Golden-bellied Starfrontlet is split into three species, based on plumage differences, and because genetic evidence indicates that a polytypic Golden-bellied Starfrontlet is paraphyletic with respect to Blue-throated Starfrontlet Coeligena helianthea (Palacios et al. 2019). Therefore the monotypic group Golden-bellied Starfrontlet (Perija) Coeligena bonapartei consita is recognized as Perija Starfrontlet Coeligena consita; the monotypic group Golden-bellied Starfrontlet (Golden-bellied) Coeligena bonapartei bonapartei is recognized as Golden-bellied Starfrontlet Coeligena bonapartei; and the monotypic group Golden-bellied Starfrontlet (Golden-tailed) Coeligena bonapartei eos is recognized as Merida Starfrontlet Coeligena eos.
