| Popis: | WILLISORNIS VIDUA VIDUA (HELLMAYR, 1905) Taxonomy Genetic lineages with plumage characteristics discussed below can be assigned to W. v. vidua (type locality: Igarapé-Açu, state of Pará, in the Belém area of endemism; Peters, 1951). Plumage attributes Males similar to W. v. nigrigula overall, but without a black throat patch. Ventral region grey, with lighter throat. Females are also similar to those in W. v. nigrigula, but with the white interscapular spot absent or inconspicuous. Genetic differentiation Specimens with the plumage characteristics above belong to a genetic group with some geographic structuring recovered for the mitochondrial genes across the Tocantins River and which are referred herein as W. v. vidua A and W. v. vidua B. These groups are completely sorted for their mitochondrial DNA, but less so for the nuclear genes, occupying together the area comprised between the east bank of the Xingu eastward to Maranhão in easternmost Brazilian Amazonia (Fig. 1). Plumage variation We did not detect any conspicuous geographic variation in plumage that could be related to the comparatively shallow level of genetic structure recovered within this group.
