This typical “Scytalopus” tapaculo is found only in Colombia’s western Andes. Plumage is gray with a brown tinge to the rump and faint, rusty barring on the lower underparts. Similar to Nariño Tapaculo, Spillmann’s Tapaculo, and Choco Tapaculo, and is best identified by its distinctive voice. Song is a long, pulsating series of frog-like calls that gradually increases in volume and pitch. Inhabits understory of cloud forest and is normally quite hard to see.
