However, molecular studies have consistently found mangabeys to be diphyletic, with the six terrestrial mangabey species forming a clade with drills and mandrills (and with macaques too in some studies), and the two arboreal mangabeys forming a clade with baboons and geladas.

Skeletal and dental morphology supports diphyletic origin of baboons and mandrills.

If correct, this diphyletic take on mangabey affinities would mean that geladas, baboons, drills and mandrills do not form a clade of ‘dog-faced cercopithecids’ as conventionally thought.

Bush warblers are particularly newsworthy right now (to my mind at any rate) given that the just-published oscine supertree of Jønsson & Fjeldså (2006) found Cettia to be diphyletic, with C. cetti grouping with the tesias* and Urosphena (the stubtails) while the Japanese bush warbler C. diphone grouped with the Broad-billed flycatcher-warbler Tickellia hodgsoni and Orthotomus (the tailorbirds).
