The International Ornithological Congress and the Handbook of the Birds of the World consider the moustached brushfinch to be monotypic - i.e. having no subspecies. The eBird/Clements and Howard and Moore checklists include the Merida brushfinch - "A. albofrenatus meridaeas" - as a subspecies of the moustached brushfinch.
