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 Yellow-browed Shrike-vireo (Vireolanius eximius) and Slaty-capped Shrike-vireo (Vireolanius leucotis). Possibly forms a superspecies with Yellow-browed Shrike-vireo (Vireolanius eximius) 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.
Proposed subspecies dearborni (described from central-southern Guatemala) requires substantiation, and is currently synonymized with nominate.
The following 4 subspecies are recognised:
ramosi Phillips, AR, 1991 - South-eastern Mexico (southern Veracruz east to north-central Chiapas and Quintana Roo, south to eastern Oaxaca).
pulchellus Sclater & Salvin, 1859 - South-eastern Mexico (south-eastern Campeche, south-western Quintana Roo), Guatemala (except central highlands), Belize and Caribbean slopes of Honduras and northern Nicaragua.
verticalis Ridgway, 1885 - Nicaragua (on Caribbean slopes), Costa Rica and western Panama (eastern Veraguas).
viridiceps Ridgway, 1903 - Central Panama (east to Panamá province).
