Plain-throated Antwren

About the Plain-throated Antwren

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: I. h. suffusa (Zimmer, JT, 1932) I. h. hauxwelli (Sclater, PL, 1857) I. h. clarior (Zimmer, JT, 1932)

I. h. hellmayri (Snethlage, E, 1906) The Clements taxonomy and BirdLife International's Handbook of the Birds of the World do not separately recognize I. h. clarior but include it within the nominate subspecies I. h. hauxwelli.
