The white-browed antbird was described in 1844 as Pithys leucophrys. Other subspecies and the geographical redistribution of these four have been suggested but as of 2024 not accepted. Authors have suggested that some of the subspecies might better be treated as full species.
The white-browed antbird is 12 to 13.5 cm (4.7 to 5.3 in) long and weighs 18 to 22 g (0.63 to 0.78 oz).

GBIF citizen-science records
It is estimated from how often the White-browed Antbird is recorded against all the birds logged in Madidi National Park (23 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
