Penelope superciliaris

state of Pará, Brazil

.

May be closely related to P. marail. Has hybridized in captivity with P. purpurascens, P. pileata and Pipile cujubi. Described race cyanosparius (from headwaters of R Maués, in E Amazonas, in Brazil) apparently based on captive specimens, and further study needed; race alagoensis, described at same time by same author (but from NE Brazil)#R, has since been observed in the field and found to be distinctive#R#R. Proposed races ochromitra (from near Parnaguá, in S Piauí) and argyomitra (NW of Forte, in NE Goiás) are synonymized with jacupemba, and pseudonyma (from R Canhuma, near R Madeira, in Amazonas) with nominate. Four subspecies recognized.
