Not only does this bird have a plain throat, the male, seen here in photos 1 and 3, also has two white wing-bars on its black wings, white tips to the tertials seen on either side of the back, and a white tip to its short tail. The female (photo 2) is olive-brown above with buff replacing the male's white on the wing-bars and below it is bright cinnamon-rufous with a paler throat.

Female Plain-throated Antwren, Carajás, Pará, Brazil, October 2005 - click for larger image This female is particularly dark below because it belongs to the sub-species I. h. hellmayri. The males are of the nominate sub-species.

Unlike most Myrmotherula antwrens, the Plain-throated stays fairly close to the ground and is usually seen clinging sideways to vertical saplings.
