Scarce antwren found mainly in lowland rainforest, but ranges up into mountains in the northern part of its range. Male has mostly gray underparts, black-and-white spots on throat, and whitish or tan spots and bars on wings; back color varies geographically from brown to chestnut. Female is brown, lacks throat markings, and has less distinct wing markings. Dull brown tail distinguishes it from Rufous-tailed Stipplethroat. Male’s checkered throat and female’s lack of throat markings help separate it from Ornate Stipplethroat. Almost always encountered in mixed-species understory flocks with antshrikes and other antwrens. Song is a high-pitched, descending trill; also often gives a dry rattle.
