Previously, the genus was attributed to the family of forest singers ( Parulidae ). An analysis of mitochondrial DNA in 2002 showed that the genus does not belong to this family, and according to a study published in 2013, the closest relative of the genus is the nettle thrush ( Zeledonia ). Although the authors of the study recommended separating Teretistris and Zeledonia into separate monotypic families, both genera are assigned to the Zeledoniidae family in the 3rd edition of the Complete List of Howard and Moore Birds of the World. In 2017, the genus Teretistris was nevertheless allocated to the Teretistridae family.
