This species is considered Near Threatened as it is known from only a small range, and is apparently rare and patchily distributed. However, the range is not yet severely fragmented or restricted to few locations (Collar et al. 1992). For these reasons, the species is classified as Near Threatened.

|Range Description:||Formicarius rufifrons was formerly known only from the río Madre de Dios and its tributaries, Peru, but during the 1990s it was found on the upper rio Juruá in Acre, Brazil (Whittaker and Oren 1999), río Tahuamanu in Pando, Bolivia (L. Jammes in litt. 1999, T. S. Schulenberg in litt. 1999) and río Urubamba in Cuzco, Peru (H. Lloyd in litt. 1999, N. Gerhart in litt. 2000), greatly extending its known range. It is generally rare and localised within this range. |
