Trachylaemus is a genus of birds in the African barbet family (Lybiidae). The genus is closely related to the genus Trachyphonus .
The genus Trachylaemus was introduced in 1891 by the German ornithologist Anton Reichenow. [1] The name combines Ancient Greek τραχυς/trakhus meaning "rough" or "shaggy" with λαιμος/laimos meaning "throat". [2] Reichenow subsequently designated the type species as Trachyphonus purpuratus Verreaux, J & Verreaux, É, 1851, the eastern yellow-billed barbet. [3] [4]
