The Usambara Hyliota has a blue-black back and a white wing patch. A 1999 survey recorded it singly or in pairs, usually in the canopy of mature trees at forest edges in Tanzania’s East Usambaras. That paper used the older subspecies name Hyliota (australis) usambarae and said its status as a separate species was unresolved at the time.
It has a blue-black back, a white patch on the wings, and a pale breast washed with yellow-orange. Pairs seen in the 1995 survey described in the 1999 paper appeared to show little difference in plumage between the sexes.
In the 1995 survey, birds were found singly or in pairs, usually in the canopy of mature trees at forest edges. They were recorded in a mixed-species flock once.
