Engenho do Gama, Rio Guaporé, Mato Grosso, Brazil.
Usually considered conspecific with C. dissita (which see). Formerly considered conspecific with C. vulpecula, but the two are locally syntopic and widely sympatric, and field experiments suggest possible reproductive isolation created by song differences. Amazonian populations vary clinally in coloration of back and underparts; in N Brazil, proposed races alopecias (R Branco) and solimonensis (lower R Solimões) described on basis of less rufescent back and more ochraceous underparts, but not reliably distinguishable from nominate. Sight records from NC Bolivia (S Beni) presumed to be referable to race foxi. Four subspecies recognized.
