Several former subspecies of the Emerald Toucanet are now classified as separate species, or were re-assigned to other species:
1. Wagler's Toucanet,
2. Blue-throated Toucanet,
3. Violet-throated Toucanet,
4. White-throated Toucanet, and
5. Black-throated Toucanet.

The Santa Marta Toucanet and the Grey-throated Toucanet were both formerly considered as a separate species (Aulacorhynchus lautus and Aulacorhynchus griseigularis respectively) until lumped as a subspecies of the White-throated Toucanet in 2016.
