Subspecies
Until recently, often placed in monotypic genus Polyplancta, but morphological and behavioural parallels, supported by genetic analysis, suggest that species belongs in Heliodoxa. Probably closely related to Black-throated Brilliant (Heliodoxa schreibersii). In past, occasionally placed in Clytolaema. Despite fairly extensive range, species shows only slight degree of variation.
