The northern chestnut-tailed antbird (Sciaphylax castanea) is a species of bird in the family Thamnophilidae. It is found in the Amazon Rainforest in northeastern Peru and far eastern Ecuador.

The northern chestnut-tailed antbird was originally described by the American ornithologist John Zimmer in 1932 as a subspecies of the southern chestnut-tailed antbird with the trinomial name Myrmeciza hemimelaena castanea.[2] A molecular phylogenetic study published in 2013 found that the genus Myrmeciza, as then defined, was polyphyletic.[3] In the resulting rearrangement to create monophyletic genera the northern chestnut-tailed antbird and the southern chestnut-tailed antbird were moved to a newly erected genus Sciaphylax.[4]


Sciaphylax castanea is 11–12 cm in length and weighs 16–17 grams.[5] It is similar to its congener Sciaphylax hemimelaena, but differentiated by their vocalisations. The tail is short. The male has a dark gray head and neck and reddish-brown upper parts, the wing coverts are blackish with white or yellowish-brown tips, the tail is rufous-brown; the throat and breast are black with gray and brown on the sides and flanks, the midribs are white. The female is similar to the male, but paler; the throat and breast are chestnut to rufous orange, the belly is white tinged with yellowish brown.[6]
