[2][3][4] The Para gnatcatcher is 10 to 11 cm (3.9 to 4.3 in) long and weighs approximately 6 g (0.21 oz).

The male's head, back, and breast are mouse gray and the rest of its underparts white.

[5] The Para gnatcatcher is found only in Brazil, in a broad band south of the Amazon River from its mouth southwest almost to northern Bolivia.

It inhabits the borders and canopy of humid primary forest, mostly below 500 m (1,600 ft) elevation.

[5] The Para gnatcatcher's song is "repeated high...notes, evenly delivered" [1].
