It has a white eye-ring with a dark outer edge. The head and back are olive to grayish, the throat yellow, the chest gray-green, and the belly pale rufous.
It is recorded in forest and dense habitats on Sao Tome. A conservation study of the island's endemic birds also notes dry woodland patches within savanna as habitat used by the former feae form.
