The genus contains two species: * Southern chestnut-tailed antbird (''Sciaphylax hemimelaena'') * Northern chestnut-tailed antbird (''Sciaphylax castanea'') These species were formerly included in the genus ''Myrmeciza''. A molecular phylogenetic study published in 2013 found that ''Myrmeciza'' was polyphyletic. In the resulting rearrangement to create monophyletic genera, the two chestnut-tailed antbirds was moved to a newly erected genus ''Sciaphylax''. The type species is the southern chestnut-tailed antbird. The name of the new genus combines the Ancient Greek words ''skia'' "shadow" and ''phylax'' "a watcher". ''Sciaphylax'' occur in non-overlapping regions. Species in this genus are known for their reddish to chestnut plumage, short tails, and sexually dimorphic features. They typically forage near the ground, often alone or in pairs, capturing insects through perch-gleaning and short leaps. Their ...
