The hylocitrea (Hylocitrea bonensis), also known as the yellow-flanked whistler or olive-flanked whistler, is a species of bird that is endemic to montane forests on the Indonesian island of Sulawesi. [3] It is monotypic within the genus Hylocitrea, and has traditionally been considered a member of the family Pachycephalidae, but recent genetic evidence suggests it should be placed in a monotypic subfamily of the family Bombycillidae, [4] or even its own family, Hylocitreidae. [1] A 2019 study [5] found it to be a sister group to a clade containing the hypocolius (Hypocoliidae) and the extinct Hawaiian honeyeaters (Mohoidae), with the clade containing all three being a sister group to the silky-flycatchers (Ptiliogonatidae). The divergences forming these families occurred in the early Miocene, about 20-23 million years ago. [5] [6]
