Other common names: Bamboo Flatbill
Taxonomy: Tyrannula megacephala Swainson, 1835, São Paulo, Brazil.
Present genus formerly believed to be allied to flatbills (Tolmomyias and Rhynchocyclus), but apparently belongs instead with Myiarchus and relatives, based on cranial, syringeal and nesting characters; molecular data still lacking. Present species formerly placed in genus Tolmomyias. Four subspecies recognized.
