This Amazonian Inezia occurs in waterside woodland and thickets. Its two currently recognized subspecies share two pale wingbars and pale tail tips, but differ in their underpart coloration.
The two currently recognized subspecies share two whitish wingbars and pale edges and tips on the tail feathers. Nominate subflava is yellow from throat through belly; obscura has an olive wash across the center of the breast, making its yellow throat stand out.
The study describes both subflava and obscura mainly in shrubby waterside vegetation beside forest-bordered rivers, streams, and lakes. Birds use lower and middle forest levels, usually alone or in pairs, and glean arthropods from mostly live foliage.
