Etymology and history of research
Eugène Simon described the species under its current name Chætocercus berlepschi . He mentions Ecuador as the location of the type specimen. The generic name is made up of the Greek words "khaitē χαιτη " for "long, flying hair" and "kerkos κερκος " for "tail". The specific epithet »berlepschi« is dedicated to Count Hans Hermann Carl Ludwig von Berlepsch (1850–1915). So wrote Simon:
"Je dédie cette espèce au savant ornithologiste le comte H. von Berlepsch, qui a bien voulu m'aider des ses conseils. »
The local population calls this species of hummingbird Atamari .
