The squamate antbird is 14 to 15 cm (5.5 to 5.9 in) long and weighs 16.5 to 20 g (0.58 to 0.71 oz).

Their flight feathers are brownish with rufous edges and their wing coverts black with wide white tips. Their chin and throat are black. Their breast and side feathers are black with wide white edges. Voice: The squamate antbird's song is "a countable series of doublets...similar to that of M. loricatus but starts at higher frequency and descends substantially more in pitch". Its call is "a short rattle and short downslurred note" that also is similar to the white-bibbed antbird's.
