The Southern Chestnut-tailed Antbird (*Sciaphylax hemimelaena*) is a secretive, medium-sized passerine, measuring approximately 13-14 cm (5.1-5.5 inches) in length and weighing around 16-19 grams.

This antbird primarily inhabits the understory of humid lowland terra firme forests and second growth, favoring areas with dense vegetation. It is typically found at elevations ranging from near sea level up to approximately 900-1000 meters (3,000-3,300 feet).
Primarily insectivorous, consuming a variety of arthropods including ants, beetles, spiders, and orthopterans. They forage by gleaning prey from vegetation and the forest floor.

They employ a 'skulking' foraging strategy, gleaning insects and other arthropods from low-lying foliage, dead leaves, and branches. While not obligate ant-followers, t...
