The genus Xenornis is monotypic, and of uncertain affinities. Chapman (1924) considered it to be "a member of the thamnophiline group", although he did not define the boundaries of this group. Whitney and Rosenberg (1993) noted similarities in foraging behavior (sallying for prey) to both Thamnomanes sp. and to Megastictus margaritatus (Pearly Antshrike). Also, like Megastictus (but unlike Thamnomanes), Xenornis often perches on slender vertical branches, and changes perches frequently. On the other hand, the call of Xenornis is similar to a frequent call of Thamnomanes caesius (Cinereous Antshrike) and Thamnomanes schistogynus (Bluish-slate Antshrike).
