Dysithamnus


Dysithamnus is a genus of insectivorous passerine birds in the antbird family, Thamnophilidae. Species in this genus are known as antvireos.

Taxonomy

The genus Dysithamnus was introduced by the German ornithologist Jean Cabanis in 1847. The name combines the Ancient Greek words duō "to plunge" and thamnos "bush". The type species was subsequently designated as the spot-breasted antvireo.
A molecular phylogenetic study published in 2020 found that the genus Dysithamnus was not monophyletic. The spot-crowned antvireo and the streak-crowned antvireo were sister to a clade containing the remaining species in the genus Dysithamnus and the antwrens in the genus Herpsilochmus.
The genus contains the following eight species:
