The black-faced antbird is 12 to 13.5 cm (4.7 to 5.3 in) long and weighs 16 to 22 g (0.56 to 0.78 oz). Adult males of the nominate subspecies M. m. myotherinus have a dark bluish gray crown, nape, and upperparts with a small white patch between their scapulars. Their wings and tail are slightly darker gray with white tips on the wing coverts. Their face is mostly black with a pale supercilium. Their throat is black and the rest of their underparts pale gray with slightly darker sides, flanks, and crissum. Adult females have a dark grayish olive-brown crown, nape, and upperparts. Voice: The song of the nominate black-faced antbird is "a countable series...of evenly spaced, somewhat unclear (frequency-modulated) notes, pitch and intensity rising initially, falling terminally, notes become longer throughout" that has been written as "zree-zree-zree-zrut-zrut".
