(Ramphastidae; Ϯ Gould's Toucanet S. gouldii) Gr. σεληνη selēnē  moon; δειρη deirē or δερα dera  neck, collar; "Genus SELENIDERA.   CHARACTERES GENERICI.  Rostrum brevius et crassius quam in genere Pteroglosso, nec non cauda brevior est ratione ad magnitudinem corporis habita; inter sexus color differt, mare caput pectusque nigra habente; his partibus fœmina castaneis; plumæ auriculares flavæ; lunulaque flava cervicem imum cingit. Ad hanc notam titula generica refert.  ...  The genus Aulacorhynchus having been very generally adopted, I take this opportunity of making a further subdivision of the family by separating from the true Pteroglossi (of which Ptero. araçari and Ptero. pluricinctus are typical examples,) the following species, viz. Pteroglossus Gouldii, Ptero. maculirostris, Ptero. Nattereri, Ptero. Reinwardsii, Ptero. Langsdorffii, and Ptero. Culik, under the generic name of Selenidera  ...  They are distinguished by yellow ear-coverts, and a lunar-shaped band of the same colour across the lower part of the neck, to which latter peculiarity our subgeneric title alludes." (Gould 1837); "Selenidera Gould, Icon. Av., pt. 1, 1837, pl. [7] and text. Type, by subsequent designation, S. Gouldii (Natt.) = Pteroglossus gouldii Natterer (G. R. Gray, List Gen. Bds., 1840, p. 50.)" (Peters 1948, VI, 79).
Synon. Piperivorus, Ramphastoides.
