Dot-backed Antbird
Hylophylax punctulatus
The dot-backed antbird is 10 to 11.5 cm (3.9 to 4.5 in) long and weighs 11 to 13 g (0.39 to 0.46 oz). Adult males have a dark rufous-brown crown, nape, and mantle with a white patch between their scapulars. Their back and rump are black with large white feather tips. Their flight feathers are dark brown with wide rufous-brown edges and their wing coverts black with wide white to pale buff tips. Their tail is black with white feather tips. Their face is mostly white; their throat and the lower sides of their neck are black. Voice: The male dot-backed antbird's song is "a series of doublets each about 0·5 seconds long of 2 somewhat similar sharp whistles, the first emphasizing an upslur and the second a downslur, sounding like "free beer", delivered at rate of c. 1 every 2 seconds, sometimes for minutes at a time, doublet often given singly". Its note has also been written as "whee-beéyur" and "wee-HEEew".

Spotted Antbird
Hylophylax naevioides
The spotted antbird is 10 to 12 cm (3.9 to 4.7 in) long and weighs 15 to 19.5 g (0.53 to 0.69 oz). The two subspecies have essentially the same plumage. Adult males have a gray forehead and a grayish brown to olive-brown crown and nape. Their back is chestnut with a white and chestnut patch between their scapulars; the white is usually not visible. Their uppertail coverts are dull cinnamon. Their wings are black with cinnamon-rufous tips on the coverts. Their tail is grayish brown with cinnamon tips on most of the feathers (pale brown to white on the outermost) and a black band above the tips. Voice: The spotted antbird's most common song is a variable number of repeated syllables each composed of a peeee whistle followed by a short ti note, giving a full sequence peeeeeti-peeeti-peeeti-peeeti-peeeti-peeeti-peeeti-peeeti of variable length. Both sexes sing, with the male's song longer than female's.
