Neither the plate caption nor Buffon's description included a scientific name but in 1783 the Dutch naturalist Pieter Boddaert coined the binomial name Montacilla galeata in his catalogue of the Planches Enluminées. In the mid-twentieth century some authors placed the helmeted pygmy tyrant by itself in genus Colopteryx; that genus was soon merged into Lophotriccus. Several authors have suggested that genus Lophotriccus should be merged into genus Hemitriccus. Genus Lophotriccus had been introduced by the German ornithologist Hans von Berlepsch in 1883.
