough guess given here.
