This gnatcatcher is documented in the canopy of western Amazonian forest. Its original description reported specimens and recordings from a small number of sites in Amazonas, Brazil.
The described adult males have dark slate upperparts, throat, and chest, a thin broken white eye ring, and white on the outer tail feathers. No female specimen was available.
It forages alone or in pairs in the canopy of upland terra firme forest on sandy soils and is reported with mixed-species canopy flocks. It gleans prey from leaves and twigs.
An extinction-risk assessment has not been added yet.
