The unstreaked tit-tyrant shares genus Uromyias with the agile tit-tyrant (U. agilis) and the two form a superspecies. The unstreaked tit-tyrant has three subspecies, the nominate U. a. agraphia (Chapman, 1919), U. a. plengei (Schulenberg & Graham, 1981), and U. a. squamiger (O'Neill & Parker, TA, 1976). == Description == The unstreaked tit-tyrant is 12 to 13 cm (4.7 to 5.1 in) long and weighs about 10 g (0.35 oz).
