Johannes's tody-tyrant, or Joao's tody-tyrant, (Hemitriccus iohannis) is a species of bird in the family Tyrannidae, the tyrant flycatchers. It is found in Bolivia, Brazil, Colombia, Ecuador, and Peru. == Taxonomy and systematics == Johannes's tody-tyrant has a complicated taxonomic history. It was originally described in 1907 as Euscarthmus iohannis.
