Cabanis

, 1849,

#R, Cumaka, coast of Guyana

.

Molecular study covering “capped” (“capuchino”) Sporophila found that they formed two clades, a N clade largely N of R Amazon containing present species and S. minuta, and a S clade consisting of S. hypoxantha, S. hypochroma, S. ruficollis, S. palustris, S. cinnamomea and S. melanogaster, to which group S. bouvreuil is sister#R. Proposed taxon S. hypochroma rothi (based on single specimen from near Abary, in NE Guyana) probably a hybrid between present species and S. minuta. Monotypic.

Distribution:

The Guianas, and E Colombia (from Guainía and Meta) and S Venezuela (extreme SW Amazonas) S, E of Andes, to Ecuador, Peru and N & W Bolivia (Pando, La Paz, Beni and Cochabamba), and Amazonian Brazil (S to NW Mato Grosso and N Pará, also NE Roraima and Amapá).
