The Lesser Melampitta lives in New Guinea's montane forests. This account separates an early description of an adult male from one survey record in eastern Papua New Guinea.
Schlegel's early description says an adult male has velvety black feathers on the forehead, around the eyes, at the base of the bill, and on the chin; the remaining plumage is black with a slight blue sheen.
The Bishop Museum report describes the Lesser Melampitta as montane, fairly common above 2,100 m, and rarely recorded as low as about 1,450 m.
An extinction-risk assessment has not been added yet.
