Willisornis is a genus of insectivorous passerine birds in the antbird family, Thamnophilidae. These small, strongly sexually dichromatic birds are native to the Guianas and Amazon rainforest in South America, and often follow army ants.
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]
The two species were previously considered conspecific. They were split based on the differences in their vocalization. [6] [7]

The fire-eyes, Pyriglena, are a genus of birds in the antbird family Thamnophilidae.The genus contains 5 species, all found in South America. The fire-eyes are 16–18 cm in length, weigh 25-36 g and have characteristic red eyes that give them their name. They have sexually dimorphic plumage, with the females possessing brown to buff coloured bodies with black tails, and the males being black with small patches of white on the back or wings. The fire-eyes eat a variety of insects, and will regularly follow army ants in order to catch prey flushed by them. Two of the fire-eyes are widespread and safe, but one species, the fringe-backed fire-eye, is threatened with extinction.
