Taxonomy edit
The genus Willisornis was erected by the Brazilian ornithologists Carlos Agne and José Fernando Pacheco in 2007. The genus is named after the American ornithologist Edwin O'Neill Willis.[2] The common scale-backed antbird had traditionally been included in the genus Hylophylax, but is now known to belong to a different clade. The name Dichropogon was used briefly instead, but this name is preoccupied by a genus of asilid flies (Dichropogon Bezzi, 1910).[2][3][4]
The two species are:[5]
- Common scale-backed antbird (Willisornis poecilonotus)
- Xingu scale-backed antbird (Willisornis vidua)
The two species were previously considered conspecific. They were split based on the differences in their vocalization.[6][7]
