The African terrestrial barbets are the bird genus ''Trachyphonus'' in the African barbet family (Lybiidae), which was formerly included in the Capitonidae and sometimes in the Ramphastidae. These birds are more terrestrial than the other African barbets and differ in some other respects too; they are thus separated in a monotypic subfamily Trachyphoninae. ==Species in taxonomic sequence== * Yellow-billed barbet, ''Trachyphonus purpuratus'' * Crested barbet, ''Trachyphonus vaillantii'' * Yellow-breasted barbet, ''Trachyphonus margaritatus'' * Red-and-yellow barbet, ''Trachyphonus erythrocephalus'' * D'Arnaud's barbet, ''Trachyphonus darnaudii'' * * Usambiro barbet, ''Trachyphonus (darnaudii) usambiro'' The Early to Middle Miocene genus ''Capitonides'' from Europe as well as "CMC 152", a distal carpometacarpus from the Middle Miocene locality of Grive-Saint-Alban (France) have been placed into this genus,〔Mlíkovský, Jirí (2002): ''Cenozoic Birds of the World, Part 1: Europe''. Ninox Press, Prague. (PDF fulltext )〕 but this move is not widely accepted. In the case of "CMC 152", this may be more warranted as this fragment differs from ''Capitonides'' and is more similar to extant (presumably Old World) barbets.〔Ballmann, Peter (1969): Les Oiseaux miocènes de la Grive-Saint-Alban (Isère) (Miocene birds of Grive-Saint-Alban (Isère) ).
