The White-gaped Honeyeater is recorded in northern Australia. A 1977 Northern Territory account says it is common in dense vegetation and mangroves in the far north, while farther south it is confined to waterside vegetation.
This small grey-brown honeyeater has a bright white patch behind the bill. Its wings have an olive wash, its underparts are pale grey, and its upperparts are darker grey-brown; the black bill curves downward.
The Northern Territory account records it in dense vegetation and mangroves in the far north, but says it is less numerous farther south and confined there to waterside vegetation. A separate regional guide lists nectar, insects, and fruit as foods.
