This small lorikeet lives in the mountains of New Guinea. It feeds on nectar, flowers, and fruit in the canopy and mid-storey, often in pairs or small flocks.
Adults of the nominate subspecies O. a. arfaki are mainly green, with a red forehead, rows of white streaks below the eyes, and an orange-red abdomen. Other subspecies differ in belly or tail color.
It usually lives in montane moss forest at about 2,000–3,750 m, sometimes descending to around 1,000 m. It feeds on nectar and flowers of epiphytes and on fruit in the canopy and mid-storey.
