Subspecies
Paroaria gularis (Sibley and Monroe 1990, 1993; Stotz et al. 1996) has been split into Red-capped Cardinal (Paroaria gularis) and Masked Cardinal (Paroaria nigrogenis) following SACC (2011).
Recent molecular-genetic research indicates that genus belongs in the tanager family (Thraupidae), forming a clade with, among others, Cissopis and Schistochlamys. Curiously, members of latter two genera are similar in some plumage features and in bill shape to some members of present genus. May form a superspecies with Masked Cardinal (Paroaria nigrogenis), Crimson-fronted Cardinal (Paroaria baeri) and Yellow-billed Cardinal (Paroaria capitata), and all have sometimes been placed in a separate genus, Coccopsis. Appears to be closest to Yellow-billed Cardinal (Paroaria capitata). Previously considered conspecific with Masked Cardinal (Paroaria nigrogenis), but appears not to be genetically close enough to it to warrant such treatment.
Has been proposed that subspecies cervicalis be afforded full species rank, but more work needed to determine what degree of reproductive isolation, if any, exists. Specimens from southern part of range of nominate have reduced black around eyes, suggesting that variation possibly clinal.
The following 2 subspecies are recognised:
gularis (Linnaeus, 1766) - Eastern Colombia (southern Meta south to Amazonas), eastern Ecuador and eastern Peru, southern Venezuela (western Amazonas and southern Bolívar), the Guianas, and Amazonian lowlands of north-central Brazil (including R Negro and mouth of R Amazon).
cervicalis Sclater, PL, 1862 - North-eastern Bolivia (Pando, eastern La Paz, Beni, eastern Cochabamba and Santa Cruz) and adjacent Brazil (western Mato Grosso).
