Tassonomia

The rufous-winged woodpecker was originally described as Chloronerpes simplex. Since its inclusion in Piculus it has at times been considered conspecific with the stripe-cheeked woodpecker (P. callopterus), the white-throated woodpecker (P. leucolaemus), and the Lita woodpecker (P. litae); the four may form a superspecies. The rufous-winged woodpecker is monotypic but at times part of the Honduran population has been proposed as a subspecies.
