Craniorrhinus [sic] waldeni
Sometimes placed in Rhyticeros or Aceros. Has been suggested to form a species-group with R. corrugatus and R. leucocephalus, with Rhyticeros cassidix also in this group. Often considered conspecific with R. leucocephalus, but differs in plumage, bare parts, and degree of sexual dimorphism in colour of facial skin. Monotypic.
C Philippines: Panay and Negros (almost extinct in latter); extinct on Guimaras#R.
