The white-throated toucanet was originally described in the genus "Pteroglossus". Although not accepted yet by all authorities, the white-throated toucanet was split from the emerald toucanet to form a separate species. 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. Alternative names for  the white-throated toucanet include the Andean toucanet, greyish-throated toucanet, north Andean toucanet, northern Andean toucanet and southern emerald toucanet. Subspecies.
