Taxonomy and systematics
The genus Monarcha was introduced by naturalists Nicholas Vigors and Thomas Horsfield in 1827 with the black-faced monarch (Monarcha melanopsis) as the type species. The genus formerly included many more species. Based on the results of a molecular phylogenetic study published in 2005  nineteen species were moved to the resurrected genus Symposiachrus and three to Carterornis.
