Etymology and history of research

Louis Pierre Vieillot described the hummingbird under the name Trochilus albicollis . The bellows for the first description came from Brazil and were made available to Vieillot by the Muséum national d'histoire naturelle and from the private collection of Guillaume Michel Jérôme Meiffren de Laugier, Baron of Chartrouse (1772–1843). When Ludwig Reichenbach published an extra booklet with the systematics of the hummingbirds in an addendum to the assembly of German ornithologists , he added this species to the new genus Leucochloris .

The word “Leucochloris” is of Greek origin and is made up of the words “leukós λευκός ” for “white” and “khlōros χλωρός ” for “green”. The specific epithet “albicollis” is a Latin combination of “albus” for “white” and “collis” for “neck”.
