The white-rumped robin (Peneothello bimaculata) is a species of bird in the family Petroicidae. It is found in New Guinea. Its natural habitats are subtropical or tropical moist lowland forests and subtropical or tropical moist montane forests.
Described by Italian naturalist Tommaso Salvadori in 1874, the white-rumped robin is a member of the Australasian robin family Petroicidae, or Eopsaltridae. Sibley and Ahlquist's DNA-DNA hybridisation studies placed this group in a Corvida parvorder comprising many tropical and Australian passerines including pardalotes, fairy-wrens and honeyeaters as well as crows. However, subsequent molecular research (and current consensus) places the robins as a very early offshoot of the Passerida (or "advanced" songbirds) within the songbird lineage.
Within the species, two subspecies are recognised: the nominate, which is found on the southern side of the main mountain range along New Guinea, and the subspecies vicarius of the Huon Peninsula and Adelbert Range.
Measuring 13 to 14 cm (5.1 to 5.5 in), the white-rumped robin has black plumage with a white rump and upper tail coverts. It has white patches on its sides of its breast. The abdomen is white in the nominate subspecies and black with some white in the subspecies vicarius. The female closely resembles the male, but its black feathers have brown tinges. The bill and feet are black, and the eyes are dark brown.
The white-rumped robin is found in the highlands of New Guinea from altitudes of 300 to 1,700 m (980 to 5,580 ft). Within the rainforest it is found in pairs in the understory or on the ground. It is insectivorous.
