(Lybiidae; Ϯ Acacia Pied Barbet N. leucomelas) Gr. νοτος notos south; genus Pogonias Illiger, 1811, barbet. "Tricholaema leucomelan (Boddaert), of which Tricholaema affine Shelley is a synonym, the characters being those of immature birds, as pointed out by Neumann, Journ. für Orn. 1910, p. 197, should be removed from the genus, the type species of which (T. hirsutum) is much larger and has the bristles of the face extremely long, reaching to the end of the bill; I therefore place it in a new genus under the name of Notopogonius, type Bucco leucomelas Boddaert." (A. Roberts 1922).
