The Marquesan monarch was originally described in the genus Monarcha.

The Marquesan monarch was once fairly common and widespread in the Marquesas inhabiting islands such as Ua Pou, Nuku Hiva, Hiva Oa, Tahuata, and Mohotani but is now restricted to Mohotani.^[5] An ornithological study on Mohotani in 2000 estimated that there are approximately 80-125 (formerly 200-350 pairs in 1975) left on the small island.

The Marquesan monarch is mainly an insectivorous bird found in forest valleys at a variety of different altitudes. The species mainly prefers lowland forest but, most of that habitat was destroyed. Adults prefer areas of dense vegetation while immature birds often prefer shrubby vegetation in dry areas.

The rare Marquesan monarch faces further endangerment from hunting by feral cats and the polynesian rat, both of which are non-native introduced species to the island of Mohotani. All the Marquesas Islands have been damaged heavily by intense grazing and fire, and much of the original dry forest has been reduced to grassland while upland forest is now reduced to small forest patches.
