Red Myzomelas occur on New Guinea, Yapen, and New Britain. On New Guinea, they visit flowering trees in the mountains, and males are conspicuously red.
Males on New Guinea are glossy red over much of the body, with the back darker than the area above the tail.
In New Guinea's mountains, it searches the canopy for nectar and gleans small insects from leaves where flowers are absent. Sago palms and flowering coconuts are among the reported feeding sites.
Adults of the nominate New Guinea subspecies have black bills and rufous-brown eyes.
An extinction-risk assessment has not been added yet.
