Lichenostomus
Lichenostomus is a genus of honeyeaters endemic to Australia.
The genus formerly contained twenty species but it was split after a molecular phylogenetic analysis published in 2011 showed that the genus was polyphyletic. Former members were moved to the six new genera: Nesoptilotis, Bolemoreus, Caligavis, Stomiopera, Gavicalis and Ptilotula.
The genus contains two species:
| Image | Scientific name | Common Name | Distribution |
| Lichenostomus melanops | Yellow-tufted honeyeater | east and southeast Australia | |
| Lichenostomus cratitius | Purple-gaped honeyeater | southwest and south-central Australia |
The name Lichenostomus was introduced by the German ornithologist Jean Cabanis in 1851. The word is derived from the Greek leikhēn meaning lichen or callous and stoma meaning mouth.
