Male and female Black-throated Antbirds differ in throat and belly color. The male has a black throat and breast and forages in dense undergrowth near wetlands and streams.
The male is olive-brown above with a black tail, gray head and underparts, white spots on the wing-coverts, and a black throat, breast, and central belly. The female has a white throat and rufous belly.
It uses dense undergrowth at forest and woodland edges, especially near swamps or streams, and eats insects and other arthropods.
