A study published in 2007 confirmed that the lined antshrike is a full species and sister to the chestnut-backed.

The lined antshrike is 16 to 17 cm (6.3 to 6.7 in) long and weighs 26 to 28 g (0.92 to 0.99 oz). Members of genus Thamnophilus are largish members of the antbird family; all have stout bills with a hook like those of true shrikes.
