Subspecies
No subspecies.
Genus has sometimes been placed in Coerebidae or Parulidae or even, because of an apparent close relationship to Acanthidops, in Emberizidae. Molecular phylogenies indicate that it is most closely related to Xenodacnis and to Acanthidops, Haplospiza and Catamenia (the last three genera currently placed in Emberizidae), and that all clearly belong in present family. Members of this clade may also be closely related to the Oreomanes/Conirostrum clade. Forms a superspecies with Chestnut-bellied Flowerpiercer (Diglossa gloriosissima) and Moustached Flowerpiercer (Diglossa mystacalis), and all formerly considered conspecific. Molecular-genetic data indicate that Chestnut-bellied Flowerpiercer (Diglossa gloriosissima) and Moustached Flowerpiercer (Diglossa mystacalis) are more closely related to each other than either is to present species.
