Subspecies
Subspecies tumbezana recently treated as a separate species, presumably including inflava and maranonica, but definitive studies lacking. Described taxon ignobilis (from south-central Bolivia, north-western Argentina and Paraguay) indistinguishable from nominate in large series, and thus merged with latter.
The following 7 subspecies are recognised:
eremonoma Wetmore, 1953 - Pacific lowlands of Panama.
incomta (Cabanis & Heine, 1860) - Colombia (northern and Andes) and northern Ecuador east to Venezuela (south to Apure, northern Amazonas and northern Bolívar) and Trinidad (including Monos I).
tumbezana (Taczanowski, 1877) - Pacific lowlands of south-western Ecuador and north-western Peru (Tumbes, eastern Piura, north-eastern Lambayeque).
inflava Chapman, 1924 - Arid north-western Peru from central Piura and central Lambayeque south to northern Lima.
maranonica J. T. Zimmer, 1941 - Arid north-central Peru in Marañón Valley, western Amazonas, eastern Cajamarca and eastern La Libertad.
wagae (Taczanowski, 1884) - The Guianas, Amazonian Brazil, eastern Peru and northern Bolivia.
murina (Spix, 1825) - Central, eastern and southern Brazil (Maranhío, Ceará and Pernambuco south to Mato Grosso and Sío Paulo), central Bolivia (Cochabamba south to Tarija), Paraguay and north-western Argentina (south to La Rioja).
