Following a 1988 publication, taxonomic systems moved albifacies and several other species from Todirostrum to genus Poecilotriccus. By the early twenty-first century genus Poecilotriccus had species called both "tody-tyrant" and "tody-flycatcher" so taxonomic systems began renaming the "tyrants" to "flycatcher". The white-cheeked tody-flycatcher is monotypic. == Description == The white-cheeked tody-flycatcher is about 9.5 cm (3.7 in) long and weighs about 8 g (0.28 oz).
