Naming
The western subspecies was described in 2019 as a distinct species based on its unique song. The western yellow-spotted barbet has a song described by Nigel James Collar and Peter Boesman as "a series of 7–10 accelerating notes similar to a song of hairy-breasted barbet ", while the eastern yellow-spotted barbet has a song described by Collar and Boesman as a "characteristic purring, unique among [African] barbets". These song differences led to the description of "B. dowsetti" as a distinct species. In 2023, the International Ornithological Congress recognized "dowsetti" as a distinct taxon, but tentatively kept it as a subspecies of "duchailllui" due to other studies finding significant divergences elsewhere within the species' range, indicating that "B. duchaillui" as a whole may represent a species complex.Two subspecies are known:
⤷ "B. d. duchailllui" - eastern and central Africa, west to Nigeria
⤷ "B. d. dowsetti" Boesman & Collar, 2019 - Sierra Leone to Togo
