Thehylocitrea (Hylocitrea bonensis), also known as theyellow-flanked whistler orolive-flanked whistler, is a species ofbird that isendemic to montane forests on theIndonesian island ofSulawesi.[3] It ismonotypic within the genusHylocitrea, and has traditionally been considered a member of the familyPachycephalidae, but recentgenetic evidence suggests it should be placed in a monotypic subfamily of the familyBombycillidae,[4] or even its own family,Hylocitreidae.[1] A 2019 study[5] found it to be asister group to a clade containing thehypocolius (Hypocoliidae) and the extinctHawaiian honeyeaters (Mohoidae), with the clade containing all three being a sister group to thesilky-flycatchers (Ptiliogonatidae). The divergences forming these families occurred in the earlyMiocene, about 20-23 million years ago.[5][6]
