Subspecies
Genus formerly placed in its own separate family, Vireolaniidae. Alternatively, is sometimes placed in a subfamily, Vireolaniinae. Present species has been placed by some authorities in separate genus, Smaragdolanius, along with Green Shrike-Vireo (Vireolanius pulchellus) and Slaty-capped Shrike-vireo (Vireolanius leucotis). Possibly forms a superspecies with Green Shrike-Vireo (Vireolanius pulchellus) and often treated as conspecific, being very similar in plumage and vocalizations. No known intergrades between the two where ranges approach each other in eastern Panama. Poorly known subspecies mutabilis (described from specimen of a female) considered by some to be inadequately differentiated to warrant recognition.
The following 2 subspecies are recognised:
mutabilis Baird, 1866 - Eastern Panama (eastern Darién, Cana) and north-western Colombia (Córdoba, Antioquia, northern Chocó).
eximius Baird, 1866 - Northern Colombia (south-western Guajira and Cesar south to Santander and Boyacá) and north-western Venezuela (Sierra de Perijá, western Zulia and southern Táchira).
