The plain-throated antwren (Isleria hauxwelli) is a species of bird in subfamily Thamnophilinae of family Thamnophilidae, the "typical antbirds". It is found in Bolivia, Brazil, Colombia, Ecuador, and Peru. The plain-throated antwren was described by the English zoologist Philip Sclater in 1857 and given the binomial name Formicivora hauxwelli in honour of the collector of the type specimen, John Hauxwell. It was later moved to genus Myrmotherula and then to the current genus Isleria that was introduced in 2012. The plain-throated antwren shares genus Isleria with the rufous-bellied antwren (I. guttata) and the two form a superspecies.
The plain-throated antwren's further taxonomy is unsettled. The International Ornithological Committee assigns it these four subspecies: This article follows the four-subspecies model. Wikipedia →

GBIF citizen-science records
It is estimated from how often the Plain-throated Antwren is recorded against all the birds logged in Tambopata National Reserve (518 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.
