Taxonomy:

Penelope albipennis

Taczanowski

, 1878,

near Tumbes, Peru; type from Santa Lucía

.

Closely related to P. jacquacu, P. purpurascens, P. perspicax and P. obscura; probably closest to P. purpurascens or P. jacquacu. Validity as a species questioned in the past, with suggestions that it had been described from a partially albinistic specimen of P. ortoni or P. purpurascens, or that it constituted a morph or variant of one of these species; specific status now warranted#R. Monotypic.

Distribution:

Extreme NW Peru: recent records only from Piura, Lambayeque and Cajamarca; historically, occurred also in Tumbes, where some populations may persist. Original range supposed to extend N to near border with Ecuador, and S to R Chicama, in La Libertad. May also be present in large swampy area bordering Gulf of Guayaquil, in SW Ecuador.
