The Rio Suno Antwren is a typical ‘gray’ antwren; males are overall grayish with a large black throat patch, concealed white interscapular patch, and white wing coverts spotting, while females are olive-brown to grayish above and on the crown, entirely cinnamon below, and possess much less obvious, pale cinnamon, tips to the wing coverts. Named for the river of the same name, the Rio Suno Antwren occurs, somewhat locally, through south-central Colombia to east-central Peru, and in southwest Amazonian Brazil. It seems to be always uncommon or rare, and inhabits the lower and mid strata of lowland and foothill forests, primarily in terra firme, but also, at least locally, in seasonally flooded areas. The species is frequently found within mixed-species flocks in the undergrowth, in common with many of its congenerics.
