The Mentawai malkoha (Phaenicophaeus oeneicaudus) is a species of cuckoo in the family Cuculidae.

The Mentawai malkoha was formally described in 1855 by the French naturalists Jules and Édouard Verreaux under the current binomial name Phaenicophaeus oeneicaudus.

[2] The Italian zoologist Tommaso Salvadori realised that this was an error and the specimen must instead have come from the Mentawai Islands which lie in the Indian Ocean approximately 150 km (93 mi) off the western coast of Sumatra.

[3][4] The genus name Phaenicophaeus is from Ancient Greek φοινικοφαης (phoinikophaēs) meaning "of crimson appearance" or "red-gleaming".

It was promoted to species status based on the morphological differences.
